Abstract :
The booster of SRRC is a 1.3 GeV synchrotron with 10 Hz repetition rate. Electron beam from 50 MeV accelerates to 1.3 GeV within 50 msec. It serves as the injector for 1.3~1.5 GeV storage ring of Taiwan Light Source (TLS). To reduce heat related problem in the machine and beamline optics, 1.5 GeV full energy injection is scheduled in near future. The closed orbit measurement system of booster synchrotron consists of 23 sets of BPMs, multiplexes, 500 MHz receivers, timing control electronics and VME bus transient digitizer. The closed orbit is sampled every 150 μ sec, 600 orbits acquired while the energy ramping. The closed-orbit is observed as function of energy. The orbit change due to imperfection of lattice and slow pulse magnet is easily observed. This system is expected to provide us abundant information to improve the operation efficiency and booster troubleshooting
