Abstract :
The Taiwan Light Source (TLS) is a synchrotron radiation facility that has operated for the past four years at SRRC. At this time, the operating energy has been increased from 1.3 GeV to 1.5 GeV, and the beam lifetime is 9 hours at a current of 200 mA. The monthly uptime is normally more than 90%, and the orbit stability better than 5 micrometers. Both transverse and longitudinal instabilities have been observed, and the corresponding feedback systems have been constructed. The transverse feedback system is in routine operation. A fast orbit feedback system is capable of restricting orbit errors to within 10 micrometers, even in the presence of strong orbit perturbations such as insertion-device gap changes
