Development of EPICS Applications for the Taiwan Light Source

The TLS (Taiwan Light Source) is a third generation of synchrotron light source, and it has been operated since 1993. The TLS control system is a proprietary design. It was performed minor upgrade several times to avoid obsolete of some system components and keep up-to-date during last two decades. The control system of the TPS project (Taiwan Photon Source) is based upon the EPICS framework. To save resources for TLS control system maintenance, adopt EPICS for newly developed and rejuvenated subsystems for some of the TLS control interfaces includes BPM system, insertion devices, bunch-by-bunch feedbacks, electronics instruments interface and so on. Some EPICS related applications have been developed, and EPICS graphical user interface is also operated at the TLS control consoles environment normally. Current system allowed two kinds of control environments working together. The efforts will be described at this report.
