7 Highlights of DTS: Lambda-SQUIDs SQUID-based superconducting microcalorimeters with in-situ tunable gain for high- resolution X-ray emission spectroscopy

Cryogenic microcalorimeters such as superconducting transition-edge sensors or magnetic microcalorimeters are outstanding devices for any application requiring an energy-dispersive photon detector with cutting-edge energy resolution and close to 100% detection efficiency. They are hence ideally suited for X-ray emission spectroscopy (XES) that relies on photon detection with utmost precision and highest efficiency. Nevertheless, cryogenic microcalorimeters can’t yet compete with state-of-the-art wavelength-dispersive grating or crystal spectrometers that often provide one or two orders of magnitude better energy resolution, at the cost of a significantly lower detection efficiency. However, as some applications such as XES of dilute or radiation sensitive samples requires both, utmost energy resolution and highest detection efficiency, at the same time, it is worth continuing to develop novel detector concepts that potentially bridge this gap. One such concept is the Lambda-SQUID that we have recently introduced and that is based on the strong temperature dependence of the magnetic penetration depth of a superconducting material that is operated below but close to its transition temperature. By embedding a coil made of this material directly into a dc-SQUID loop or into an intermediate flux transformer that is inductively coupled to a state-of-the-art dc-SQUID and using a special input circuit configuration, a temperature change of an X-ray absorber that is connected to the coil is transduced into a change of magnetic flux threading the SQUID loop. The resulting temperature-to-flux transfer coefficient can be tuned in-situ and allows suppressing SQUID noise well below the thermodynamic noise floor that is inherent to any cryogenic microcalorimeter. Moreover, the device promises to reach deep sub-eV energy resolution while maintaining a quantum efficiency close to 100%. In this contribution, we comprehensively discuss our novel detector concept and gauge its possible performance using device simulations and latest experimental data. Moreover, we discuss important design considerations such as the optimal choice of sensor and absorber heat capacity or the best device geometry. We finally summarize the latest stage of device development.

10 Soft and hard x-ray spectroscopy with a novel calorimetric superconducting quantum sensor

X-ray spectroscopy at synchrotron light sources has emerged as one of the most powerful tools available worldwide for the characterization of the chemical, atomic, and electronic properties of materials. While existing x-ray spectrometers provide either excellent energy resolution at low efficiency or moderate energy resolution at high efficiency, magnetic microcalorimeters (MMCs) might be a “gamechanger” as they promise outstanding energy resolution with a ΔE_FWHM of 1.25 eV at 5.9 keV [1], a large energy bandwidth, and extremely high detection efficiency. MMCs are ultra-sensitive cryogenic detectors which rely on converting the energy from incident photons into heat. Using an ultra-sensitive thermometer based on the temperature-dependent magnetization of a paramagnetic material in a weak magnetic field, the resulting change in magnetization is sensed with a superconducting quantum interference device (SQUID) [2].
The goal of our activities within the project “Quantum sensor platform for synchrotron x-ray spectroscopy (QUASY)”, is to demonstrate the feasibility of such a x-ray quantum sensor array at multiple synchrotron radiation beamlines (i.e., X-SPEC, CAT-ACT, INE, and SUL-X) at the KIT Light Source using a universal, compact, and modular platform. In this contribution, the current design concept of the platform, which contains x-ray optics and filter foils, will be discussed. We will show first experimental data on the thin filter foils that serve as candidates to block infrared radiation while transmitting x-rays in the soft, tender, and hard x-ray energy regions. If successful, the new instrumentation will not only greatly advance the available experimental techniques, but also allow for the study of samples containing radionuclide materials, with low concentrations, and/or in in situ and operando environments.

11 Assessment of the Intra-Beam Scattering and Touschek Lifetime in BESSY III

The 4th generation synchrotron light source, BESSY III, is expected to enable high-impact applications for users in life science, material science, solar cell technology, and more.
Currently in its Conceptual Design Report (CDR) phase, the feasibility of BESSY III's ambitious parameter range necessitates a thorough assessment of "collective effects". These effects are phenomena that can either compromise beam stability or degrade beam quality, potentially hindering the expected performance.
In this work, we present recent computations of the Intra Beam Scattering (IBS) and Touschek lifetime for the BESSY III lattice. The IBS leads to a significant increase of the final emittance of the light source, while the Touschek effect critically affects the beam lifetime. We discuss the computational methods employed, the strategies for mitigating these effects, the expected performance outcomes, and the specific challenges associated with ultralow emittance storage rings.

