Abstract
Insertion device (ID) is a crucial component in thirdgeneration synchrotron light sources, which can produces highly-brilliant, forward-directed and quasimonochromatic radiation over a broad energy range for various experiments. In the phase I of the Taiwan Photon Source (TPS) project, two EPU48s (Elliptically Polarized Undulator) will be installed. The control system for EPU48 is based on the EPICS architecture. All control functionality coordinate by the cPCI EPICS IOC. The main control components include the motor with encoder for gap adjustment and phase moving, trimming power supply for corrector magnets, temperature sensors for ID environmental monitoring , interlock system (limit switches, tilt sensor, emergency button) for safety and supporting of on-the-fly experiments for beamline. Features and benefits of EPU48 control system will be summarized in this report.
