Magnetic Field Measurement System of the BRing Fast Ramping Dipole Magnet in HIAF

The fast-ramping dipole magnet's performance indices, test specifications, and measurement techniques of BRing in HIAF project are presented, and the components of the fast-ramping dipole magnet steady-state magnetic field measurement system and dynamic magnetic field measurement system are described. In the steady-state magnetic field measurement, the on fly measurement technique is adopted for the long coil measurement system to improve the integrated magnetic field measurement accuracy and test efficiency. In the dynamic magnetic field measurement, the matrix coil for magnetic field delay and magnetic field distortion measurement is developed. Through the testing of the magnet prototype, the performance index verification of the test system and steady-state magnetic field measurement of the prototype magnet are completed. Based on the test data, the secondary trimming of the magnet is completed.
