Description

During the 2024 and 2025 LHC proton-proton runs, the LHCb experiment, following its upgrade, achieved a substantial increase in delivered luminosity compared to previous years, exceeding the level of 10 fb-1 per year. While this enhancement greatly expands LHCb’s physics reach, it also leads to a marked rise in radiation levels in the experimental insertion region, originally designed for a significantly lower luminosity target.
Throughout the 2024 p-p operation, several failures of electronic racks and cryogenic sensors, mostly attributed to single-event effects (SEEs), were observed around the LHCb cavern and caused tens of hours of LHC downtime.
This work presents a benchmarking of dedicated FLUKA simulations, used to quantify the radiation levels and identify possible mitigation measures, against measurements by the Battery Radiation Monitors (BatMons). The study guided the relocation of sensitive equipment and the installation of additional shielding in specific underground areas hosting critical electronics, effectively reducing radiation exposure during the remainder of Run-3. Finally, possible improvements for shielding are also discussed in view of Run-4.
