Descripción
The CMS experiment at the Large Hadron Collider (LHC ) faces its High Luminosity fase (HL-LHC) with an ambitious detector upgrade program. CIEMAT's group activities focus on the Barrel Muon Drift Tubes (DT) subdetector electronics, which will be completely replaced to operate during HL-LHC. The upgraded architecture ships via optical links (lpGBT, VTRX+) all signals to the backend, where complex logic will run in FPGAs providing a precision matching the maximum chamber resolution. In this project CIEMAT makes hardware contributions in the full chain both at the frontend and backed.
This contribution will focus on the frontend part, where CIEMAT has designed the OBDtheta board, a 228 channels TDC readout mounting radiation tolerant flashbases PolaFire Microsemi FPGA and CERN's VTRX+ optics on a 14 layers halogen-free material PCB. The production of 180 boards (plus spares) is ongoing and will pass quality control at CIEMAT in the coming months. CIEMAT is also producing mechanics to cool, protect and support these electronics, as well as electronics and mechanics components for the CMS High Granualarity Calorimeter that will replace current endcap calorimeters. The status of these activities will be also reported.
