Description
Two sets of blade-type X-ray beam position monitors (XBPMs) are installed in the front end of Taiwan Photon Source (TPS), with the downstream monitor designated as XBPM2. Significant challenges in the calibration and operation of XBPM2 in the TPS front end have been primarily attributed to the upstream mask aperture size being nearly identical to the blade tip spacing. It leads to a restricted effective horizontal linear region and results in discrepancies between Kx and Ky, thereby increasing horizontal measurement error. By enlarging the upstream mask aperture, a significant improvement in the performance of XBPM2 was observed, and the detailed results will be presented in this paper.
