Abstract

The effect of thermal cycling between 4.3 K and 298 K within a He atmosphere, and ambient magnetic field, on the J/sub c/ of a Bi-2223/Ag-sheathed monocore tape and two Bi-2212/Ag-sheathed multifilament wire straight samples was studied. The J/sub c/ of the tape and wire samples did not degrade as a result of thermal cycling. There was also no degradation of J/sub c/ of these samples by thermal cycling between 77.4 K and 298 K by immersion in LN/sub 2/ within air.<>
