在北京正负电子对撞机上首次从粒子物理实验的需要出发开展了对撞区辐射本底的系统研究,发展了动态研究对撞区辐射水平的有效方法,能够灵敏地反映出对撞机不同工作状态下的本底辐射水平与其分布情况以及在对撞状态下随时间变化的规律,考察了国产BGO及BaF_2晶体在对撞机辐射环境中的抗辐照性能。
For the first time, a systematic study of the radiation background in the colliding area was conducted based on the needs of particle physics experiments at Beijing Electron-Positron Collider. The effective method of dynamically studying the radiation level of the colliding area was developed, which can sensitively reflect the difference between collider Under the working condition of the background radiation levels and their distribution as well as the state of the collision with time changes over time, investigated the domestic BGO and BaF 2 crystals in the collider radiation environment anti-radiation performance.
