Abstract :
The booster synchrotron for the recently commissioned Stanford Synchrotron Radiation Laboratory (SSRL) injector facility employs a 10 Hz resonant magnet power supply system, or White circuit, as described by M.G. White et al. (1956), to accelerate an electron beam from 120 MeV to 3 GeV. Four major design specifications were required to establish the basic White circuit network: (1) the operating frequency; (2) the method of powering the quadrupoles; (3) the number of resonant cells and their configuration; and (4) the DC and AC power supply configuration. The booster dipole and quadrupole magnets are connected in series within a system of 17 distributed resonant cells driven by a pulsing network. Tracking power supplies driving the trim coils of the two quadrupole families are used to stabilize betatron tunes during energy ramping. The White circuit has proven to be a reliable and relatively simple system to operate during its several months of 2.35 GeV operation.<>
