	Taiwan Photon Source (TPS) is a 3 GeV synchrotron light source which is in construction at NSRRC. Latest generation BPM electronics with FPGA enhanced functionality of current generation products was adopted. The prototype is under testing. To achieve its design goal of the TPS and eliminate beam motions due to various perturbation sources, orbit feedback is designed with integration of BPM and corrector control system . The design and implementation of the BPM system will be summarized in this report.

	The TPS (Taiwan Photon Source) is the latest generation of 3 GeV synchrotron light source which has been in construction since 2010. The EPICS framework is adopted as control system infrastructure for the TPS. The EPICS IOCs (Input Output Controller) and various database records have been gradually implemented to control and monitor each subsystem of TPS. The subsystem includes timing, power supply, motion controller, miscellaneous Ethernet-compliant devices etc. Through EPICS PVs (Process Variables) channel access, remote access I/O data via Ethernet interface can be observed by the useable graphical toolkits, such as the EDM (Extensible Display Manager) and MATLAB. The operation interface mainly includes the function of setting, reading, save, restore and etc. Integration of operation interfaces will depend upon properties of each subsystem. In addition, the centralized management method is utilized to serve every client from file servers in order to maintain consistent versions of related EPICS files. The efforts will be summarized in this report.

	The Taiwan Photon Source (TPS) is a low-emittance 3-GeV synchrotron light source which is in construction on the National Synchrotron Radiation Research Center (NSRRC) campus. The control system for the TPS is based upon EPICS framework. The standard hardware and software components have been defined. The prototype of various subsystems is on going. The event based timing system has been adopted. The power supply control interface accompanied with orbit feedback support have also been defined. The machine protection system is in design phase. Integration with the linear accelerator system which are installed and commissioned at temporary site for acceptance test has already been done. The interface to various systems is still on going. The infrastructures of high level and low level software are on going. Progress will be summarized in the report.

	The Taiwan Photon Source (TPS) is a latest generation synchrotron light source. Stringent power supply specifications should be met to achieve design goals of the TPS. High precision power supply equipped with 20, 18, and 16 bits DAC for the storage ring dipole, quadrupole, and sextupole are equipped with Ethernet interfaces. Control interface include basic functionality and some advanced features which are useful for performance monitoring and post-mortem diagnostics. Power supply of these categories can be accessed by EPICS IOCs. The corrector power supplies' control interface is a specially designed embedded interface module which will be mounted on the corrector power supply cages to achieve required performance. The setting reference of the corrector power supply is generated by 20 bits DAC and readback is done by 24 bits ADC. The interface module has embedded EPICS IOC for slow control. Fast setting ports are also supported by the internal FPGA for orbit feedback supports.

	The timing system of the Taiwan Photon Source provides synchronization for electron gun, modulators of linac, pulse magnet power supplies, booster power supply ramp, bucket addressing of storage ring, diagnostic equipments, beamline gating signal for top-up injection. The system is based on an event distribution system that broadcasts the timing events over a optic fiber network, and decodes and processes them at the timing event receivers. The system supports uplink functionality which will be used for the fast interlock system to distribute signals like beam dump and post-mortem trigger with 10 μsec response time. The hardware of the event system is a new design that is based on 6U CompactPCI form factor. This paper describes the technical solution, the functionality of the system and some applications that are based on the timing system.
