基于LabVIEW的软X射线磁性圆二色实验站反馈控制系统研制

Feedback Control System for Soft X-ray Magnetic Circular Dichroism Experimental Station Based on LabVIEW

本文给出了用一种业界领先的工业标准图形化编程工具LabVIEW来实现国家同步辐射实验室软X射线磁性圆二色实验站高电压反馈控制系统的方法。在实验要求测量的波长范围内,使照射在样品上的流强稳定度得到提高,为分析样品吸收谱提供了很好的基准。与此同时,用LabVIEW建立的系统友好的用户界面,以及其强大、方便的接口指令很好地实现了对常见接口的控制和数据存储,这些对于面向全国用户的国家同步辐射实验室也是很重要的。

A feedback control system was developed for soft X-ray magnetic circular dichroism experimental station based on LabVIEW. By implementing the system, the stability of current through the sample was improved to provide a good criterion for absorption spectrum analysis. The friendly user interface, flexible interface instruction and strong data storage function are also important for National Synchrotron Radiation Laboratory which is open to users from all over the country.
