High-rate, high-resolution single photon X-ray imaging: Medipix4, a large 4-side buttable pixel readout chip with high granularity and spectroscopic capabilities
/ Sriskaran, Viros (CERN) ; Alozy, Jerome (CERN) ; Ballabriga, Rafael (CERN) ; Campbell, Michael (CERN) ; Christodoulou, Pinelopi (CERN ; CTU, Prague) ; Heijne, Erik (CTU, Prague) ; Koukab, Adil (Ecole Polytechnique, Lausanne) ; Kugathasan, Thanushan (CERN) ; Llopart, Xavier (CERN) ; Piller, Markus (CERN ; Graz, Tech. U.) et al.
The Medipix4 chip is the latest member in the Medipix/Timepix family of hybrid pixel detector chips aimed at high-rate spectroscopic X-ray imaging using high-Z materials. It can be tiled on all 4 sides making it ideal for constructing large-area detectors with minimal dead area. [...]

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. [...]

Determination of Luminosity With Thermal Neutron Counting Using TPX Detectors in the ATLAS Cavern in LHC Proton-Proton Collisions at 13 TeV
/ Sopczak, André (IEAP CTU, Prague) ; Ali, Babar (IEAP CTU, Prague) ; Begera, Jakub (IEAP CTU, Prague) ; Bergmann, Benedikt (IEAP CTU, Prague) ; Billoud, Thomas (Montreal U.) ; Biskup, Bartoloměj (IEAP CTU, Prague) ; Burian, Petr (IEAP CTU, Prague) ; Caforio, Davide (IEAP CTU, Prague) ; Heijne, Erik (IEAP CTU, Prague) ; Janeček, Josef (IEAP CTU, Prague) et al.
A network of Timepix (TPX) devices installed in the ATLAS cavern has the unique capability of measuring the luminosity with thermal neutron counting in Large Hadron Collider proton-proton collisions at 13 TeV. Compared with the hit-counting method, the method of thermal neutron counting has the advantage that it is not affected by induced radioactivity. [...]
