STATUS OF THE SPring-8 LINAC

The SPring-8 linac has been improved in order to stably maintain top-up injections into a booster synchrotron and the NewSUBARU storage ring: RF phase variations in a long drive line has been finally stabilized. Beam feedback controls compensate for residual long-term variations of beam trajectory and energy. Enhancement of machine reliability has reduced the down time of the top-up injection to 0.2%. An RF gun test bench has been reinforced: A laser shaping optics successfully generated an almost ideal laser shape to realize low emittance electron beams.
