Description
Taiwan Photon Source (TPS), a 3 GeV synchrotron radiation facility located at the National Synchrotron Radiation Research Center (NSRRC), comprises a linear accelerator, a booster synchrotron, and a storage ring. Accurate measurement and adjustment of the electron bunch phase are required to maintain electron beam stability. A phase measurement system utilizing the I/Q demodulator approach to calculate the beam phase has been developed and installed at TPS, providing preliminary results.
However, uncalibrated operation revealed that the system's accuracy is degraded by measurement errors arising from gain and quadrature imbalance in the I/Q outputs.This paper describes the effort to resolve the I/Q system errors. We present the methodology for measuring the uncalibrated I/Q errors and detail the calibration scheme implemented to correct these systematic inaccuracies. Furthermore, this paper introduces the resulting measurement data, demonstrating the improved accuracy achieved through I/Q error correction.
