Integrated Commissioning Test of the Safety System for JT-60SA Superconducting Magnets Developing Vacuum Monitoring and Safety Control Systems
The safety system for JT-60SA superconducting magnet was developed for 1） signal processing of quench detectors; 2） protecting superconducting components, including magnet, thermal shield, feeder, and high temperature superconducting current lead; and 3） transmitting protection interlock signals as well as protecting operation data. This paper introduces the safety system functions. Based on the magnet systemʼs withstand voltage performance in a vacuum condition, a vacuum pressure monitoring system is essential to protect the superconducting magnet system from insulation incidents. A vacuum monitoring system has been developed, and response time has been measured when the vacuum is degraded. The response time characteristics of the vacuum monitoring system are reported.
