Detectors based on wide bandgap semiconductors and with high radiation hardness are very promising for many applications. The commercial availability of high-quality crystalline material is required for the preparation of high-grade radiation detectors. The 4H-SiC and diamonds are good candidates in term of harsh environment operation. Detectors based on SiC and diamond can operate at higher...

The European X-ray Free-Electron Laser (European XFEL) [1] is an international user research facility located in Schenefeld, in the Hamburg area. It currently features three undulators, providing spatially coherent X-rays for seven experimental stations in the energy range of 260 eV to 25 keV. Using superconducting cavities, the facility can provide up to 2700 pulses of up to...

The first electrons have circled the newly upgraded Swiss Light Source (SLS) 2.0, a fourth generation synchrotron. Photons with energies > 20 keV will be available at an increased flux compared to the third-generation synchrotron which has been replaced. Specifically, the brilliance will increase by two orders of magnitude. In these energy ranges, Silicon is no longer efficient as a detection...

Hybrid detectors are the state-of-the-art technology widely used in imaging experiments using hard X-rays. They are also highly attractive for soft X-ray experiments (200 eV – 2 keV) due to their high frame rate, large area coverage, and strong radiation tolerance. However, in the soft X-ray energy range, their performance is limited by the low quantum efficiency of silicon sensors, which are...

Low Gain Avalanche Detectors (LGADs) are silicon detectors produced in a specialized way, such that they possess an internal charge multiplication effect (gain) that amplifies the output signal and allows for a good signal-to-noise ratio. Their stable and controlled moderate gain of up to 50, along with exceptional timing resolution, justifies their role as a baseline for HEP experiments. This...

Although GaAs has been tested as a material for X-ray detectors for more than 50 years, practically significant results have only been achieved in the last decade, when semi-insulating, chromium-compensated single crystals have been employed [1]. This is particularly true for imaging sensors developed for Medipix/Timepix readout ASICs [1, 2].
We demonstrated imaging sensors fabricated by...

The MATRIX project explores advancements in proton therapy by developing durable detectors for improved real-time beam and dose monitoring. Proton irradiation enables precise tumor targeting while minimizing damage to healthy tissue. Current detection methods, including ionization chambers, scintillators, and silicon-based detectors, face limitations, particularly the degradation of silicon...

In recent years, the innovative concept of low internal gain avalanche detector (LGAD) coupled with the resistive read-out (RSD) has significantly changed the performance of silicon detectors. By increasing the ratio signal-to-noise by a factor of around 20, the LGAD mechanism led to unprecedented time resolution, on the order of 30 ps for a 50 um active sensor thickness. The resistive...
