002900400 520__ $$9IOP$$aThe timing performance of the Timepix4 application-specificintegrated circuit (ASIC) bump-bonded to a100 μm thick n-on-psilicon sensor is presented. A picosecond pulsed infrared laser wasused to generate electron-hole pairs in the silicon bulk in arepeatable fashion, controlling the amount, position and time of thestimulated charge signal. The timing resolution for a single pixelhas been measured to 107 psr.m.s. for laser-stimulated signals in the silicon sensorbulk. Considering multi-pixel clusters, the measured timingresolution reached 33 psr.m.s. exploiting oversampling of the timing information overseveral pixels.

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. The timing resolution for a single pixel has been measured to $107\;\textrm{ps}$ r.m.s. for laser-stimulated signals in the silicon sensor bulk. Considering multi-pixel clusters, the measured timing resolution reached $33\;\textrm{ps}$ r.m.s. exploiting oversampling of the timing information over several pixels.
