Modular magnet current regulator (for CEBAF accelerator)

A straightforward and versatile power supply system has been designed to drive the lower power corrector and focusing magnets in the (CEBAF) (Continuous Electron Beam Accelerator Facility) accelerator beam transport system. A simple bipolar regulator module furnishes 200 W, with loads to 800 W handled by paralleling up to four modules. Current ripple is 100 p.p.m. of full scale, with stability of 100 p.p.m. over 8 h. Common bulk power supplies furnish power for the regulators. Monitoring and control of the regulator channels is provided by CAMAC power supply controller modules. One status bit and one control bit are provided for each regulator. The current regulators are linear, bipolar modules capable of parallel connection for higher current output. >
