Description
At the Large Hadron Collider, the experiments sensitive detector components are at risk of being damaged during adverse beam conditions. Thus, the beam-induced backgrounds are closely monitored at multiple locations at the collider. At the LHCb experiment, a Beam Conditions Monitor (BCM) is mounted around the beam pipe at two stations, upstream and downstream of the interaction point. It is built of eight polycrystalline diamond sensors per station and integrated into the LHC Beam Interlock System to trigger beam dumps if unsafe beam conditions are detected. The BCM system has operated reliably during Runs 1 and 2 of the LHC. During the Long Shutdown 2, the LHCb detector underwent a major upgrade to maintain its performance in Run 3 at a fivefold instantaneous luminosity with respect to Run 2. Within this upgrade, the BCM was equipped with new diamond sensors and a new FPGA-based readout system. Additionally, the mechanical support of the BCM upstream station was adjusted to make space for the installation of the PLUME luminometer. This talk gives an overview of the upgraded BCM detector and its performance during Run 3 operation until 2025.