12 Automated optimization workflow to translate laser plasma acceleration experiments into PIC simulations

Modern laser-plasma accelerators require large-scale particle-in-cell (PIC) simulations to realistically model the three-dimensional relativistic laser-plasma interactions. The large number of possibly unknown laser and target parameters and their uncertainties in experimental setups prevent a simple translation of experimental setups into simulations and thus make meaningful statements about the prevailing dynamics difficult. In order to efficiently reproduce experiments PIC simulations were performed and their deviation from experimental results evaluated. To minimize this deviation, a feedback loop using Bayesian optimization was used to determine the next set of input parameters. We employed this method to self-truncated ionization injection experiments for electron acceleration at HZDR. It resulted in good agreement between simulation and experimental results after only a few simulations. Thus, saving computational resources compared to random parameter sampling. The simulations were performed using the open-source software PIConGPU, a multi-GPGPU PIC code that generates openPMD output at high throughput. It allows the simulation of dispersive lasers and their propagation over hundreds of thousands of time steps through complex targets. The iterative optimization scheme was implemented using Snakemake, a Python-based workflow engine that allows any number of computational jobs to be organized in a directed acyclic graph (DAG) and submitted to different compute clusters. The combination of PIConGPU and Snakemake allowed simulations to be compiled, run, and evaluated in an automated and parallel fashion, and the results used directly in the Bayesian optimization algorithm to obtain new input parameters. The developed workflow interface can be easily applied to any other multi-parameter PIConGPU simulation campaign and is now part of the publicly available PIConGPU codebase.

13 Sensor cracking studies with ATLAS ITk strips detector modules

During pre-production of the ITk strips tracking detector for the upcoming ATLAS upgrade a certain number of modules have been found to have sensor cracks after thermal cycling when being loaded on the final support structures.
A number of materials and different types of adhesive used in the complete assembly create localized stress points when cooled. This leads to cracks in the silicon at temperatures close to the final operating conditions.
Affected modules suffer from early sensors breakdown and broken strips.
In order to mitigate the potential loss of entire modules during detector operation, alternative methods of module assembly and loading onto the substructure have been investigated. Either a stiff Hysol adhesive bonding the silicon to the rigid support structure should reduce sensor flex. Alternatively, a thin capton layer between the sensor and the attached circuit boards should absorb some of the stress and form so-called interposer modules.
This poster presents the studies that have been carried out on pre-production petals to investigate the conditions under which cracks occur and their failure modes. In particular, a comparison is made between the proposed solutions.

14 HZB Cyclotron beyond therapy: expanding into radiation hardness and radiobiology

The HZB cyclotron continues to provide protons for eye tumor treatment in collaboration with the Charité – Universitätsmedizin Berlin after 26 years and more than 4600 patients so far. Apart from the therapy, the provided beam is in great demand by various applications that range from radiation hardness tests to biological research. For this reason, the facility is currently extended to include two additional target stations: (i) one that will enable in-operando characterization of radioresistant perovskite-based solar cells and detectors under proton irradiation and (ii) one for in-vitro and in-vivo experiments with proton mini-beams, a novel irradiation approach in radiotherapy that promises to reduce side effects. An overview of the current plans and progress of the facility upgrade is presented here.

15 Fourier propagators as synthetic diagnostics in PIConGPU

We present a synthetic Shadowgraphy Plugin for the particle-in-cell code PIConGPU. By time-integrating electric and magnetic fields and propagating them onto a screen in the far field with Fourier methods, shadowgram images equivalent to experimental measurements can be produced.

Our in-situ plugin now enables recording few-cycle probe pulses after they traverse plasma structures of e.g. laser-plasma accelerators with the PIC algorithm. The so generated images contain the full laser-plasma interactions in contrast to traditional post-processing approaches. By analyzing these shadowgrams alongside the 3D, time-resolved density distribution from the simulation, one can trace the origin of specific features.

We also show validation tests, that confirm the conservation of physical quantities and the plugin performing as expected. This allows to quantitatively predict and analyze shadowgrams.

