Abstract
The Insertion devices (ID) for Taiwan Photon Source are under construction. There are eight insertion devices under construction. These devices include in-vacuum undulators (IU) with or without taper, elliptically polarized undulators (EPU). Control framework for all IDs was developed. Using common hardware and software components are as possible. Motion control functionality for gap and phase adjustment supports servo motors, stepper motors, absolute encoders, and protection. The motion control system for all IDs is based on the EPICS (Experimental Physics and Industrial Control System) architecture. Trimming power supply for corrector magnets and phase shifter control functionality are also addressed. Miscellaneous controls include ion pumpers and BA gauges for vacuum system, temperature sensors for ID environmental monitoring and baking, limit switches, emergency button. User interface for ID beam line users are included to help them to do experiment, such as ID gap control and on-the fly experimental. The efforts of IDs motion control system will be summarized in the report.
