CMS Drift Tube Chambers : Upgrade activities during LHC Long Shutdown II — •Archana Sharma, Thomas Hebbeker, Kerstin Hoepfner, Hans Reithler, and Saranya Ghosh — III. Physikalisches Institut A, RWTH Aachen University

To sustain and extend its discovery potential, the Large Hadron Collider (LHC) will undergo a major upgrade in the coming years, referred to as High Luminosity LHC (HL-LHC), aimed to increase its instantaneous and integrated luminosity respectively by a factor of five and ten beyond the original design value. After delivering an integrated luminosity of more than 160 fb-1 until the end of Run 2, from the beginning of 2019, LHC is shutdown for two years (LS2) in order to get its accelerator-chain and detectors upgraded for the HL-LHC phase. During this LS2, The CMS experiment aims to upgrade its electronics and detector performance to improve the data taking and a precise reconstruction of all the particles in high pile-up conditions of HL-LHC. Drift Tube (DT) chambers as one of the important part of CMS muon system responsible for identifying, measuring and triggering on muons by the precise measurement of their position. This talk briefly summarizes the ongoing activities/plans related to the electronics upgrades of DT chambers along with some details about the gas monitoring in the DT system using Drift Velocity Chambers (VDC).
