CMS DT system electronics upgrade and verification — •Dmitry Eliseev, Thomas Hebbeker, Kerstin Hoepfner, Carsten Heidemann, Giovanni Mocellin, Henning Keller, and Archie Sharma — III. Physikalisches Institut A. RWTH Aachen University, Aachen

The Drift Tube (DT) system is the key detector in the region of the CMS barrel dedicated to the measurement of muon tracks. The signals from a huge number of the DT chambers must be acquired fast and synchronously in order to deliver the information about the hits. In the context of increasing the luminosity of the LHC in preparation for the Phase II the DT system is being upgraded. The main focus of this upgrade is the development of a new generation of read out electronics based on the FPGA technology. The new electronics will provide for the DT system higher acquisition rates, radiation resistance and flexibility of the trigger settings. The development of the new generation instrumentation requires numerous verification measurements. For these purposes a cosmic muon test stand is currently being redesigned and improved at RWTH Aachen. This test stand combines different types of detector technologies providing redundancy and therefore turning it to an excellent verification facility for the new generation electronics of the DT system. This talk presents the status of the DT system upgrade with the main focus on the upgrade of the read out electronics and gives the overview of the Aachen cosmic muon test stand.
