Neural network-based timewalk correction for the Timepix4 ASIC
David Bacher, Kazu Akiba, Martin van Beuzekom +7
Timewalk corrections of hybrid pixel detectors conventionally employ heuristic fits performed independently in bins of the relevant input variables. This requires both an explicit…
Leakage current evolution in LHCb VELO sensors during Run 1-2 LHC data taking period
M. Pycior, T. Szumlak, A. Oblakowska-Mucha +33
Silicon detectors operating in the harsh mixed-hadron radiation environment of modern high-energy physics experiments suffer progressive bulk damage, manifesting macroscopically as…
Testbeam characterization of a 3D silicon sensor read out by Timepix4
E. Chatzianagnostou, M. J. Madurai, K. Akiba +15
Testbeam results from a -thick 3D silicon sensor bump-bonded to a Timepix4 ASIC, are presented. The hit detection efficiency, spatial resolution, and timing perfo…
The Timepix4 Beam Telescope
Kazu Akiba, Jerome Alozy, David Bacher +40
The spatial and temporal performance of a telescope system comprising planar silicon sensors bump-bonded to Timepix4-v2 ASICs are assessed at the CERN SPS using a ~GeV/ mix…
