Abstract: The DESY II Test Beam Facility offers electrons with a user-selectable energy from 1–6 GeVprimarily for detector characterisation. TelePix2, an HV-CMOS sensor, is new user-infrastructure atthe test beam facility used as a Region of Interest (ROI) trigger for efficient small prototype testingand a timing plane for ambiguity suppression.Here, timing characterisation results of TelePix2 are presented. A time resolution of𝜎 = 3.75(1) nswas determined at an efficiency above 99% at a depletion voltage of -85 V. Further timing improvementsO(0.1 ns) were achieved through offline corrections for delays dependent on hit position and timewalk. A time resolution of 𝜎 = 2.216(3) ns from the signal of TelePix2 that can be used as atrigger was determined.
