| 摘 要： | 法拉第杯是加速器束流强度绝对测量装置，其收集效率对于法拉第杯的设计至关重要。应用蒙特卡罗软件FLUKA对北京正负电子对撞机直线加速器分析磁铁AM2处的法拉第杯进行模拟设计。给出了法拉第杯不同部位对收集效率的影响曲线，并给出了入射电子在法拉第杯中的能量沉积分布与带电粒子分布图，最终得到了优化的法拉第杯尺寸，使得对入射电子的收集效率达到99.73%。

| Abstract: | A Faraday cup is an absolute measuring equipment used to measure the accelerator beam intensity, so the calculation of the collection efficiency is of the utmost importance. The Monte Carlo simulation is one of the important methods for simulating the particle transport process and analyzing the energy deposition. A Faraday cup to be installed around the analysis magnet AM2 in the linac of BEPCII, was simulated using the Monte Carlo program, FLUKA. The curves of collection efficiency vs the different parts of Faraday cup structure were obtained, the energy deposition distribution and the charged particle distribution of the incident electrons were also simulated, and finally the optimization designed size of the Faraday cup was given. |
