Development of superconducting undulatorsSince several years, KIT IBPT and the industrial partner Babcock Noell GmbH (BNG) are collaborating to develop superconducting undulators for ANKA and low emittance light sources. The first full length device with 15 mm period length has been successfully tested in the ANKA storage ring for one year. The next superconducting undulator has a period length of 20 mm(SCU20) and is planned to be the source of the NANO beamline at ANKA. The cryostat has been manufactured, the beam vacuum chamber and the superconducting coils have been successfully tested.Speaker: Dr Sara Casalbuoni (IBPT-KIT)

DAQ Test System for CMS Tracker Upgrade Phase 2The upcoming high-luminosity phase of the LHC requires an upgrade of the tracking detector of the CMS experiment. Two types of detector modules are foreseen to be used for the outer tracker regions: so called 2S and PS modules. The current design of the modules implies the presence of two semiconductor sensors with corresponding front-end electronics for the readout. For the future module production at DESY, testing infrastructure is being developed, based on the FC7 test board. The FC7 is a 𝜇TCAcompatible Advanced Mezzanine Card for generic data acquisition and control applications. Developed by Imperial College London and built around the Xilinx Kintex 7 FPGA, the FC7 provides a large array of configurable I/O ports, primarily delivered by on-board FPGA Mezzanine Card (FMC) headers, which give the opportunity to establish an optical or electrical interface between the FC7 and the front-end electronics of the CMS tracker’s modules. The poster will present the concept of the test bench and the development status of the FC7 firmware.Speaker: Mr Mykyta Haranko (DESY, CMS Group)

Femtosecond Level Laser Synchronization at REGAERelativistic Electron Gun for Atomic Exploration (REGAE) is a unique accelerator, capable of producing ~ 10 fs long electron bunches. These bunches are used for Ultrafast Electron Difraction (UED) experiments in a pump-probe configuration. In order to conduct precise pump-probe experiments one has to ensure femtosecond level laser synchronization. This poster presents advanced Mach-Zehnder Modulator based laser-to-RF synchronization setup realized for Titanium Sapphire laser system and corresponding measurement results.Speaker: Mr Mikheil Titberidze (DESY)

ChimeraTK: A tool kit for modular control applicationsChimeraTK (formerly called MTCA4U) is a collection of C++ libraries which facilitate the development of control applications. Special importance has been placed on abstraction from communication layers to simplify writing applications in heterogeneous environments or reusing applications in different facilities. In close collaboration between DESY, HZDR, TU Dresden and Aquenos GmbH a control system adapter has been developed. It allows to operate the same application with different SCADA systems and in different control system environments, without changing a single line of code in the application proper. As a first project a Low Level RF controller server has been ported to the adapter. SCADA plugins for DOOCS, OPC-UA and EPICS 3 have been implemented, which will be used for FLASH and the European XFEL at DESY, ELBE at HZDR, and FLUTE at KIT, respectively. In addition to the control system adapter, ChimeraTK features the DeviceAccess library with an extensible register-based interface and the VirtualLab library for code testing and simulation. Written in modern C++ and published under the open GPL and LGPL licenses, ChimeraTK is designed to foster the collaboration between different facilities, especially in the accelerator and research community.Speaker: Martin Killenberg (DESY)

Design of a longitudinal electron diagnostics using THz fields excited in split ring resonator at FLUTELongitudinal electron diagnostics with high temporal resolution is increasingly demanded, especially for free-electron lasers. Strong THz fields, excited in a split ring resonator (SRR), have been recently proposed to streak electron bunches for their temporal characterisation. Thanks to the high amplitude and frequency of the THz field, longitudinal resolution down to the sub-femtosecond range can be expected. A proof-of-principle experiment of the SRR longitudinal diagnostics is planned at the accelerator test facility FLUTE (Ferninfrarot Linac und Test Experiment) at the Karlsruhe Institute of Technology. The design of the experimental chamber has been finished and integrated into the FLUTE accelerator beam line. Beam dynamics simulations have been conducted to investigate and optimise the performance of the SRR diagnostics. In this contribution, we present the design layout of the experimental setup and discuss the simulation results for different parameters of the accelerator and the SRR structure.Speaker: Dr Minjie Yan (KIT)

