Abstract：
Beam-based BPM offset calibration was carried out for Injector Ⅱ at the C-ADS demonstration facility at the Institute of Modern Physics (IMP), Chinese Academy of Science (CAS). By using the steering coils integrated in the quadrupoles, the beam orbit can be effectively adjusted and BPM positions recorded at the Medium Energy Beam Transport of the Injector Ⅱ Linac. The studies were done with a 2 mA, 2.1 MeV proton beam in pulsed mode. During the studies, the "null comparison method" was applied for the calibration. This method is less sensitive to errors compared with the traditional transmission matrix method. In addition, the quadrupole magnet's center can also be calibrated with this method.
