Abstract

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 180 GeV/c mixed hadron beam. The pointing resolution at the centre of the telescope is 2.3 ± 0.1 μm and 2.4 ± 0.1 μm in x and y directions, respectively. The temporal resolution for the combined timestamps on a track using only the information from the Timepix4 planes is found to be 92 ± 5 ps. The telescope is extensively described including its data acquisition system and dedicated software as well as the corrections applied to the raw measurements.
