Dialing back time on Timepix3: A study on the timing performance of Timepix3
R. Geertsema

TL;DR
This study thoroughly investigates the timing performance of Timepix3 detectors, identifying systematic delays and demonstrating that pixel-level corrections significantly improve time resolution, which is crucial for future 4D tracking in high-energy physics.
Contribution
The paper provides a detailed analysis of Timepix3 timing systematics and introduces correction methods that enhance its time resolution, advancing detector performance understanding.
Findings
Delay differences across pixels can reach 4 ns.
Pixel-level corrections improve time resolution by approximately 159 ps.
Achieved time resolution after correction is 686.4 ps, better than uncorrected data.
Abstract
For the advancement of the understanding of timing systematics in pixelized readout chips and for the benefit of future fast timing detectors to aid 4D tracking technology in the HL-LHC, we have performed detailed studies of the timing properties of the Timepix3, a hybrid pixel detector developed by the Medipix collaboration. These studies use three different measurement techniques to investigate the timing systematics of this detector: test pulses, testbeam, and a laser setup that we build for this work. The average delay over the pixel matrix is determined with the testbeam and the laser and shows the same structure for different Timepix3 chips. The difference in delay results in a maximum difference over the pixel matrix of around 4 ns, which is large compared to the time bins of 1.56 ns. By correcting for this difference on a per-pixel level, the time resolution is on average…
