Beam test of 2S module prototypes for the Phase-2 CMS Outer Tracker — Christian Dziwok2, Lutz Feld1, Katja Klein1, Martin Lipinski1, Alexander Pauls1, Oliver Pooth2, Nicolas Röwert1, and •Tim Ziemons2 — 1I. Physikalisches Institut B, RWTH Aachen University — 2RWTH Aachen University - Physics Institute III B, Aachen, Germany
The CMS detector will be upgraded in the Phase-2 Upgrade for the operation at the HL-LHC. Among others, the silicon tracking system will be completely replaced by a new system providing an extended acceptance, an improved granularity and the feature to include tracking information into the level-1 trigger. The new Outer Tracker will consist of 2S modules with two strip sensors and PS modules with a macro-pixel sensor and a strip sensor, specialized detector modules with onboard pT discrimination.
The functionality of current generation prototype 2S modules has been tested at the test beam facility at DESY Hamburg in November 2019. With a 4 GeV electron beam, various studies are performed like efficiency scans at different positions of the module or at varying inclination angles to mimic different pT particles. In this talk, efficiency studies are presented.
