Current Status of the TPS and its Future Prospects

The Taiwan Photon Source (TPS) is a newly commissioned 3-GeV, third-generation, low emittance synchrotron light source located at the NSRRC in Hsinchu, Taiwan. Commissioning and machine conditioning of the TPS occurred between December 12, 2104 and the second quarter of 2016 includes Phases-I accelerator commissioning with warm cavities without insertion devices, installation of two superconducting RF cavities and 10 sets of insertion devices, Phase-II accelerator commissioning and beamlines commissioning. Up to 520 mA of beam current were stored at the storage ring during accelerator commissioning and user service started in September 2016. The machine is equipped with two superconducting RF cavities and seven in-vacuum undulators and three sets of elliptically polarizing undulators to serve phase I beam lines. Routine operation of the TPS delivers to users photons from a 300 mA stored beam current since September 2016 and of 400 mA since last November 2017. To support more insertion devices and operating at 500 mA while improving the reliability of the RF system, a five years project to install the third SRF system was started in early 2018. Insertion devices and front-end installations continue to support Phase -II and -III beam line projects until its expected completion in 2020 and 2023, respectively. Strategic plans to explore the capabilities of the TPS and to remain competitive are addressed. Future accelerator developments are also in continued discussions. This report presents the status of the TPS accelerator system and future prospects.
