THE TAIWAN LIGHT SOURCE AND SUPERCONDUCTING CAVITY

The Taiwan Light Source (TLS) is a third-generation light source with low-emittance and low operating energy, 1.5 GeV, which is used as ultra-violet and soft xray light source in Taiwan. Doubling the photon flux and stored beam current has been proposed to users by upgrading the RF system to superconducting cavity. The cavity’s upgrading project is expected to reduce the longitudinal coupled bunch instability and increase beam lifetime by doubling the operation gap voltage. Machine status, beam parameters, RF characteristics, cryogenics system, safety issues on operation and simulation of high-power components will be presented.
