The Timepix4 Beam Telescope

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 $2.3\pm 0.1\hat{\mathrm{I}}¼\mathrm{m}$ and $2.4\pm 0.1\hat{\mathrm{I}}¼\mathrm{m}$ 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 $92\pm 5$~ps. The telescope is extensively described including its data acquisition system and dedicated software as well as the corrections applied to the raw measurements.
