Bluesky-based fluorescence mapping technology
“The control and data acquisition system of the Shanghai Light Source Hard X-ray Micro Focusing Beam Line Station were developed in the EPICS environment, but the fluorescence scanning system based on EPICS software cannot meet some specific requirements for fluorescence surface scanning experiments. For this, a method combining Bluesky and EPICS software was adopted, and a control and data acquisition system was designed based on Python syntax structure. The system integrates motion control, light intensity detection, and fluorescence signal acquisition functions, realizing real-time display of data tables, drawing of fluorescence spectra, adaptive step scanning and automatic calculation of peak data, continuous scanning of multiple arbitrary position samples, and two-dimensional square spiral scanning and other fluorescence surface scanning related technologies. This system enables users to complete complex fluorescence surface scanning with simple operations, improving experimental flexibility and efficiency.”
