  Timing system for the Taiwan Photon Source (TPS) were setup and ready for accelerator system commissioning. Event based timing system was chosen to satisfy various requirements for the machine and experiments. The system consist of event generator and multiple event receivers which installed local control nodes. The system is ready in the first quarter of 2014. Performance and functionality are investigated systematically. Parameters like delay, skew, latency, drift due to ambient temperature variation, etc. will be addressed. This report wills summary progress of TPS timing system before system delivery for accelerator commissioning.

  The TPS is a latest generation of high brightness synchrotron light source and ready for commissioning. It consists of a 150 MeV electron linac, a booster synchrotron, a 3 GeV storage ring, and experimental beam lines. The booster is designed to ramp electron beams from 150 MeV to 3 GeV in 3 Hz. The TPS control environment is based on EPICS framework to support rich functionalities including power supply control, waveform management, vacuum interface, BPM, intensity monitoring support, operation supports, and so on. This report summarizes the efforts on control environment development for TPS booster synchrotron.

  Control system for the Taiwan Photon Source (TPS) project was implemented. The system is ready for commissioning of the accelerators. Final integration test is in proceeding. The EPICS was chosen as control system framework. The subsystems control interfaces include event based timing system, Ethernet based power supply control, corrector power supply control, PLC-based pulse magnet power supply control and machine protection system, insertion devices motion control system, various diagnostics, and etc. The standard hardware components had been installed and integrated, and the various IOCs (Input Output Controller) are implemented as various subsystems control platforms. Development and test of the high level and low level software systems are in proceeding. The efforts will be summarized at this report.

  Insertion device (ID) is a crucial component in third-generation synchrotron light sources, which can produces highly-brilliant, forward-directed and quasi-monochromatic 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.

  The Taiwan Photon Source (TPS) is being constructed at the campus of the NSRRC (National Synchrotron Radiation Research Center) and commissioning expected in 2014. In order to prevent damage to accelerator components induced by various events, a global machine protection system (MPS) was installed and implemented. The MPS collect interlocks and beam dump requests from various system (thermo/flow of magnets, front-end, vacuum system, and orbit excursion interlock), perform decision, transmit dump beam request to E-Gun or RF system. The PLC based system with embedded EPICS IOC was used as a slow MPS which can delivery less than 8 msec reaction time. The fast MPS was dependent on event based timing system to deliver response time less than 5 μs. Trigger signal for post-mortem will also be distributed by the fast MPS. To ensure alive of the system, several self-diagnostics mechanisms include heartbeat and transient capture were implemented and tested. The MPS architecture, installation, and validation test results were presented in this report.
