ECR离子源束流发射度测量系统设计

摘要

为了实现ECR离子源束流发射度的精确、可靠测量,同时实现将系统中不同设备的控制测量数据统一显示到操作界面,基于EPICS软件系统,开发完成了双狭缝电机运动控制和PXI板卡的数据采集的发射度测量系统.采用LabVIEW软件的DSC模块实现对束流流强的PV变量发布;基于StreamDe-vice开发了电机运动控制IOC程序.整套系统运行稳定可靠、使用方便,满足离子源束流发射度的测量要求.%In order to measure beam emittance of ECR ion source more accurately and reliably,and to display data from different devices on the operation interface uniformly,the double slit motor motion control and the da-ta acquisition of PXI board are introduced in the emittance measurement system,based on EPICS software sys-tem.DSC module of LabVIEW is used to achieve the PV release for beam current and StreamDevice is the plat -form for developing IOC program of motor control.
