TL;DR
The Timepix particle tracking telescope, developed for LHCb VELO upgrade, offers high-resolution, high-rate particle tracking with efficient charge and timing measurements, supporting sensor development and testing at CERN.
Contribution
This paper introduces a high-performance particle tracking telescope based on Timepix ASICs, optimized for high rate and precise timing, supporting LHC detector upgrades.
Findings
Reconstructed track rates of 3.5 to 7.5 kHz during beam spills.
Timing resolution of 1 ns with over 98% efficiency.
Pointing resolution of 1.6 micrometers at the center of the telescope.
Abstract
The Timepix particle tracking telescope has been developed as part of the LHCb VELO Upgrade project, supported by the Medipix Collaboration and the AIDA framework. It is a primary piece of infrastructure for the VELO Upgrade project and is being used for the development of new sensors and front end technologies for several upcoming LHC trackers and vertexing systems. The telescope is designed around the dual capability of the Timepix ASICs to provide information about either the deposited charge or the timing information from tracks traversing the 14 x 14mm matrix of 55 x 55 um pixels. The rate of reconstructed tracks available is optimised by taking advantage of the shutter driven readout architecture of the Timepix chip, operated with existing readout systems. Results of tests conducted in the SPS North Area beam facility at CERN show that the telescope typically provides…