16 Wakefield-based bunch duration diagnostics with dielectric capillaries at ARES for the TWAC project

The EIC-Pathfinder project TWAC (Terahertz Wave Accelerating Cavity) aims to build a prototype accelerator demonstrating the feasibility of a compact machine based on THz-driven accelerating structures for the purpose of research, medical and industrial applications. The prototype should deliver low-energy, ultrashort and high peak current electron bunches (~10 MeV, femtosecond scale and ~1 kA) on a small footprint. Within the framework of the TWAC project, DESY is in charge of developing and experimentally testing compact advanced bunch duration diagnostics for the prototype. The retained option is a diagnostics based on streaking of the bunch by the self-induced transverse wakefields when passing through a dielectric-loaded cylindrical waveguide (the so-called passive streaking). To study the performance of this diagnostic, a proof-of-principle experiment has been carried out on the ARES linear electron accelerator at DESY, whose versatility allowed setting up several working points to approach iteratively the beam parameters expected in TWAC, which are far from the current range of applicability of passive streaking. In addition, ARES offers a benchmark possibility through a comparison with an X-band transverse deflecting structure (PolariX-TDS). In this contribution, we present the experimental setup installed at ARES, the development of a current profile reconstruction algorithm from the experimental data as well as the first passive streaking results at ARES and their comparison with PolariX-TDS measurements.

17 POEMMA Balloon with Radio and Electromagnetic Interference measurements

The POEMMA Balloon with Radio is a balloon experiment built on the designs tested in the previous EUSO missions. It is set to comprise an optical telescope with a fluorescence camera, a Cherenkov camera and radio instruments. These detectors are expected to measure UHECRs, high altitude horizontal air showers and any possible neutrino events. Measurements of potential Radio Frequency Interference (RFI) from the Fluorescence Camera (FC) is an essential step into conducting radio measurements of cosmic rays and neutrinos. This work discusses the Electromagnetic Interference measurements of the Photo Detection Modules that make up the FC that were conducted in a semi-anechoic chamber for this purpose.

18 Performance scaling with multicore fiber based laser systems

Fiber laser systems are reputed for being able to provide emission at high average powers while keeping nearly diffraction-limited beam quality. However, achieving pulsed operation with high peak-powers has traditionally been a challenge due to the small confinement of the light in the fiber causing the onset of nonlinear effects. A successful strategy to overcome these limitations is the parallelization using coherent combination of pulses emitted by multiple amplifier. This technique has been developed in the last decade and it has resulted in the achievement of record performance values of over 10kW average power and 32mJ pulse energies. However, both the complexity and footprint of these systems grow linearly with the channel count and, therefore, new architectures are required for further power scaling opportunities. One of such alternative architecture is the multicore fiber, which has the potential to allow for laser systems with a massive number of amplification channels while maintaining a compact footprint and manageable component count. In this contribution, we will present experimental results based on multicore fibers with up to 49 cores. Based on the coherent combination concept, femtosecond pulses with high beam quality could be realized with kW-level average powers. Using incoherent beam combination, nanosecond pulses with over 100mJ energy could be demonstrated. Additionally, we will provide an outlook towards multicore fibers capable of multi-kW average power with > 1J pulse energy.

19 BEETLE – High average power laser-plasma accelerator using a 1 kW Yb-based laser with nonlinear compression

Laser-plasma acceleration (LPA) is a promising technology for a future compact accelerator. However, current Ti:Sapphire laser technology typically supports few-hertz repetition rates, with scaling to higher rates being challenging. High energy, kHz-level Yb-based laser systems have longer, sub-picosecond pulses. After nonlinear spectral broadening in a multipass cell, these pulses can be compressed to tens of fs duration, becoming a promising LPA driver alternative.
In this poster, we introduce the BEETLE project, recently initiated at DESY, that aims to demonstrate high-energy, high repetition rate electron acceleration. The driver laser pulses, provided by a 5 kHz Yb-based laser system (Trumpf Scientific Lasers), have an energy of 200 mJ and are compressible to ~30 fs via spectral broadening. We present an overview, goals and the current status of the project.

37 Novel strategies for high-granularity and radiation hardness LGAD sensors

Low-gain avalanche diodes (LGADs) are being considered as a viable solution for 4D-tracking due to their excellent time resolution and good resistance to high radiation fluence. However, conventional LGAD sensors have a limited pixel dimension of 0.5-1 mm due to the presence of a non-sensitive region between pixels. This region, typically 60-70 μm wide, is the main factor restricting the decrease in pixel size for LGADs. As part of the RD50 collaboration, Trench-Isolated LGAD (TI-LGAD) sensors have been developed and fully characterized at KIT. These sensors have small pixels as small as 50 μm and a 100% fill factor.
This contribution will discuss the layout design rules, parameters, and their impact on the performance of spatial, time, gain, and noise. In addition, based on the accumulated results and experiences, an engineering run design has been developed at KIT and is currently undergoing production. The design contains pixelated and microstrip sensors, with a channel pitch as small as 25 µm, and is expected to achieve a time resolution below 20 ps. The production batch is split into several processes to ensure the production of devices suitable for particle physics, modern photon sciences, and space applications. At present, FBK is in the process of manufacturing these sensors, and the delivery is scheduled to be in November 2024.
Moreover, KIT is collaborating with the Santa Cruz Institute for Particle Physics to design a novel structure based on segmented thin LGADs known as Deep-Junction LGADs, which ensure very high gain uniformity combined with the excellent time and spatial performance. By adjusting the design and controlling the p/n degradation caused by radiation damage, this type of LGAD has the potential to significantly increase the radiation-hardness of LGADs.

