Abstract
A superconductive apparatus having therein at least a superconductive member includes a lithium containing member so as to interrupt neutrons directed to the superconductive member.
Claims9
A superconductive apparatus comprising;
- a superconductive member;
- and
- a lithium member of a lithium metal alloy selected from a group consisting of a lithium aluminum alloy and a lithium containing stainless steel, disposed so as to protect a portion of said superconductive member from undesired radiation impingement thereon, said lithium member having equivalent lithium thickness of at least 3 mm.
A superconductive apparatus comprising:
- a superconductive application element;
- at least a superconductive member constituting at least a portion of said superconductive application element;
- a heat insulating material surrounding the whole of the superconductive application element;
- a lithium member of a lithium metal alloy selected from a group consisting of lithium aluminum alloy and lithium containing stainless steel, said lithium member having equivalent lithium thickness of at least 3 mm and disposed outside said heat insulating material so as to protect said superconductive application element from undesired radiation impingement thereon.
1 more element
A superconductive coil apparatus comprising:
- a plurality of superconductive coils;
- a member of a lithium, metal alloy selected from a group consisting of a lithium aluminum alloy and lithium containing stainless steel, said member having equivalent lithium thickness of at least 3 mm and dispose so as to cover said portion of said plurality of superconductive coils to protect said coils from undesired radiation impingement thereon.
