  Top-up operation has been started since many years ago at Taiwan Light Source Storage Ring (SR). For this operation it is important to reduce the beam injections should not excite the oscillation of stored beams. For further reduction of these oscillations, corrections with kicker-magnets are used. The details of the study will be reported in this paper.

  In this paper, the booster injection efficiency and the parameter working range related to key components in-cluding septum magnet and kicker magnet for Taiwan Light Source (TLS) injector operation are introduced. Booster injection scheme for different lattice is explored by machine study plan using injector property. The study result may be used by the operator as booster injection parameter fine tuning reference. It is also helpful for the advanced injection scheme exploration.

  Machine operation parameters and interruptions to user beam at Taiwan Light Source (TLS) and Taiwan Photon Source (TPS) are recorded in databases. The data retrieve to TLS uses the File Transfer Protocol (FTP) with two separated databases 10 Hz and 0.1 Hz for quick or detail data analysis options. TPS data storage uses the open source database PostgreSQL. A statistical analysis package HISTORY has been writ-ten in Microsoft Visual C to perform operation monitor-ing and data mining. Operation and failure statistics func-tions are produced for performance evaluation and User Administration & Promotion Office user time statistics.

  With the beam energy of 1.5 GeV, the storage ring of Taiwan Light Source (TLS) in National Synchrotron Radiation Research Center (NSRRC) has provided research service to users for more than twenty years. It takes a lot of efforts to keep this accelerator reliable and to improve its stability. NSRRC has finished the construction and commissioning of the new 3-GeV accelerator Taiwan Photon Source (TPS) which will be opened to users with limited beam lines in 2016. On the other hand, TLS has 25 beamlines and still serves users very well as being benefited by its mature operation skills and continuous efforts on maintenance and system improvement. Main challenges and corresponding solutions on TLS operation in these recent years t are presented herein, together with the statistics on operation performance.
