Magnetic measurement system for cooling storage ring of heavy ion research facility in Lanzhou

Magnetic measurement system is an indispensable part of National Scientific Major-project Cooling Storage Ring of Heavy Ion Research Facility in Lanzhou (HIRFL-CSR). Three measurement systems, Hall probe mapping, integral coils and harmonic coils system were developed. The structure and parameters of main devices were described in details in the paper. And the manufacturing technics and the checking results were also involved. By means of a long time repeat testing, it is proved that the repeatability and stability of the systems match the requirements of CSR. The systems are applying in CSR project now. (author)
