CMS DT muon chambers upgrade — •Daniel Teyssier — III Phys. Inst. A, RWTH 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 components inside the gas volume is very low and there is no need to replace the chambers themselves for HL-LHC. But the increase of the trigger rate and the radiation environment requires an exchange of the on-board electronics in the detector. A new mini crate (MiC) is currently studied in order to keep the minimal functionality inside the detector and transfer the trigger level-1 to the service cavern area, which is accessible at any time in case of replacement of one component. Some longevity studies are also performed using the Gamma Irradiation Facility (GIF++) to simulate three times the HL-LHC equivalent dose. The new MiC will be tested in the same way before to be installed in the experimental cavern.
