Abstract
A persistent current switch in a superconducting magnet, includes: a winding part in which a superconducting wire is noninductively wound; a winding-heating heater provided around the winding part; a vessel provided around the winding part with a space; and an anti-convective material provided in the space between the vessel and the winding part.
Claims7
A superconducting magnet comprising:
- a persistent current switch for operating in a persistent current mode,
- wherein the persistent current switch comprises:
- a winding part in which a superconducting wire is noninductively wound;
- a winding-heating heater for heating the winding part to a critical temperature thereof or higher by thermally being in contact with the winding part;
- a vessel provided around the winding part and the winding-heating heater with a space between the vessel and both the winding part and the winding-heating heater;
- and
- an anti-convective material provided in the space between the vessel and both the winding part and the winding-heating heater.
