Timing resolution performance of Timepix4 bump-bonded assemblies
/ Bolzonella, R. (INFN, Ferrara) ; Alozy, J. (CERN) ; Ballabriga, R. (CERN) ; van Beuzekom, M. (NIKHEF, Amsterdam) ; Biesuz, N.V. (INFN, Ferrara) ; Campbell, M. (CERN) ; Cardarelli, P. (INFN, Ferrara) ; Cavallini, V. (INFN, Ferrara) ; Coco, V. (CERN) ; Cotta Ramusino, A. (INFN, Ferrara) et al.
The timing performance of the Timepix4 application-specific integrated circuit (ASIC) bump-bonded to a $100\;\mu\textrm{m}$ thick n-on-p silicon sensor is presented. A picosecond pulsed infrared laser was used to generate electron-hole pairs in the silicon bulk in a repeatable fashion, controlling the amount, position and time of the stimulated charge signal.
