  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.

  The European Spallation Source (ESS) is a collaboration of 17 European countries to build the world's most powerful neutron source for research. ESS has entered the construction phase and the plan is to produce first neutrons by 2019 and to complete the construction by 2025. The Integrated Control System Division (ICS) is responsible to provide control systems for the whole facility. The unprecented beam power of 5 MW and the construction of the facility with many components contributed in-kind presents a number of challenges to the control system. Systems have to be specified so that the work can be effectively shared between the contributors and on-site staff. Control system components need to provide a level of performance that can support the operation of the facility, be standardized so that integration to the facility can be done during a short installation period and be maintainable by the in-house staff after the construction has finished. This paper will outline the plans and principles that will be used to construct the control systems. The selected technologies and standards will be presented, as well as the plans for integration.  
LCLS-II Controls and Safety Systems Status

The LCLS-II FEL at the SLAC National Accelerator Laboratory, a significant addition to LCLS-I, is designed to dramatically decrease data acquisition time by providing high repetition rate over a broad energy range. The design consisting of a CW superconducting Linac with bunch repetition rates of up to one MHz and beam power of several hundred kilowatts requires major enhancements to the LCLS-I controls system. LCLS-II will retain the successful architecture based on EPICS while implementing additional technologies to meet the new requirements. These include a new LLRF system for the superconducting Linac, a new timing system to allow MHz operation, and new data acquisition electronics for the beam position monitors and other beam diagnostic systems. The high beam rate and power also necessitate faster beam abort mechanisms, requiring enhanced machine and personnel protection systems. In order to address the high speed processing and high throughput requirements of a number of systems, an ADC/FPGA/DAC-based system as a common platform for several applications is being developed. This paper presents an overview of the LCLS-II controls and discuss the status of the critical systems.
