Hybrid pixel detectors represent the state-of-the-art technology for hard X-ray experiments at synchrotron light sources and free-electron lasers, owing to their high frame rates,…
Magnetic scattering experiments with an ultrashort pulsed soft X-ray source using iLGADs
L. Lunin, S. Li, A. Bergamaschi +38
Inverse Low Gain Avalanche Diode (iLGAD) sensors developed at the Paul Scherrer Institute (PSI) in collaboration with the Fondazione Bruno Kessler (FBK) have demonstrated an excell…
Enhanced micrometre spatial resolution and usable photon flux for hybrid pixel detectors via deep-learning-based X-ray localization
Xiangyu Xie, Anna Bergamaschi, Martin Brückner +30
Micrometre spatial resolution is achieved for X-rays with the MÖNCH detector, a charge-integrating hybrid pixel detector with a 25 μm pixel pitch, by exploiting charge sharing betw…
Non-destructive 3D doping imaging of silicon sensors
Xiangyu Xie, Anna Bergamaschi, Maria Carulla +9
Silicon sensors are the foundational detection medium for X-rays and charged particles. While their bulk dopant distribution determines device performance, it is conventionally ass…
