Abstract:
A vertical calibration system with the error of about ±15μm for the newly eight BPMs is described here, which has been developed for the upgrade of the injection system in NSRL phase II project. A data procession to calibrate the BPM and the error calculation methods for fitting of the electric field as well as the calculating result are also presented. A commercial available Bergoz BPM Module, which works on heterodyne receiving with up tp 75dB dynamic range and 1μm resolution, is introduced. With the calibration system and the data procession methods, we have completed the calibration and the inspection of the quality for newly developing eight BPMs.
