Control system for the superconducting insertion devices of NSRRC

To enhance hard X-ray production in the 1.5 GeV storage ring of NSRRC to serve the rapidly growing X-ray user community in Taiwan, the storage ring are planed to install up to five superconducting insertion devices. A 6 Tesla superconducting wavelength shifter was installed in mid-2002. A 3.2 Tesla superconducting multipole wiggler will be installed in the fall of 2003. The project for the other three multipole wigglers is launched. The control system had been implemented to support the operation of the superconducting insertion devices. The control system play a role to coordinate the operation of the main power supply and the trimming power supplies to charge/discharge the magnet and provide interlock protection for the magnet coils and vacuum ducts. A friendly user interface and various application programs are used to support routine operation. Design considerations and details of the implementation are also presented.
