The upgrade of SRRC booster extraction system

It is planned to upgrade the SRRC booster from 1.3 GeV to 1.5 GeV for full energy injection into the storage ring before the end of 1999. Based on the technical specification and operation experience, it is concluded that some of the subsystem components need to be rebuilt, such as the magnet power supply systems and beam extraction elements. A review of the power supply system will be reported elsewhere. In this report, the brief review of the beam extraction process is given according to the 1.5 GeV parameters. The test result of a modified kicker magnet is presented.
