  The TPS is a state-of-the-art synchrotron radiation facility featuring ultra-high photon brightness with extremely low emittance. Its Booster has 6 FODO cells which include 7 BD dipoles with 1.6 m long and 2 BH dipoles with 0.8 m long in each cell. After magnetization of stainless steel vacuum chamber of the booster were identified and then dismantled, annealed, and re-installed, the electron beam energy of the Taiwan Photon Source (TPS) in the booster ring has ramped to 3 GeV in a week. The booster tune correction during ramping is one of the main reasons why the booster commissioning progress is so fast. In this paper the summarized the booster tune monitor system will be summarised

  For a low emittance light source, beam orbit motion needs to be controlled within submicron for obtaining a high quality light. Magnets vibration especially quadruples will be one of the main sources to destroy the beam stability. In order to study the relationship between vibration and beam motion, it is highly desirable to use a synchronous data acquisition system which integrates measurement of vibration and beam position monitor systems especially for the coherence analysis. For a larger vibration such as earthquakes are also deleterious to beam stability or even make the beam trip due to the quench of superconducting RF cavity. A data acquisition system integrated with an earthquake detector is also quite necessary to show and archive the data on the control system. The data acquisition systems of vibration and earthquake measurement system are summarized in this report. The relationship between the beam motion and magnets vibration will also study here.

  Con¬trol sys¬tem for the Tai¬wan Pho¬ton Source (TPS) has been completed in 2014. Com¬missioning of the accelerator system is in proceeding. Electron beam were stored at the stor¬age ring and emit first light in De¬cem¬ber 31, 2014. TPS con¬trol sys¬tem adopts EPICS toolk¬its as its frame¬works. The sub¬sys¬tems con¬trol in¬ter¬faces in¬clude event based tim¬ing sys¬tem, Eth¬er¬net based power sup¬ply con¬trol, cor¬rec¬tor power sup¬ply con¬trol, PLC-based pulse mag¬net power sup¬ply con¬trol and ma¬chine pro¬tec¬tion system, in¬ser¬tion de¬vices mo¬tion con¬trol sys¬tem, var¬i¬ous di¬ag¬nos¬tics re¬lated con¬trol en¬vi¬ron¬ment, and etc. The stan¬dard hard¬ware com¬po¬nents had been in¬stalled and inte¬grated, and the var¬i¬ous IOCs (Input Out¬put Con¬troller) had been im¬ple¬mented as var¬i¬ous sub¬sys¬tems con¬trol platforms. Low level and high level hard¬ware and software are tested in¬ten¬sively in 2014 and final re¬vise to pre¬pare for rou¬tine op¬er¬a¬tion is under way. Ef¬forts will be sum¬ma¬rized at this paper.
