摘要
采用Oprea程序对合肥光源200MeV直线加速器束流位置检测器(BPM)的电磁场进行了计算,由2 D的静电场来模拟计算BPM的特性阻抗和耦合系数,采用2 D的静磁场来模拟计算其位置灵敏线性曲线。由此,进行了直线加速器束流位置检测器的优化设计,得到了4个60°电极的位置检测器。它具有非常好的线性,在位置上具有足够大的信号强度,并且较好地满足了直线加速器的几何与机械要求。
In this paper,the electromagnet field of beam position mornitor for 200 MeV LINAC of Hefei Light Source is calculated by program Oprea,2-D electrostatic field computation is used to calculate the characteristic impedance and coupling coefficient,2-D magnetstatic field computations is used to calculate the sensitivity linearity curve of beam position.The optimizing design of beam position mornitor for LINAC has been done,and the design with 4 one-end-shorted 60-degree electrodes is chosen.It provides a very good linearity and sufficient signal power for position measurements,while satisfying the geometrical constrains and mechanical requirements for LINAC.
