摘要
Belle II实验将成为间接搜索非标准模型物理的前沿，利用SuperKEKB对撞机在高强度10 GeV正电子碰撞中产生的数十亿重夸克和$\ τ $轻子。达到所需精度所需的强光束与可能损坏内部探测器的高光束背景辐射有关。基于人造金刚石传感器的专用辐射监测和波束中止系统确保了保护和安全的数据采集条件。我简要概述了该系统，并说明了2019年物理操作中的操作经验和性能。
Diamond Detectors for Radiation Monitoring and Beam Abort at Belle II
The Belle II experiment will be at the forefront of indirect searches for non-Standard-Model physics using billions of heavy quarks and $\tau$ leptons produced in high-intensity 10 GeV electron-positron collisions from the SuperKEKB collider. The intense beams needed to achieve the required precisions are associated with high beam-background radiation that may damage the inner detectors. A dedicated radiation-monitoring and beam-abort system, based on artificial diamond sensors, ensures protection and safe data taking conditions. I briefly outline the system and illustrate the operational experience and performance during 2019 physics operations.
