Abstract :
An automatic calibration system for the beam position monitor (BPM) of the HLS (Hefei Synchrotron Radiation Light Source) storage ring is described. The system integrated a manipulator for holding a simulated antenna vertically to move in horizontal plane, a signal collector and a data processor. The positioning accuracy of an antenna, thin wire, is monitored by a set of microscopes with reading resolution of 0.1 μm. Optical gratings with a veracity of 5 μm give the position of the antenna. The system has been used for the 2nd phase of HLS to calibrate the BPM detectors and measured 4 vacuum chambers, which have been installed in the storage ring. Test results show that the performance of the system is good enough for calibration
