Upgrade of the MDT Front-end Electronics of the LMU Cosmic Ray Facility — •Eshita Kumar, Otmar Biebel, Valerio D'Amico, Stefanie Götz, Daniel Grewe, Ralf Hertenberger, Nirmal Mathew, Nick Schneider, Chrysostomos Valderanis, and Fabian Vogel — LMU München

As part of the Phase-II Upgrade of the ATLAS Muon Spectrometer for the High Luminosity LHC (HL-LHC), a new and enhanced trigger and readout system for the Monitored Drift Tube (MDT) chambers is being installed. To evaluate the Phase-II upgrades on an MDT chamber outside the ATLAS detector and independently of ongoing upgrade activities at CERN, the LMU Cosmic Ray Facility (CRF) in Garching serves as an ideal testing site. Equipped with two fully operational MDT chambers and scintillators for triggering, the facility has been upgraded with Phase-II front-end electronics to facilitate a comprehensive test. These new front-end electronics are tested using the MiniDAQ readout system. In this talk, the current status of the project and first results will be shown. A comparison between the performance of the original CRF electronics and the new Phase-II electronics will be presented.
