The Picosec detection concept consists in a two-stage Micromegas detector coupled to a Cerenkov radiator and equipped with a photocathode. A 1cm2 area prototype has already been built and characterized to prove this concept. A single-photoelectron response of 76 ps has been measured with a femtosecond UV laser at CEA/IRAMIS, while a time resolution of 24 ps with a mean yield of 10...

Diamond timing detectors were installed in CT-PPS Roman Pots in June
2016 and served for collecting 2.5 fb^-1 of data. During the LHC technical stop from Dec 2016 to Apr 2017 one plane of diamond detectors was removed from each detector package and replaced with Ultra-Fast Silicon Detectors (UFSD). This provided an opportunity to re-characterize the diamond detector performance after...

The expected increase of the particle flux at the high luminosity phase of the LHC (HL-LHC) with instantaneous luminosities up to L ≃ 7.5 × 1034 cm^{−2} s^{-1} will have a severe impact on the ATLAS detector performance. The pile-up is expected to increase on average to 200 interactions per bunch crossing. The reconstruction and trigger performance for electrons, photons as well as jets and...

Prototype beam monitoring devices are under development at the Torino section of INFN, with the goal of measuring the flux, the profile and the energy of charged particle beams, in particular for radiobiology and hadron-therapy applications. The devices will employ Ultra-Fast Silicon Detectors (UFSD), innovative silicon sensors optimized for timing measurements based on the Low-Gain Avalanche...

A Low Gain Avalanche Detector (LGAD) was used to characterize a linear accelerator (LINAC) used for radiotherapy at St. Luke Hospital in Dublin. The LINAC, manufactured by ELEKTA, can produce an electron beam with energies between 5 and 15 MeV in pulses of ~2 us with a substructure of 3 GHz. A tungsten target is used to produce up to 10^11 photons/s mm2 X-rays (bremsstrahlung) that are used...

The Scintillating Fibre (SciFi) Tracker is designed to replace the current downstream tracking detectors in the LHCb Upgrade during 2019-20 (CERN/LHCC 2014-001; LHCb TDR 15). Collecting data at the increased luminosity foreseen for the upgrade will only be possible with front-end electronics read out at 40MHz and a flexible software-based triggering system that will increase the data rate as...

With the enduring intensity increase of particle physics experiments at the precision frontier, high granularity timing detectors with excellent timing resolutions and very low additional material become crucial to control combinatorial backgrounds. Scintillating fibres combined to thin mats, read out with segmented silicon photomultipliers provide sub-nanosecond timing resolutions with...

Within the CALICE collaboration, several concepts for the hadronic calorimeter of a future linear collider detector are studied. After having demonstrated the capabilities of the measurement methods in "physics prototypes", the focus now lies on improving their implementation in "engineering prototypes", that are scalable to the full linear collider detector. The Analog Hadron Calorimeter...

The Large Hadron Collider (LHC) Phase II upgrade aims to increase the accelerator luminosity by a factor of 5-10. Due to the expected higher radiation levels and the aging of the current electronics, a new readout system of the ATLAS experiment hadronic calorimeter (TileCal) is needed. A prototype of the upgrade TileCal electronics has been tested using the beam from the Super Proton...

Particle detection is one of the pillars of the research in fundamental physics. Since several years, a new concept of detectors, called Micro Pattern Gas Detectors (MPGD), allows to overcome many of limits the preexistent detectors, like drift chambers and microstrip detectors, reducing the discharge rate and increasing the radiation tolerance.
Among these, one of the most commonly used...

Optically read out Gaseous Electron Multipliers (GEMs) are well suited for online monitoring of particle beams in high energy physics as well as medical fields. The high gain factors achievable by GEMs and the good spatial resolution enabled by state-of-the-art CCD or CMOS imaging sensors permit accurate beam profile and position monitoring over a wide range of beam energies, particle fluxes...

The NA64 experiment is a fixed target experiment at the SPS at CERN, searching for new physics using an active beam dump to detect missing-energy events. It employs a tracker based on multiplexed micromegas detectors, which presents a unique challenge with respect to reconstructing particle trajectories. In particular, the signature of dark photon (or alternatively $^8$Be anomaly X boson)...

For the high-luminosity upgrade of the CMS outer tracker, a new, MicroTCA-based read-out system is envisaged. In a recent beam test at DESY, the functionality of a prototype version of this system and its firmware was demonstrated. This contribution shows beam test results and comparisons to simulations.

For the HL- LHC the irradiation level that the detectors will have to withstand will be reaching a 1 MeV neutron equivalent fluence of 2×10^16neq/cm2 and a total ionizing dose of 10 MGy at the location where the sensors of the Inner Tracker will be installed.
The upgraded Phase-2 Inner Tracker is designed to maintain or improve the tracking and vertexing capabilities under these high pileup...

In phase II the LHC will be upgraded to the High Luminosity LHC. To fulfill the increased particle flux and higher instant luminosity, the ATLAS experiment will be equipped with a new Inner Tracker (ITk). Because of the close position to the beam line, the pixel modules of the ITk are exposed to high radiation.
Planar n-in-n silicon sensors with different pixel implantations have been...

The work is devoted to the study of the test beam performance of active and slim edge ATLAS planar pixel sensors (PPS) in various test conditions including irradiation fluences (1e15 and 2e15 neq/cm^2) and sensor inclination. CERN and DESY beam facilities have been used for the test beam performing.

3D silicon detectors, with cylindrical electrodes that penetrate the sensor bulk perpendicularly to the surface, present a radiation-hard sensor technology. Due to a reduced electrode distance, trapping at radiation-induced defects is less and the operational voltage and power dissipation after heavy irradiation are significantly lower than for planar devices. During the last years, the 3D...

A precise measurement of the arrival time distribution of ionisation charges in a reverse-biased single silicon pixel sensor layer can be used to determine the impact point, incident angle and direction of minimum ionising particles. This concept of a Silicon Time-Projection-Chamber could for example be used to reduce the number of sensor layers in large-area tracking detectors, or to improve...
