摘要

在上海光源BL14W1线站，成功搭建一套基于LabVIEW的高能量分辨谱仪运动控制和数据采集系统，该光谱仪系统可以实现高能量分辨荧光探测X射线吸收谱（High Energy Resolution Fluorescence Detected X-ray Absorption Spectroscopy，HERFD-XAS）、X射线发射谱（X-ray Emission Spectroscopy，XES）和共振X射线发射谱（Resonant X-ray Emission Spectroscopy，RXES）等主要实验功能，分辨率达到亚电子伏。硬件系统采用上海光源统一的VME运动控制硬件系统和硅漂移固体探测器；软件系统采用LabVIEW编写用户操作界面，利用DSC（Data logging and Supervisory Control Module）模块实现与运动控制使用的实验与物理工业控制系统（Experimental and Physics Industrial Control System，EPICS）系统的数据交换。利用基于该运动控制和数据采集系统的光谱仪，开展了Mn化合物和ThO

锕系化合物的实验。结果表明，该系统可以满足高能量分辨率实验的需求。

Abstract

Background

High energy resolution spectrometer can perform high energy resolution fluorescence detected X-ray absorption spectroscopy (HERFD-XAS)

X-ray emission spectroscopy (XES)

resonant X-ray emission spectroscopy (RXES)

and other experiments. The energy resolution could be sub-eV level and the system can get more fine electronic structure information compared with the conventional spectral experimental methods.

Purpose

This study aims to develop a data acquisition system of high energy resolution spectrometer based on LabVIEW at BL14W1 X-ray absorption fine structure (XAFS) station in Shanghai synchrotron radiation facility (SSRF).

Methods

The hardware system includes two parts:VME motion control system for multi-dimension adjusting and silicon drift detector (SDD) fluorescence detector. The software architecture of the spectrometer consists of two parts

the experimental and physics industrial control system (EPICS) for motor control system and LabVIEW for data acquisition system (DAQ). LabVIEW's data logging and supervisory control (DSC) module is used for data exchange between the motion control system and the DAQ.

Results

The energy resolution of this spectrometer is 0.5 eV

which can distinguish different compounds in the mixture.

Conclusion

It is proved by experiment that the energy resolution and counting rate of this high energy resolution spectrometer has reached the level of the same kind of devices in the world.
