Patent ID: 8812069

Claim:
A low loss joint ( 10 ) for superconducting wire ( 330 ), comprising; a joining block ( 100 ) integral to and in electrical connectivity with a completed joint ( 10 ) having a body ( 110 ) with an external body surface ( 112 ) and an internal body surface ( 114 ), a variable volume block cavity ( 120 ) in releasable fluid communication with an ambient atmosphere through at least a first block opening ( 130 ), a variable volume block cavity volume ( 122 ), at least a first variable position closure ( 140 ), and at least one superconducting wire termination assembly port ( 170 ); at least one superconducting wire ( 330 ) enclosed at least in part with superconducting wire stabilizer ( 340 ); at least one superconducting wire termination assembly ( 300 ) enclosing the at least one superconducting wire ( 330 ) extending into the variable volume block cavity ( 120 ) from the external body surface ( 112 ) to the internal body surface ( 114 ), and wherein, the variable volume block cavity ( 120 ) further comprises at least one superconducting joining material ( 600 ) substantially filling the variable volume block cavity ( 120 ) and in electrical communication with the at least one superconducting wire ( 330 ).
