Commissioning and Time Resolution Studies of a Timepix3 Tracking Plane in the DESY II test beam facility — •Keerthi Nakkalil¹, Annika Vauth^2,3, Ingrid Gregor^4,1, and Simon Spannagel⁵ — ¹University of Bonn, Bonn, Germany — ²DESY, Hamburg, Germany — ³University of Hamburg, Germany — ⁴DESY, Hamburg, Germany — ⁵DESY, Hamburg, Germany

Test beam infrastructure plays an indispensable role in the R&D and prototyping of key detector technologies. At the DESY II test beam facility, the EUDET-telescopes based on the Mimosa26 monolithic active pixel sensors (MAPS) has been a workhorse for detector developments providing unparalleled tracking resolution for the test beams for over a decade. Our goal is to integrate Timepix3 tracking planes into the existing telescope at the DESY II test beam facility to perform track time-stamping at the nanosecond scale.

In this talk, the results of the studies undertaken to understand the general characteristics of the Timepix3 ASIC such as noise performance, threshold, and gain dispersion will be presented. Furthermore, the tracking resolution studies performed at the test beam facility will also be shown.
