  The 150 MeV linac of Taiwan Photon Source was commissioned in June 2011. It consists of 90 keV electron source, bunching system and three S-band accelerating sections driven by three high-power klystrons. The rf system is equipped with rescue option such that the rf power from second klystron can be split and fed into both accelerating section 1 and 2. The rescue operation will be needed in the event of a failure occurred at the first klystron. In the report, the rescue capability will be illustrated and the test results will also be discussed.

  Taiwan Photon Source (TPS) is a 3 GeV third generation light source and will be operated in top-up injection mode. The leakage field of the septum magnet will dominate the injection performance. The septum magnets, parts of injection system, consist of AC and DC current mode magnets. The AC septum magnet were designed and constructed by NSRRC. In order to verify the magnetic field quality and the leakage field distribution, the search coil probe and the printed circuit technology for long coil probe measurement systems are developed and implemented for magnetic field measurement. This paper will describe the magnetic field measurement system, the magnetic field mapping results and the field shielding performance of AC septum magnet.

  A set of kicker power suppliers has been designed and fabricated for storage ring beam injection of the Taiwan Photon Source (TPS) project. In order to fulfill the requirements, the performance of the designed units has been bench tested and the results are examined. The matching in four pulsers, the pulse-to-pulse stability and the time jitter are specified according to the beam injection requirements. The engineering evaluation and the measurement results are briefly discussed.
