Description
The CMS Muon system is undergoing significant upgrades in preparation of the High-Luminosity LHC (HL-LHC) operation, in order to maintain excellent performance in unprecedented collision rates. The electronics of the Cathode Strip Chambers (CSCs) are therefore being upgraded, and the new complementary Gas Electron Multiplier (GEM) detectors are being installed. One of the new GEM stations, GE1/1, was already installed next to the most forward CSCs (ME1/1). In addition, the GE2/1 station will be installed next to the ME2/1 CSCs. Combining the information of neighbouring CSCs and GEMs will improve the muon triggering efficiency.
This talk will cover the recent developments for the CSC upgrade, modifying the trigger boards and operating a demonstrator in CMS, as well as the progress integrating GEM and CSC data into one trigger algorithm. The performance of the existing GEM-CSC trigger for GE1/1 and ME1/1 is also discussed.
