  Direct Current Current Transformer (DCCT) is the most commonly used high precision current monitor in modern particle accelerators including Shanghai Synchrotron Radiation Facility (SSRF). Three types of noise have been observed in the output signal of the DCCT in the storage ring of SSRF: power line noise, beam current related narrow band noise and random square wave noise from nowhere. This article will discuss the noise removal algorithms in SSRF and the performance of the DCCTs afterwards.

  TPS (Taiwan Photo Source) is a third generation 3 GeV synchrotron light facility, featuring ultra-high photon brightness with extremely low emittance which will be a state-of-the-art synchrotron radiation facility and is being in construction at National Synchrotron Radiation Research Center (NSRRC) campus. Beam image profile and its analysis play an important role in beam diagnostics of a particle accelerator system. However, due to the CCD image collection devices are distributed around the linac, booster, and storage ring, a distributed EPICS system based image profile diagnostics solution was proposed, which are based on GigE Vision camera with PoE support. This solution provides an easy way for cabling, and delivery adequate performance. Implementation plan for the TPS and results of prototype test at existed facility to examine functionality of hardware and software will be summarized in this report.

  Studies are going on of a new wire scanner concept. All moving parts are inside the beam vacuum and it is specified for use in all the machines across the CERN accelerator complex. Key components have been developed and tested. Work is now focussing on the installation of a prototype for test in the Super Proton Synchrotron (SPS) accelerator. This article presents the specification of the device and constraints on the design for integration in the different accelerators at CERN. The design issues of the mechanical components are discussed and optimisation work shown. Finally, the prototype design, integrating the several components into the vacuum tank is presented.

  Taiwan Photon Source (TPS) is a 3 GeV synchrotron light source which is being construction at campus of NSRRC. Various diagnostics are in implementation and will deploy in the future to satisfy stringent requirements of TPS for commissioning, top-up injection, and operation. These designs include beam intensity observation, trajectory and beam positions measurement, destructive profile measurement, synchrotron radiation monitors, beam loss monitors, orbit and bunch-by-bunch feedbacks, filling pattern and etc. are in final design phase. Progress of construction of the planned beam instrumentation system for the TPS will be summarized in this report.

  The new BPM electronics Libera Brilliance Plus are developed for Taiwan Photon Source (TPS) which is a 3 GeV synchrotron light source constructed at NSRRC. This new BPM electronics can accommodate four BPM modules with integrated FPGA-based hardware. The preliminary test for the first arrival unit had been performed in the TLS (Taiwan Light Source) and had shown nearly equal performance compared with Libera Brilliance. The extra 75 sets had been delivered in 2011 and 2012. Performance of each unit are individually tested and measured.

  This report describes the electron beam longitudinal studies performed at ALBA Storage Ring using the streak camera. We first show the usual studies involving precise bunch length measurements and related beam parameters like energy spread or momentum compaction factor. Next, the studies to match the injected beam in energy and phase are reported and compared with simulations.

  A new synchrotron radiation facility, Central Japan Synchrotron Radiation Research Facility is built in Aichi area. The light source accelerator complex consists of a 1.2 GeV compact electron storage ring and a full energy injector for top-up operation. The key equipments of the accelerator are four 5 T superconductive bending magnets. Although the acceleration energy of the storage ring is relatively low, synchrotron radiation from the superconductive bending magnet reaches hard X-ray region and can be provided for more than 10 beamlines. Construction of the facility started in 2010 and finished in Apr. 2012. Commissioning of the accelerator complex started in Mar. 2012. We adapted a turn-by-turn beam position monitoring system based on a digital oscilloscope developed at the UVSOR. In the presentation, we report on details of beam diagnostics conducted during the commissioning.
