Abstract
TL-BA-CA-CU-O THIN FILMS HAVE ZERO RESISTANCE ABOVE 110K AND CRITICAL CURRENTS UP TO 10(6) A/CM(2) AT 77K. IN THICKER SAMPLES THE CRITICAL CURRENT IS LOWER. THUS, TO PREPARE STRONG, "BULK" SUPERCONDUCTORS WE ARE PROPOSING TO MAKE MULTILAYER SAMPLES COMPOSED OF STRONG SUBSTRATES (EITHER HASTALLOY OR CARBON FIBER) ON WHICH A LARGE NUMBER OF LAYERS OF SUPERCONDUCTOR AND BUFFER LAYERS HAVE BEEN DEPOSITED. THESE COMPOSITE STRUCTURES WILL BE CAPABLE OF CARRYING LARGE CURRENTS AND WITHSTANDING LARGE TENSILE STRESSES. THEY WILL BE HERMETICALLY SEALED, TO MAINTAIN LONG-TERM INTEGRITY.
