Switchable 10 Hz/1 Hz LEB magnet power supply system

摘要

The Low Energy Booster (LEB) is a rapid cycling synchrotron to be built at the Superconducting Super Collider Laboratory in the Injector Complex. The Low Energy Booster will be ready for operation by late 1995. The LEB is used to accelerator protons from an injection momentum of 1.2 GeV/c to an extraction momentum of 12 GeV/c. The machine is a separated function design with dipole and quadrupole magnets driven by a single power supply system. Tracking errors between dipoles and quadrupoles are corrected by separate quadrupole magnets powered from independent power supplies. The dipoles and quadrupoles are excited with a 10 Hz biased sine wave or 1 Hz linear ramp. Change of operating mode from 10 hz to 1 Hz takes no more than 2 hours. This paper describes the present design of the ring magnet power supply system. 5 refs., 5 figs., 3 tabs.
