Description

To fulfill the requirements of the high-luminosity upgrade of the LHC (HL-LHC) CMS is upgrading its Beam Radiation, Instrumentation and Luminosity (BRIL) system which provides real-time and high-precision luminosity determination, beam-timing, beam-loss, beam-induced background (BIB) and neutron and mixed-field radiation environment monitoring. The recent status of this diverse project will be reported, with an emphasis on luminometry that includes the construction of a dedicated detector, the fast beam conditions monitor (FBCM) with Si-pad sensors and a fast triggerless readout, which will operate independently from the central CMS TCDS and DAQ services. Various CMS subsystems' readout will be adapted to provide luminosity information as well. Notably the tracker endcap pixel detector (TEPX) will feature a dedicated readout system for luminosity and BIB monitoring in real time. The independent operation of FBCM and the innermost layer of TEPX from the rest of CMS will be enabled by a dedicated timing and trigger infrastructure. A novel neutron spectrometer has also been recently introduced to the BRIL upgrade project.
