Integration of an SiPM-Based Scintillation Detector into the Readout Chain of a Cosmic Muon Test Stand with a CMS Drift Tube Chamber — Erik Ehlert, Dmitry Eliseev, •Nils Jonathan Esper, Thomas Hebbeker, Kerstin Hoepfner, Markus Merschmeyer, Carsten Presser, and Alexander Schmidt — III. Physikalisches Institut A, RWTH Aachen University

The III. Physics Institute A at RWTH Aachen University operates a cosmic test stand with a fully functional Drift Tube (DT) chamber and all necessary peripherals, which is similar to the chambers used in the Compact Muon Solenoid (CMS) experiment. Recently, the chamber was equipped and recommissioned with the readout electronics that will be used in the Phase-2 upgrade of CMS. In addition, a scintillation detector with Silicon Photomultiplier (SiPM) readout has been constructed at our institute. With the goal of integrating the readout of the scintillator into the chamber backend system, new electronics and corresponding firmware have been developed. These electronics feature the Low Power Gigabit Transceiver (lpGBT) chip, a serializer-deserializer device developed at CERN. It allows to inject the detector data into the backend system, and maintains synchronization with the global clock. This talk presents the newly developed scintillator readout chain and first recorded data. The data is compared to the independently reconstructed tracks from the DT chamber.
