An automated HAXPES measurement system with user-friendly GUI for R4000-10 keV at BL46XU in SPring-8

Abstract

We have developed a noble HAXPES measurement system, where the controls for sample manipulation and VG Scienta R4000 work together. The main part of the system is developed by spec. R4000 is controlled by sending commands from spec to the TCP server programed by LabVIEW with SESWrapper library. The command line interface of spec is wrapped by a graphical user interface (GUI) which can be easily operated by users. The sample can be aligned in the intuitive way by clicking the position to be measured on the sample image. Fine alignment can be done by scanning the sample position to maximize the count rate of photoelectrons. After setting measurement positions and conditions on the GUI, the automatic measurements through the multiple measurement positions can be performed in this system.
