Photon beam position monitor signal processing system with logarithmic ratio method

  • A photon beam position monitor signal processing system with logarithmic ratio method was designed for two-wire monitor in the machine diagnostic beamline(MDBL) at Hefei Light Source(HLS). A current-voltage converter was designed which is capable of measuring current value from 0.1 nA to 3.5 mA using LOG112 chip. The resolution of the photon beam position monitor is about 1 μm in MDBL, and the linearity range is more than ±3 mm. The system has a good performance price ratio.
