The high-luminosity upgrade of the LHC (HL-LHC) brings unprecedented requirements for precision bunch-by-bunch luminosity measurement and beam-induced background monitoring in real time. A key component of the CMS Beam Radiation Instrumentation and Luminosity detector system is a stand-alone luminometer, the Fast Beam Condition Monitor (FBCM), which is able to operate independently at all times with a triggerless asynchronous readout.

The physics program of the HL-LHC requires high-precision (≲1%) luminosity determination. Two new luminosity detectors are being developed by the CMS BRIL (Beam Radiation, Instrumentation, and Luminosity) project: the Fast Beam Condition Monitor (FBCM), a standalone detector with unique timing capabilities, and the Tracker Endcap Pixel (TEPX) detector augmented with real-time cluster reconstruction in the FPGA of a dedicated back-end board at 10% of the full level-1 trigger rate.

The high-luminosity upgrade of the LHC brings unprecedented requirements for real-time andprecision bunch-by-bunch online luminosity measurement and beam-induced background monitoring. Akey component of the CMS Beam Radiation, Instrumentation and Luminosity system is a stand-aloneluminometer, the Fast Beam Condition Monitor (FBCM), which is fully independent from the CMScentral trigger and data acquisition services and able to operate at all times with a triggerlessreadout.

The Phase-2 CMS BRIL system for precision luminometry
/ Mallows, Sophie (KIT, Karlsruhe, EKP)
/CMS Collaboration
The CMS Beam Radiation, Instrumentation and Luminosity (BRIL) system aims to provide high-precision bunch-by-bunch luminosity determination in the harsh conditions of the High-Luminosity LHC. Luminosity instrumentation will use diverse technologies, including a dedicated detector, the fast beam conditions monitor (FBCM) with Si-pad sensors and a fast triggerless readout. [...]

This contribution presents a novel single-moderator neutron spectrometer, named “TetraBall”, developed at INFN and optimized for characterizing the neutron field in the CMS experimental cavern. The TetraBall condenses the functionality of several Bonner Spheres (BS) in a single moderator and it is equipped with 42 SiC radiation-hard detectors organized in a tetrahedral geometry designed to be insensitive to incident gammas and charged particles.