Simulating laser wakefield acceleration with PIConGPU - from modeling the laser plasma dynamic to in-situ radiation calculationWe recent simulations of laser wakefield acceleration on recent experiments performed at HZDR. We focus on how to best approximate the experimental setup using newly developed laser-models, as well as particle creation- and ionization-methods. Furthermore, we elaborate on predicting experimentally observable radiation signatures from the simulation. We discuss in detail the influence of various ionization mechanisms, including BSI, ADK and Keldysh, and how to model the initial gas or plasma distribution. Furthermore, we present recent improvements in the laser implementation, that added Laguerre-Gauss modes, which drastically reduces discrepancies between previous simulations and experiments. On top of simulating plasma dynamics, we present how to predict experimental observables using PIConGPU’s in-situ synthetic diagnostics, especially the classical Liénard-Wiechert potential- and QED-based radiation. It allows predicting both coherent and incoherent radiation spectrally from infrared to x-rays and provides the capability to resolve the radiation polarization as well as determine its temporal and spatial origin. On the examples of a large-scale LWFA simulation, we illustrate how we reduce the gap between simulated plasma dynamics and radiation observed in experiments and discuss valuable spectral signatures which allow conclusions on the micrometer femtosecond electron dynamics during acceleration.Speaker: Mr Richard Pausch (HZDR)

Computing strategy to cope with the upcoming massive HEP and HI data collectionThe LHC scientific program has led to numerous important physics results. This would not have been possible without an efficient processing of PetaBytes of data using the Worldwide LHC Computing Grid (WLCG). In the periods following the accelerator and detector upgrades, a huge increase in the data rate is expected. In addition, other big experiments like BELLE-2 and the FAIR collaborations will also take large amounts of data during the next years. So far the LHC computing strategy, based on Grid computing as a distribution of data and CPUs over a few hundred of dedicated sites, has met the challenges. However, to cope with substantially increased data volumes and correspondingly higher CPU requirements, new techniques like cloud computing and the usage of opportunistic resources are necessary. In parallel a reorganisation of the interplay of the computing sites is presently addressed by the evolving computing models of the affected experiments. Recently the Technical Advisory Board of the WLCG German Tier-1 site GridKa in Karlsruhe organised a meeting aimed to identify the guidelines for keeping German HEP and Heavy Ion computing excellent for future requirements. In a follow-up meeting working groups were launched in order to effectively organise the work on the above topics. The presentation will address the challenges, the German strategy, and the current status of the work packages.Speaker: Dr Kilian Schwarz (GSI)

Ultimate Heavy Ion IntensitiesTo generate ultimate heavy ion beam intensities in synchrotrons, low charge states have to be used. This avoids stripping losses and the space charge limit is shifted to higher number of particles. But at the same time, the probability for charge exchange in collision with residual gas molecules of such ions is much higher, than for highly charged heavy ions. Ionized ions are deflected different, than the reference ion and will get lost. At the position of impact on the beam pipe vacuum chamber, they induce a desorption process, which significantly increases the residual gas density in this area. This in turn increases the probability for further charge exchange processes, whereby a self-amplification up to complete beam loss can evolve. This mechanism limits the maximum possible heavy ion intensity. To shift this limit to higher number of particles, several measures are possible. One is, to reduce the residual gas pressure, another is to reduce the number of desorbed gas particles by heavy ion impact. Both measures are subject of accelerator research within ST2. A cryogenic environemt provides high pumping speed for all heavy residual gas particles. According to the vapour pressure courves, their partial pressure is reduced to ultimate low pressures. At 5K-15K, the typical operation temperature of cryogenic vacuum chambers cooled by liquid helium, hydrogen does not get condensated to acceptable low pressures. Hydrogen only gets adsorbed by the cold walls. This adsorption process also leads to sufficiently low pressures, although the capacity is limited. The investigation of capacity and pumping speed as a function of the temperature has been investigated. The understanding of the desorption process on cryogenic and room temperature surfaces is the other subject of investigations. The temperature and energy dependence of the desorption yield by heavy ion bombardement has been investigated for different materials, as well as the energy dependence of several room temperature materials. The result of all research subjects is condensed into the StrahlSim simulation code, which simulates the interaction bebween residual gas and heavy ion beam. The time dependent temperature change of cryogenic magnet chamber walls has newly been implemented. First results of dynamic vacuum simulations using dynamic chamber temperatures will be shown.Speaker: Dr Lars Bozyk (GSI)
