An 80 kG-Foot Beam Switching Magnet and Its Pulsed Current Supply

A flattopped switching magnet system has been developed for deflecting the beam of the Zero Gradient Synchrotron (ZGS) to a bubble chamber. A 13 kV, 100 kJ capacitor bank provides the pulse energy. The flattop is maintained within ± 0.005% by a low voltage capacitor bank. The discharge circuit oscillates for little more than one-half cycle and 96% of the pulse energy is returned to the capacitor bank.
