TelePix2: A HV-CMOS pixel sensor for Fast Timing and Region of Interest Triggering — •Arianna Wintle1, Andre Schöning2, David Immig2, Felix Sefkow1, Heiko Augustin2, Ivan Peric3, Lennart Huth1, Lucas Dittmann2, Marcel Stanitzki1, and Ruben Kolb2 — 1Deutsches Elektronen-Synchrotron — 2Heidelberg University — 3The Karlsruhe Institute of Technology
The DESY II Test Beam Facility offers electrons with a user selectable momentum from 1-6 GeV primarily for detector characterisation. TelePix2, a HV-CMOS sensor, is the latest new user infrastructure at the test beam facility used as an arbitrary Region of Interest (ROI) trigger and a timing plane, for efficient small prototype testing and ambiguity suppression.
This contribution will highlight the importance of TelePix2 in the context of user operation at the test beam facility whilst providing an insight into test beam user infrastructure. The latest performance metrics of TelePix2 including an efficiency above 99 %, a timestamp resolution below 4 ns, and a ROI trigger time resolution below 2.5 ns will be presented.
