Abstract :
Total of 920 steering magnets for KEK B-Factory have been measured by the microcomputer controlled measurement system at IHEP. It took more than two years. During this period, two reference magnets were measured many times. The reproducibility for the reference magnets is better than 8×10-4. This system was used to measure magnets for BEPC (Beijing Electron Positron Collider) ten years ago. It has been improved and updated to meet the new requirements. This paper will cover the details of the measurement system devices, method as well as results
