摘要

升级后的大型强子对撞机(LHCb)探测器将提供Run3在质子-质子碰撞的瞬时光度增加到2⋅1033 cm-2s-1，能量高达14 TeV时采集的数据。为了保证实验的安全运行，建立了新的束流和本底辐射监测系统(RMS-R3)。RMS-R3基于乌克兰国家科学院核研究所(基辅，乌克兰)开发的金属箔探测器技术。该系统由四个检测模块组成，每个模块中有两个传感器。它们的频率响应与入射带电粒子的通量成正比。模块位于梁管周围，距离相互作用点2.2米。2022年第3次运行测试结果证明了该系统运行可靠。应用不对称方法，获得了高精度的相互作用区域定位和光束和背景贡献数据。

RMS-R3 – the system for monitoring the region of interactions and background at the LHCB experiment (CERN)

The upgraded Large Hadron Collider beauty (LHCb) detector will provide data taken in Run3 at the instantaneous luminosity of proton-proton collisions increased to 2⋅1033 cm-2s-1 at energies of up to 14 TeV. To ensure the safe operation of the experiment, a new beam and background Radiation Monitoring System (RMS-R3) was built. RMS-R3 is based on metal-foil detector technology developed at the Institute for Nuclear Research, National Academy of Sciences of Ukraine (Kyiv, Ukraine). The system comprises four detector modules with two sensors in each. Their frequency response is proportional to the flux of incident charged particles. The modules are located around the beam pipe at a distance of 2.2 m from the interaction point. The results measured during the Run3 in 2022 testify to the reliable operation of the system. Applying the asymmetry method, high-accuracy data were obtained on the localization of the interactions region and the beam and background contribution.
