The Muon Drift Tube (MDT) chambers provide very precise and reliable muon tracking and momentum measurement in the ATLAS muon spectrometer. Already in Run 2 of the LHC they have to cope with very high background counting rates up to $500 Hz/cm^2$ in the inner endcap layers. At High-Luminosity LHC (HL-LHC), the background rates are expected to increase by almost a factor of 10. New small (15...

Dual-energy (DE) chest x-rays (CXRs) provide the ability to selectively imaging two relevant materials, soft tissue and bone structures, to better characterize various chest pathologies and potentially improve diagnosis of CXRs. Recently deep-learning-based image synthesis techniques have attracted much attention as another approach to replace exist DE methods (i.e., dual-exposure based,...

The presentation will describe the performances of planar hydrogenated amorphous silicon (a-Si:H) sensors with charge selective contacts developed in the framework of the fabrication of a 3D a-Si:H sensor. These devices were developped as an intermediate technological step towards the final detector but they have interseting flux/dose measuring capabilities by themselves.

Gas Proportional Scintillation Counters (GPSC) exploit the photon emission from the de-excitation of noble gas atoms as a detection mechanism. The size of the detector radiation window relative to the photosensor active area has always been a limitation in this type of detectors, since the amount of light collected by the photosensor may vary according to the axial distance of the incident...

The Cooling Storage Ring of the Heavy Ion Research Facility in Lanzhou (HIRFL-CSR) is constructed to study nuclear physics, atomic physics, interdisciplinary science, and relative applications. There are many different kinds of detectors for radiation imaging in the experiments at HIRFL-CSR. To reduce the development time, production cost, and maintenance difficulties of the readout...

To adopt monolithic active pixel sensors for space-based applications requires to lower their power consumption and to optimize the heat dissipation, to fulfill the constraints imposed by satellite power and cooling capacity. MAPS will be used for the first time in space within the High Energy Particle Detector, onboard the CSES-02 satellite. Space-register requirements are met with a parallel...

The CMS experiment will exploit the Gas Electron Multiplier (GEM) technology for the first time during the next LHC run. These detectors will work with Ar/CO2 (70/30) gas mixture at an effective gas gain of around 2×104. Maintain the gas mixture quality and concentration is fundamental for the safe and correct operation of such gaseous detectors. An Ar concentration 1% higher or lower will...

The High Luminosity phase of the Large Hadron Collider (HL-LHC) that will follow the 3rd Long Shutdown of the accelerator opens the window to a very rich and ambitious physics program, exploiting an integrated luminosity of 3000 fb$^{-1}$. During the HL-LHC operation, the instantaneous luminosity will be increased to 5$\times$10$^{34}$cm$^{-2}$s$^{-1}$, i.e. five times the machine’s original...

The Wuwei radiotherapy centre is the first carbon ion therapy facility in China .It can deliver 12C6+ beam with the energy up to ~410 MeV/A. The beam delivery system in the therapy facility ensures the beam energy deposition can cover the dedicated region in the body. It has been shown that Monolithic Active Pixel Sensors (MAPS) are very promising tools for direct online beam monitoring. Thus,...

The Ce3+ activated Y3Al5O12 (YAG:Ce) is a fast and efficient inorganic scintillator widely used in electron and X-ray detection systems. The single crystals of YAG:Ce achieve 90-120 ns decay constant of the scintillation pulse and light yield up to 30 000 photons/MeV. In previous studies, we have shown that RE3+ codoping of YAG:Ce and the...

This contribution presents an update on the Analytical Method (AM) algorithm for trigger primitive (TP) generation in the CMS Drift Tube (DT) chambers during the High Luminosity LHC operation (HL-LHC or LHC Phase 2). The algorithm has been developed and validated both in software with an emulation approach, and through hardware implementation tests. The algorithm is mainly divided in the...

Hybrid pixel detectors for radiation imaging suitable for 3-D particle tracking and reconstruction offer the capability of high-resolution measurement of Time-of-Arrival (ToA) parameter. ToA is the amount of time between the discriminator first edge and the moment when the shutter closes. Possible applications include electron microscopy and antimatter research [1]. For example, 1.58 ns ToA...

In a multi-channel radiation detector readout system, waveform sampling, digitization and transmitting bits to the data acquisition system constitutes a conventional processing chain. The quantities, such as time-of-arrival and signal magnitude, i.e. deposited energy is estimated by fitting analytical models over the acquired digital data extracting starting times of signals, peak amplitudes,...
