Abstract

The in-vacuum undulator (IVU) controller has been developed and applied in Shanghai Synchrotron Radiation Facility (SSRF), China. The controller based on programmable logic controller (PLC) mainly controls two stepper motors for regulating the gap and taper of magnet array, implement automatic control of the correction coil power supplies, etc. In addition, the controller is also provided with a local and remote working mode. This paper mainly introduces related hardware and software design for the IVU controller.
