SUPERCONDUCTING MAGNET SYSTEM FOR HIGH-POWER MICROWAVE SOURCE FOCUS AND ELECTRON CYCLOTRON DEVICE

摘要

A superconducting magnet system for a high-power microwave source focus and electron cyclotron device includes a chiller (11), a vacuum chamber (12), a supporting rod (13), a heat radiation shield (16), a low-temperature system and a superconducting magnet (15). The superconducting magnet (15) includes an inner superconducting main coil (1), an outer superconducting main coil (2), two end compensating coils (3), a regulating coil (4) and a central regulating coil (5). Said coils are wound by Nb3Sn/Cu superconducting wire. The solid nitrogen formed by the chiller (11) and high-pressure nitrogen enables the superconducting magnet (15) to operate off line. The closed loop formed by the superconducting magnet (15) and a superconducting switch (18) makes a magnet field stable and not disturbed by outer electromagnetism. The superconducting magnet system can provide high-stable magnet field with special space distribution.
