摘要
快速实时的亮度监测器将为升级后的北京正负电子对撞机的操作提供很大帮助 .把单韧致辐射过程产生的光子转化为带电粒子 ,收集带电粒子在辐射体中产生的C erenkov光可用来测量亮度 .论文模拟研究了单韧致辐射过程的性质 ,并用GEANT3和GEANT4模拟了亮度测量的整个过程 。
A fast and real time luminosity monitor will be helpful to Beijing Electron Positron Collider (BEPC) after its upgrade. The luminosity can be measured by collecting Cerenkov light induced inside radiator by charged particles which are converted from photons from single Bremsstrahlung radiations. This article explores the properties of the above process and simulates the whole process of luminosity measurement using GEANT3 and GEANT4 software packages. The optimized design parameters are given.
