  The preinjector of the Taiwan Light Source(TLS) is consist of a 140 kV themionic gun and a 50 MeV traveling wave type linear accelerator system. In order to improve performance, to decouple the vacuum interlock logic from the linac control system, and to provide a better control functionality for top-up operation and to avoid obsolescence, linac control system have been renew. One VME crate system is dedicated for linac control, new hardware equips with high resolution of analog interface to provide better control. Vacuum interlock logic will be done be a dedicated programmable logic controller(PLC). The remained linac devices have sequential control needed will be done by another PLC, such as door access interlock, klystron warm up, gun warm up, trig interlock, gun high voltage interlock, klystron modulator high voltage interlock, water flow interlock. Both interlock and sequence control PLC will control by the VME crate. All the other functions without interlock or sequence requirement will control by the VME crate directly. New control system expects to provide better control functionality, better performance, easy for maintenance, and useful easy to add new hardware equipments.

  Routine top-up operation of Taiwan Light Source (TLS) was started from October 2005 after high efficiency multi-bunch instabilities suppression system put into service. To support the top-up operation, various diagnostics and timing supports are needed. These include diagnostics for injection efficiency, filling pattern of the storage ring, tune, instability, loss pattern measurement. Timing control of the injection process are also needed. Design consideration and details of these efforts will be summary in this report. Further possible improvement will be also discussed.

  Performance of an electron linear accelerator is very important for synchrotron light source application. Its performance will decide the reproducibility of filling pattern in the booster synchrotron. The filling pattern of the booster synchrotron will affect filling pattern control of the storage ring. The RF feed-forward control can improve performance of linear accelerator deistically. Design consideration and details of the implementation will be summary in this report.

  The beam trip event diagnostic system includes several eight channels high-speed digitizer for data acquisition, PC base computer and optical fibre network applies to capture data. The PC are also to serve signal processing, beam trip event analysis and archive. This system can integrate beam trip, interlock signal of SRF, waveform of the injection kicker, quench and interlock signal of the superconducting insertion device, and instability of the stored beam. This diagnostic system can be routine monitor signal and record beam trip event. Design consideration and details of the implementation will be summarized in this report.

  Digital camera has been adopted for the booster, storage ring and transport-line diagnostic recently at the Taiwan Light Source. The system provides low image distortion and lossless image transmission over long distances. The system is integrated with commercial software in the control system. The fully remote control supports various operations and application that is useful. These applications include of screen monitor equip in the booster and storage ring, wider dynamic range sensor and highly flexibility control for the emittance measurement in the transport line, booster and linac. System configuration and present status will be summarized in this report.
