Abstract: Superconducting properties of the Nb3Sn material only show up after heat treatment, and during the heat treatment process, the temperature of magnet, the gas pressure and the mass flow rate of gas should be monitored. So based on EPICS, a supervisory control system has been developed, and enterprise-level Web technology is applied to the system. After years of commissioning and operation, the CSMC heat treatment process of Nb3Sn outside and inside coil has been successfully performed.

Key words: Nb3Sn superconducting magnet, CSMC heat treatment, supervisory control system
