IPAC'23 - Particle Accelerator Projects and Upgrades

IPAC’23 / PARTICLE ACCELERATOR PROJECTS AND UPGRADES 76 Project Region Asia and Australasia Project Location Hsinchu, Taiwan Project Type Project Update Project Description The Taiwan Photon Source (TPS) began user operations in 2016 and has been operating at its designed beam current of 500 mA since 2021. Currently, it offers users more than 4,600 hours of annual operating time, has a mean time between failures of approximately 130 hours, and achieved an availability rate of about 98.7% in 2022. In preparation for a potential upgrade plan in 10 years, we are allocating resources to advance our accelerator technology with the aim of improving the performance of the light source before the upgrade project begins. Our primary focus is on developing a superconducting third harmonic passive cavity (1.5 GeV), an in-vacuum cryogenic permanent undulator, a nonlinear injection kicker and pulser, and a NEG-coated long-sized vacuum chamber. Furthermore, we are pursuing energy-saving measures, including reducing infrastructure energy consumption in all directions, improving the energy conversion efficiency of our homemade 320 kW, 500 MHz solid-state high-power RF transmitter, and prototyping the replacement of the electromagnetic dipole in our previous light source, the Taiwan Light Source (TLS), with a permanent one. We aim to create a high-flux and bright green light source. The aforementioned technology development items play a critical role in achieving our ultimate goal.
