研制了合肥光源波荡器光束线刀片型光位置检测器.在不同波荡器狭缝下,对刀片电极的光电流进行了测量,并对其进行了标定,得到了灵敏度和同步光中心位置,如在狭缝为40 mm时,水平方向和垂直方向的灵敏度分别为0.001 5 mm~(-1)和0.852 2 mm~(-1).为了改进刀片型光位置检测器,给出了一种交错刀片型光位置检测器的设计,该检测器将狭缝为40 mm时的水平灵敏度提高到0.551 mm~(-1).

This paper describes the development of blade-type photon beam position monitor in undulator beamline at HLS (Hefei Light Source) and the photon beam position measurement system. For different gaps of undulator, the calibration of the monitor was carried out. The sensitivity and center positions of photon beam position monitor were measured for different gaps, for example, the horizontal sensitivity and vertical sensitivity are 0.001 5 mm~(-1) and 0.852 2 mm~(-1) at 40 mm gap. In order to improve the photon beam position monitor, a staggered blade-type photon beam position monitor was introduced. At 40 mm gap, the horizontal sensitivity of the new monitor is 0.551 mm~(-1).