The primary goal of this development and its subsequent production is to enhance silicon sensors, resulting in improved time, energy, and position resolution within the Helmholtz system. The successful implementation aims to establish the availability of sensors with high spatial (20 µm) and time resolution (20 ps) for charged particles, therefore contributing to milestone MT DTS-2.

38 Results from commissioning the Serenity-S1, a production optimised CMS Phase-2 back-end ATCA blade

The Serenity-S1 is a Xilinx VU13P-based Advanced Telecommunications Computing Architecture (ATCA) processing blade that was developed to be used for the Phase-2 upgrade of the CMS experiment. So far, given its general purpose, the blade is planned to be used in multiple CMS subdetector systems; KIT is involved in the Tracker and HGCal. Furthermore, the board is also planned for the Tristan detector at KATRIN.
We provide results on the serial link performance of the Serenity-S1 and on the board's power supplies under very high loads to test the board's reliability against large transients. Furthermore, we will present the current status of hardware and software development. Finally, preparations for the mass production of more than 700 Serenity-S1 boards starting in 2025 will be presented.

39 MKID Readout Electronics for the BULLKID-DM Experiment

The BULLKID-DM experiment aims to detect WIMP-like particles with masses below 1 GeV/c2, which are potential candidates for Dark Matter. Sensing these particles is difficult, as it requires nuclear recoil detectors with energy thresholds with hundreds or tens of eV, thus exceeding the capabilities of conventional semiconductor detectors. BULLKID-DM intends to tackle this challenge by using cryogenic microwave kinetic inductance detectors (MKIDs) with exceptional energy resolution to sense a target with a total mass of around 800g, divided into over 2000 silicon dice.
KIT joined the BULLKID collaboration and currently develops the room-temperature readout electronics needed to interface the frequency-multiplexed MKIDs. Since the readout requirements are similar to microwave-SQUID- multiplexed magnetic microcalorimeters (MMCs), the readout concept we originally proposed for the ECHo experiment has partially been reused. We ported the system to the ZCU216, a commercial evaluation card built around a Radio-Frequency System-on-Chip (RFSoC) with integrated high-speed data converters, and attached a custom analog front-end for signal conditioning. Recent efforts were aimed at generalizing our existing firmware modules to enable convenient adaptation to specific requirements of current and future experiments. In this contribution we will outline and evaluate the BULLKID-DM readout system design including the selected hardware components and the FPGA-firmware containing the real-time signal processing stages for tone generation, frequency demultiplexing and event triggering.

40 Transition Edge Sensors for Fundamental Physics

Cryogenic detectors have become a great asset to fundamental science including astrophysics, particle physics, and materials science: These detectors promise extremely low noise as well as high efficiency and an unprecedented energy resolution compared to conventional semiconductor sensors. They are well suited for the detection of very low energy particles and are ideal sensors for searching for extremely rare events, such as those caused by the interaction of hypothetical axions or by a direct interaction with dark matter particles. We have been developing a program to characterize superconducting transition edge sensors (TES) and setting up TES systems optimized for rare event searches. This includes simulations to better understand the TES behavior and reduce background, as well as optimizing the analysis to increase the sensitivity for such searches. In the presentation, we will summarize the current status of the work, as well as available infrastructure, applications and plans. These include direct dark matter searches with our TES systems, a measurement of the even number photon distribution of a quantum-squeezed light source and an independent detection system to search for an axion signal at the ALPS II experiment.

LHCb experiment plays an important role in the study of rare decays of hadrons with heavy quarks, and in the search for interactions and particles beyond the Standard Model.
Upgrade II of the experiment would enable data taking during the high luminosity phase. A hybrid tracking detector, consisting of scintillating fibers in the outer region and HV-CMOS pixel sensors in the inner region is considered to be the most promising concept for the tracking system of the Upgrade II. The focus of our group at KIT (ADL) would be the development of the HV-CMOS sensor chip for this detector. The installation of the detector is foreseen for the Long Shutdown 4 (2033-35).

