  Accelerator applications need extremely precise and highly digitized power supplies for various magnets. A new digital controller for accelerator power supply was developed and implemented. It is a high-performance and multifunctional digital controller which with dual-processor system and Ethernet interface. Due to the digital controller's high resolution Analog to Digital Converter, high resolution Pulse-Width Modulation generator and precise timing design, it can precisely control the accelerator power supply output static or dynamic output. In addition, it also performed well on multi-controller's synchronous control.

  We have upgraded the accelerator control network system for SuperKEKB, the upgrade of the KEKB asymmetric energy e+e collider for the next generation B-factory experiment in Japan. For SuperKEKB, the accelerator control network system with the higher performance of the wider bandwidth data transfer, and more reliable and redundant configuration, is required, to ensure the robust operations under the 40 times higher luminosity. We install the 10 gigabit Ethernet (10GbE) network switches for the wider network bandwidth and optical cables to construct the redundant network. We reconfigure the network design to connect the accelerator control network and the KEK laboratory network to enhance the security. For the beamline construction and the accelerator components maintenance, we install the new wireless network system consists with the Leaky Coaxial (LCX) cable antennas and collinear antennas, which have good radiation hardness of >1MGy, into the 3 km circumference accelerator tunnel. In this paper, we describe the design and current status of the SuperKEKB accelerator control network system.

  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.

  The 3 GeV Taiwan Photon Source (TPS) synchrotron light source is ready for commissioning. Various waveforms includes booster power supply current, pulse magnets current, beam signal, and etc. need monitoring to support commission and routine operation. Remote access of waveforms and spectrums from various digitizer, oscilloscope and spectrum analyzer were implemented to eliminate requirements of long distance cabling and to improve signal quality. Various EPICS supports of Ethernet-based oscilloscope and spectrum analyzer for the TPS are developed for filling pattern measurement, beam spectrum, pulse magnet power supply, and etc. Different operation interfaces to integrate waveform and spectrum acquisition are implemented by various GUI tools to satisfy all kinds of applications. The efforts will be summarized at this report.
