摘要： A magnetic field generator has a superconductive coil (1) immersed in a coolant material (6). When power is supplied to the superconductive coil (1) from a suitable power source (5), the superconductive coil (1) is energised to generate the magnetic field. The ends of the superconductive coil (1) may then be shorted through a persistent current switch (2), to maintain the magnetic field without the need for further power. The persistent current switch (2) has a superconductive connection (12) connected across the ends of the superconductive coil (1) and a heater (13). These components are enclosed in a casing (15) with a gap (14) between these components and the casing (15). Apertures (16) in the casing (15) permit coolant material (6) to enter the gap (14). When the heater (13) is energised, it heats the coolant material (6) in the gap (14) until it vaporises. There is then a significant decrease in the thermal conductivity through the gap (14) hence the superconductive connection (12) is heated rapidly to its critical temperature. Only low power is needed. When the heater (13) stops being energised, liquid coolant material (6) fills the gap (14) thereby rapidly cooling the superconductive connection (12) to below its critical temperature.

摘要： 57 Electrical switches used in conjunction with high energy superconductive windings must be able to quickly absorb large amounts of electrical energy since switching of the superconducting current is accomplished by means of transition to the resistive state in the switch portion of the superconducting current loop. Furthermore, to minimize the heat generated during the transition to the resistive state, the switch itself should exhibit a relatively high resistance while at the same time exhibiting a low external magnetic field. The switch should also exhibit minimal stray magnetic fields, expecially in those applications requiring field uniformity. These objectives are achieved in a persistent current switch , (10) which includes a length of superconductive material disposed in a compact, thermally insulated volume (40) which also includes a mechanism for heating (30) at least a portion of the superconductive conductor in the switch in order to return it to its resistive state. Furthermore, there is included a mass of thermally conductive material within the volume which is in thermal contact with at least a substantial ( portion of the superconductive conductor to mitigate the effects of hot spots occuring within the switch.