52 Development of CoRDIA: An Imaging Detector for Next-Generation Synchrotron Rings and Free Electron Lasers

The current or planned upgrades of most radiation sources – for Free Electron Lasers towards faster continuous operation at a few 100kHz, and for synchrotron rings towards the diffraction limit, require a new generation of detectors to profit from this step. For diffraction limited sources like Petra IV an increase in brightness by two orders of magnitude is expected compared to Petra III. To cope with this increase, an extension of the dynamic range by the same factor or a frame rate about 100 times higher than current systems can be derived as specification.
The acronym CoRDIA stands for Continuous Readout Digitising Imager Array, and is a hybrid pixel detector development targeted on these next-generation synchrotron sources and Free Electron Lasers. Serving the latter it builds upon the concept of the AGIPD detector, employing a charge sensitive preamplifier with adaptive gain switching. The further signal path comprises of a Correlated Double Sampling stage and an 11bit Analogue to Digital Converter (ADC), serving a sub array of 16 pixels. 128 ADCs connect to a multi-gigabit serial link to drive the images off chip. For this part CoRDIA adopts the implementation on the Timepix4 chip by Nikhef. An Application Specific Integrated Circuit with 256 × 192...224 pixels will implement 24...28 of the previously described blocks. Since the links conform to industry standards (IEEE 802.3ae), the subsequent data acquisition can be based on commercial components (e.g. Field Programmable Gate Array cards connected via multi-fibre optical links). Performance targets are a continuous frame rate of ≈150kHz, and singe-photon sensitivity at ≪12keV, and a dynamic range of a few thousand photons (@ 12keV) with a silicon sensor. The energy range could be extended using active sensors or sensors from ”high-Z” materials towards lower and higher photon energies.

53 Milestones of the ALICE ITS3 vertex detector development: Advances in MAPS technology and detector performance

Using the example of the future ALICE vertex detector (ITS3),
this talk aims at providing an overview on cutting-edge developments at
the front of Monolithic Active Pixel Sensors (MAPS). These CMOS pixel
sensors offer mechanical flexibility and a low power consumption, while
maintaining excellent hit detection efficiency and spatial resolution.
Featuring wafer-scale, stitched sensors, which are bent to form a truly
cylindrical detection layers, the ITS3 concept pushes the limits in terms
of detection performance, while dramatically reducing the material budget.

Introducing the novel detector concept, via the characterisation of small-scale
pixel sensor prototypes produced in the 65 nm CMOS technology node, to first
results of large-area, stitched sensors, milestones of the ITS3 development are presented.
Here, the focus will be on the detection performance and power consumption
of the prototypes as well as in-beam characterisation of large-scale sensors.
Furthermore, the technique of material budget imaging is used to investigate
the scattering properties of a light-weight tracking detector mock-up.

54 Detection Challenges in the LUXE Strong-Field QED Experiment

LUXE (Laser Und XFEL Experiment) is a new experiment that is part of the DESY high-energy physics on-site program. It aims to combine a high-intensity optical laser with the 16.5 GeV electron beam of the European XFEL to explore the uncharted terrain of Quantum Electrodynamics (QED) at the strong-field frontier.

The experiment will measure the spectra of electrons, positrons, and photons resulting from the interaction of the two beams. The expected ranges of these measurements will depend on the laser power and focus, with a frequency of 1 Hz bunch crossing. These measurements must be performed in the presence of a low-energy, high radiation background. To meet these challenges, the experiment will use Cherenkov radiation detectors, scintillator screens, sapphire sensors, and lead-glass monitors for backscattering off the beam dump to handle high-rate electron and photon fluxes. A four-layer silicon-pixel tracker and a compact electromagnetic tungsten calorimeter will be used to measure the positron spectra. The layout of the experiment and the expected performance of each detector system under the harsh radiation conditions will be presented.

The experiment could be constructed to start operating by 2030 in Hamburg, using an existing 40 TW laser system to collect and analyze the first scientific data. It will then be upgraded to a 350 TW system to study the non-perturbative regime in detail.

