Design and commissioning of a temperature-controlled readout station for CMS 2S modules — Christian Dziwok1, Lutz Feld2, Katja Klein2, Alexander Pauls2, Oliver Pooth1, Marius Preuten2, Max Rauch2, •Nick Thamm1, and Tim Ziemons1 — 1III.

During the high luminosity upgrade of the LHC starting in 2024, the CMS experiment gets partly replaced in the Phase-2 Upgrade. Part of this upgrade is the Outer Tracker, which gets exchanged to contribute to the L1-trigger system. The new detector consists of 2S, featuring two strip sensors, and PS silicon modules, which feature one strip and one macro-pixel sensor. These modules get cooled by CO2 phase-change cooling loops to approximately -30∘C to ensure operation while being irradiated. All one thousand modules build by the RWTH Aachen University will be quality controlled, including functionality tests under nominal conditions.
This talk focuses on the design and commissioning of a readout station, which is used to test single modules at operational temperature during prototyping.
