Abstract: (IOP)
The electronics of the CMS Drift Tubes (DT) chambers will be replaced to operate during High Luminosity (HL-LHC). In the upgraded architecture, optical links (lpGBT, VTRX+) send all signals to the backend, where complex logic running on FPGAs will process the data within trigger latency with precision enough to profit from the full chamber resolution, which in the present system is only possible offline. One of the sixty sectors of the detector was instrumented with the final version of the front-end boards (OBDTs, in two types) during the Winter stop 2022–23. After commissioning and integrating this setup in CMS operations during 2023, its stability has been tested in 2024 LHC collisions. Performance during 2024 campaign is summarized.
