Abstract

The author describes the present design of the ring magnet power supply system of the low-energy booster (LEB), a rapid cycling synchrotron to be built at the Superconducting Super Collider Laboratory in the injector complex. The LEB 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 h. The magnets, the 1 Hz and 10 Hz modes of operation, and the harmonic and power factor correction are discussed.<>
