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.
