Abstract
The Bevatron/Bevalac main guide field power supply stores 680 MJ
in the flywheel-shaft systems of two independent motor-generator sets.
During the normal acceleration cycle of various heavy-ion beams, the
energies of the rotating shafts are converted to energy stored in the
main magnet guide field. At the end of the acceleration cycle, the
magnet energy is inverted back to the shafts. Generally, this takes
place from 10 to 15 times per minute. The rapid switching of ions,
energy, and beam lines at the Bevalac has required various control
techniques for fast switching between all operational Bevalac fields
within 1 min. The power supply control systems and operating parameters
are described
