Description

This paper describes an integrated system combining a fluorescence detector and a beam position monitor to be implemented at the soft X-ray beamline of the Taiwan Photon Source (TPS) at the National Synchrotron Radiation Research Center (NSRRC). The system reduces production costs and features a more compact design. The TPS beamline is now in its third phase of development. According to user feedback, the fluorescence imaging design uses rear-side image capture in combination with a beam position monitor. This setup helps reduce stray light interference and improves the signal-to-noise ratio. The beam profile can be verified through image processing. The beam position monitors (BPMs) feature independently adjustable linear shift mechanism. The white beam section uses a coaxial heat dissipation system made of chromium-zirconium-copper alloy. This approach removes the need for brazing, reduces overall costs, and enhances both design and manufacturing efficiency. The BPM opening is adjustable within a range of 0 to 25 mm. The integrated system is expected to be deployed in multiple vacuum sections of the TPS 35A and TPS 43A beamlines in 2025.
