  Taiwan Photon Source (TPS) is a third-generation 3-GeV synchrotron light facility, located in National Synchrotron Radiation Research Center (NSRRC) at Hsinchu Science Park. After overcoming many challenges, the storage beam current attained 520 mA in 2015 December. The synchrotron light monitors, including X-ray and visible light, are important diagnostic tools to characterize the various machine conditions. The booster beam dynamics during ramping and the beam properties of the storage ring were studied with synchrotron light. The results of measurements are presented in this report.

  Taiwan photon source (TPS) is a 3rd generation and 3 GeV synchrotron light source in NSRRC. Several types of beam loss monitors (BLMs) such as RadFETs and PIN-diode BLMs are installed in the storage ring to understand the beam loss distribution and mechanism during the injection, decay mode, top-up operation and beam trip. Several RadFETs are also installed around the inserting devices to study the beam loss near the linear scalar. The preliminary beam loss study using RadFETs are PIN-diode BLMs in the storage will be summarized in this report.

  The Taiwan Photon Source (TPS) is a low-emittance 3-GeV light source at Natioal Synchrotron Radiation Research Center, next to the Taiwan Light source (1.5 GeV). On March 26, 2015, the TPS storage ring with two 5-cell PETRA cavities has successfully operated in 100 mA in top-up mode without the installation of insertion devices (IDs). To reach the design goal of 500 mA, the machine was shut down for 5 months to replace PETRA cavitites with superconducting RF (SRF) cavities and to install 10 IDs: 7 in-vacuum undulators (IU) and 3 elliptically polarized undulators (EPU). The commissioning of TPS storage ring with SRF cavities and IDs began in Sep. 2015. In this paper, we present our results and proceedures of ID commissioning.

  The traditional alarm systems usually set up/low limit for various signals. When the acquired values exceed the limits, the alarm system would be activated. The proposed system in this article can focus on various possible events with many kinds of signals for response judgments. During alarm calling period, data can also be announced and recorded. The system can also monitor various events according to different time shifts. Integrating LabVIEW, mobile phone, AT-command and Bluetooth communication, the system can handle factory broadcast, sending E-mail and SMS message. The above sound and words messages can be set directly at the home-made software interface. The new intelligent alarm system can eliminate the procedure made by man with the added event recording, system stability improvement and debugging function in wider application fields.

  Low-cost credit-card size SBCs (single-board computer) are with small footprint, powerful in CPU performance and rich interfaces solution to widely adopted for educational purposes and also suitable for small scale embedded applications. The card-size SBCs have been applied for several applications with EPICS support at the TPS control system environment as auxiliary supports which are not suitable to use standard platform in existed control system due to economics, simplicity, specialty view points. The more efforts of several implemented applications are summarized in this paper.

  Taiwan Photon Source (TPS) with low emittance provides extremely bright X-rays. Seven advanced phase-I beamlines of TPS are being constructed and commissioned. The control interfaces for a beamline or experimental station and support from the accelerator control system are designed and are being implemented. The beamline control interface and supports include a beamline interlock status monitor, accelerator timing transmission, broadcast of accelerator operating status, transmission of the beam-current reading and control of insertion devices. This report summarizes the efforts in implementing the beamline EPICS IOC and support from the accelerator control system during beamline commissioning in TPS phase-I.