55 Detectors for ultra-fast radiation therapy

FLASH radiation therapy is a new cancer treatment technique. It provides the same tumour control as conventional radiation therapy but shows increased tissue sparing. Tumours are irradiated with the same dose but with increased dose rate (>> 40 Gy/s) compared to conventional dose rate (0.05 Gy/s).
A new R&D facility for radiation therapy studies, called FLASHlab@PITZ, is being setup at the Photo Injector Test facility at DESY in Zeuthen (PITZ). It can provide worldwide unique beam parameters regarding delivered dose and dose rate. With an average dose rate within one RF pulse of up to 10^9 Gy/s and peak dose rates up to 4x10^13 Gy/s, PITZ is fully capable of ultra-high dose rate experiments.
Nevertheless, dosimetry is a major challenge. Traditional detectors suffer from saturation and cannot provide reliable measurements up to such high dose rates. The goal is to test and benchmark detectors that cover the whole range of dose rates available at PITZ.

61 From Python Tools to Middle Layer

Systems with many different components and different users require abstractions to make them accessible. For the currently most popular language in the science and data science community, Python, we created our own abstractions. So did others and a harmonization makes sense. This talk will cover the needs, our existing solution and give an outlook to the community wide emerging approaches to this topic.

68 TEMPUS, a Timepix4-based detector for Photon Science

A new readout chip has been recently produced by the Medipix4 collaboration: Timepix4, which combines photon-counting full-frame readout mode and event-driven time-stamping mode, with greatly enhanced performance over both Medipix3 and Timepix3. The single chip TEMPUS (Timepix4-based Edgeless Multi-Purpose Sensor) detector is being developed as a replacement to LAMBDA. With 512 x 448 pixels, 55 um pixel size, the chip offers a larger pixel area than its predecessors: 10 times higher count rate in the the photon-counting mode, and run up to 40 kHz frame rate. The tests we are reporting here however were done using the event-driven mode. In this mode, a relatively high time resolution can be achieved. Several experiments have already taken place at PETRA III, ESRF and Eu.XFEL. We were able to capture the electron bunch structure at these facilities. Also, when using a 300 um p-on-n sensor fully biased, time resolutions as low as few ns were achieved. When running at full speed, the 16 gigabit wireline transmitter (GWT) responsible for sending the data out of the chip, will reach a total bandwidth of over 80 Gbps. Dealing with this large amount of data is one of the main challenges ahead. The chip was also designed to take full advantage of the through silicion vias (TSV) technology and therefore we will be able to fully remove the wirebond connections on the sides, decreasing the dead areas when placing several chips together, which is also planned for future iterations of the prototype.

69 Cross-Chip Partial Reconfiguration for the Initialisation of Modular and Scalable Heterogeneous Systems

The almost unlimited possibilities to customize the logic in an FPGA are one of the main reasons for the versatility of these devices. Partial reconfiguration exploits this capability even further by allowing to replace logic in predefined FPGA regions at runtime. This is especially relevant in heterogeneous SoCs, combining FPGA fabric with conventional processors on a single die. Tight integration and supporting frameworks like the FPGA subsystem in Linux facilitate use, for example, to dynamically load custom hardware accelerators. Although this example is one of the most common use cases for partial reconfiguration, the possible applications go far beyond. We propose to use partial reconfiguration in combination with the AXI C2C cross-chip bus to extend the resources of heterogeneous MPSoC and RFSoC devices by connecting peripheral FPGAs. With AXI C2C it is easily possible to link the programmable logic of the individual devices, but partial reconfiguration on peripheral FPGAs utilising the same channel is not officially supported. By using an AXI ICAP controller in combination with custom Linux drivers, we
show that it is possible to enable the PS of the heterogeneous SoC to perform partial reconfiguration on peripheral FPGAs, and thus to seamlessly access and manage the entire multi-device system. As a result, software and FPGA firmware updates can be
applied to the entire system at runtime, and peripheral FPGAs can be added and removed during operation.

71 Tangerine

The TANGERINE project investigates a novel 65nm CMOS imaging technology for the next generation of lepton collider vertex/tracking detectors since monolithic active pixel sensors are a promising candidate to fulfil the stringent requirements set by next-generation experiments. The project aims for a spatial resolution of 3um with a temporal resolution below 10 ns while limiting the material budget to 50um silicon. These specifications make a larger-scale prototype an optimal candidate for a beam telescope as an intermediate step.

The investigation of a new process requires detailed studies of basic charge collection properties. A generic workflow for sensor simulations has been set up, built around detailed device simulations based on generic doping profiles combined with Monte Carlo simulations of charge deposition and collection to predict charge collection properties of different sensor geometries and designs. In parallel, three prototypes (MLR1, APTS and DESY ER1) have been designed and tested in laboratory and test beam campaigns. This contribution is going to summarise the simulation and testing efforts with a focus on the most recent studies.
