A NOVEL METHOD FOR MANUFACTURE OF HIGH TEMPERATURE SUPERCONDUCTING COILS FOR HIGH TEMPERATURE OPERATION

THE PRIMARY OBJECTIVE OF THIS PROJECT IS THE DEVELOPMENT OF HIGH TEMPERATURE SUPERCONDUCTING (HTS) COIL TECHNOLOGY SUTIABLE TO PRODUCE AT LEAST ONE TESLA (T) AT PUMPED LIQUID NITROGEN TEMPERATURES. THE PHASE I PROJECT WILL CONTINUE TO DEVELOP A NEW APPROACH FOR INCREASING THE PERFORMANCE OF HTS COILS FOR HIGH TEMPERATURE OPERATION. THE TECHNICAL APPROACH BEING FOLLOWED IN THIS WORK WILL ALLOW ACHIEVEMENT OF CITICAL CURRENT DENSITIES (JC) EQUIVALENT TO THE BEST RESULTS OBTAINABLE BY SHORT SAMPLE PRESSING. THE ACHIEVEMENT OF JC VALUES ON THE ORDER OF 30,000 TO 60,000 A/CM(2) IN THE FINAL COIL CONFIGURATION WOULD THEN ALLOW, FOR THE FIRST TIME, SERIOUS CONSIDERATION OF DEVICES TO BE OPERATED AT CRYOGENIC TEMPERATURES SUCH AS PUMPED LIQUID NITROGEN (64 K) WITH MAGNETIC FIELD GENEATION OF AT LEAST ONE TESLA.
