CMS DT muon chambers upgrade — •Carsten Heidemann, Thomas Hebbeker, Markus Merschmeyer, and Daniel Teyssier — III. Physikalisches Institut A RWTH Aachen University, Aachen

The CMS Drift Tubes (DT) muon chambers in the barrel will cope with higher pile-up as well as higher background conditions in the next High Luminosity (HL) LHC program. The failure rate of the detector itself is very low and there is no need to replace the chambers themselves for HL-LHC. The increased trigger rates and the radiation environment requires an exchange of the frontend electronics mounted on the chambers. A new mini crate (MiC2) is currently designed to replace the old electronics and move the level-1 trigger functionality to the better accessible service cavern. The longevity studies of the chambers are ongoing using the Gamma Irradiation Facility (GIF++) to re-enact the conditions of three times the HL-LHC equivalent dose.
