Abstract :
The PLS has provided 2.5 GeV electron beam to users of beam lines since Jan. 2000. During Jan. 2000 to Oct. 2002, 2 GeV electron beam was injected from the linac to the storage ring and the storage ring had used energy ramping process to increase the beam energy to 2.5 GeV. Instead of energy ramping process, we have used the 2.5 GeV full energy injection from the linac to the storage ring since Oct. 2002. We present the activities on the stability and reliability of the linac for 2.5 GeV operation, stabilities of injection kicker and septum magnets in the storage ring, orbit correction of COD due to leakage field of the septum magnet, and a DC bump for beam injection. Orbit stabilities and global orbit correction on the operation of 2.5 GeV full energy injection are also presented
