Abstract

Routine top-up operation of Taiwan light source (TLS) was to commence from October 2005 after high efficiency multi-bunch instabilities suppression system put into service. Long-term 360 mA top-up operation has been tested and proven its successful and steady performance. Short-term 400 mA top-up run is also demonstrated. The TLS is current operated at 300 mA top-up mode to compromise various requirements of users at this moment. Higher current is possible in future. To support the top-up operation, various diagnostics and timing control 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 is also necessary. Further possible improvement will be also discussed.
