HIGH FIELD SUPERCONDUCTING MAGNET USE

DEVELOPMENT OF A BASIC MANUFACTURING PROCESS TO FABRICATE V-ZR-HF LAVES PHASE (C15) SUPERCONDUCTOR IS EXAMINED WITH SCALE-UP TO COMMERCIAL QUANTITIES. SUPERCONDUCTORS BASED UPON A V-ZR-HF SYSTEM OFFER EQUAL TO SUPERIOR PROPERTIES TO TO THE NB3SN CONDUCTORS CURRENTLY USED IN HIGH FIELD SUPER- CONDUCTING MAGNET APPLICATIONS, PARTICULARLY NMR SPECTROMETERS. THE SUPERIOR PROPERTIES OF THE LAVES PHASE V-ZR-HF SUPERCONDUCTORS INCLUDE CRITICAL FIELDS IN EXCESS 20 TESLA, INCREASED MATERIAL DUCTILITY, CRITICAL CURRENT DENSITITES COMPARABLE TO THOSE SEEN IN NO ELASTIC STRAIN DEGREDATION OF CRITICAL CURRENT AND AN INCREASED RESISTENCE TO RADIATION DAMAGE OVER CONVENTIONAL A15 (I.E. NB3SN) TYPE SUPERVCONDUCTORS. COMPARED TO CURRENTLY AVAILABLE A15 SUPERCONDUCTORS WHICH EXHIBIT AN INHERENT BRITTLENESS AND STRAIN SENSITIVITY, THESE C15 LAVES PHASE SUPERCONDUCTORS DO NOT EXHIBIT SUCH PROPERTIES; THEREFORE OFFERING THE MAGNET DESIGNER MUCH MORE FREEDOM TO OPTIMIZE HIS DESIGNS. THE PROGRAM OBJECTIVES ARE: 1) THE DEVELOPMENTOF A BASIC MANUFACTURING TECHNOLOGY FOR V-ZR-HF CONDUCTORS 2) THE PREPARATION OF SAMPLES UTILIZING METHODS DEVELOPED IN 1, AND 3) THE CHARACTERIZATION OF THE PREPARED SAMPLES.
