Pixel detectors using single energetic quantum imaging: Past and future
/ Heijne, Erik H M (IEAP CTU, Prague ; CERN ; Nikhef, Amsterdam)
The early steps with 2-dimensional semiconductor detectors for particle physics experiments are briefly described. A comparison is made between monolithic devices, especially the CCD, and hybrid detectors, which combine a semiconductor sensor matrix with a separate ASIC in advanced CMOS technology. [...]

X-ray imaging is a widely used imaging modality in
the medical diagnostic field due to its availability, low cost, high
spatial resolution and fast image acquisition. X-ray photons in
standard X-ray sources are polychromatic [...]

Registration of the transition radiation with GaAs detector: Data/MC comparison
/ Alozy, J (CERN) ; Belyaev, N ; Bergmann, B L (IEAP CTU, Prague) ; Billoud, T R V (IEAP CTU, Prague) ; Broulim, P (Pilsen, Coll. Mech. Elect. Eng.) ; Burian, P (IEAP CTU, Prague ; Pilsen, Coll. Mech. Elect. Eng.) ; Campbell, M (CERN) ; Chelkov, G (Dubna, JINR) ; Cherry, M (Louisiana State U.) ; Dachs, F (CERN) et al.
New developments of pixel detectors based on GaAs sensors offer effective registration of the transition radiation (TR) X-rays and perform simultaneous measurements of their energies and emission angles. This unique feature opens new possibilities for particle identification on the basis of maximum available information about generated TR photons. [...]

Transition radiation measurements with a Si and a GaAs pixel sensor on a Timepix3 chip
/ Dachs, F (CERN ; TU Vienna) ; Alozy, J (CERN) ; Belyaev, N (Moscow Phys. Eng. Inst.) ; Bergmann, B L (CTU, Prague) ; van Beuzekom, M (Nikhef, Amsterdam) ; Billoud, T R V (Montreal U.) ; Burian, P (CTU, Prague ; Pilsen, Coll. Mech. Elect. Eng.) ; Broulim, P (Pilsen, Coll. Mech. Elect. Eng.) ; Campbell, M (CERN) ; Chelkov, G (Dubna, JINR) et al.
Growing energies of particles at modern or planned particle accelerator experiments as well as cosmic ray experiments require particle identification at gamma-factors ($\gamma$) of up to ∼ 10$^5$ . At present there are no detectors capable of identifying charged particles with reliable efficiency in this range of $\gamma$ . [...]
