System and method for magnetization of rare-earth permanent magnets

A system for cooling a superconducting material used for magnetization of magnets disposed within a cylindrical structure, the system comprising:

• a first tubing system for allowing a cooling gas to interact with a high-field strength superconducting material to thermosiphon-cool the high-field strength superconducting material;
• a second tubing system for allowing a cooling gas to interact with a low-field strength superconducting material to thermosiphon-cool the low-field strength superconducting material;
• and
• a cooling gas in liquefied form configured to flow through the first tubing system and/or the second tubing system;
• wherein an outlet of the first tubing system and an outlet of the second tubing system are located at a same location on a surface of the cylindrical structure.

A system for cooling a superconducting material used for magnetization of a permanent magnet disposed within a cylindrical structure, the system comprising:

• a wicking panel film configured to interact with a superconducting material configured to magnetize the permanent magnet;
• a cooling liquid configured to interact with the wicking panel film;
• and
• a cryocooler in communication with the wicking panel film through which the cooling liquid traverses;
• wherein the cryocooler is located at a same location on a surface of the cylindrical structure when a plurality of cryocoolers is provided;
• and
• wherein the cooling liquid is gravitationally fed through the wicking panel film to provide for reuse of the cooling liquid by the cryocooler.

A method for cooling a superconducting material used for magnetization of a permanent magnet disposed within a cylindrical structure, the method comprising:

• providing a first tubing system for allowing a cooling gas to interact with a high-field strength superconducting material to thermosiphon-cool the high-field strength superconducting material;
• providing a second tubing system for allowing a cooling gas to interact with a low-field strength superconducting material to thermosiphon-cool the low-field strength superconducting material;
• locating an outlet of the first tubing system and the second tubing system at a same location on a surface of the cylindrical structure;
• feeding a cooling gas in liquefied form through the first tubing system and/or the second tubing system to cool the at least the high-field strength superconducting material and/or the low-field strength superconducting material;
• and
• returning the cooling gas to a location to be fed again through the first tubing system and/or the second tubing system.
