FABRICATION AND TESTING OF A SUPERCONDUCTING COIL: PHASE 3 OF THE MAGLEV DEVELOPMENT PROGRAM

Report documents research on superconducting magnet technology suitable for the levitation and propulsion units of the Canadian Maglev vehicle. This research involved the design, fabrication and testing of a recatrack coil using epoxy-impregnated windings of copper stabilized NbTi wire. The following results were achieved: Fabrication and testing of a magnet with a strength of 400,000 Amp-turns in a support frame; selection and characterization of cryogenic strain gauges; characterization of strain in solenoidal and racetrack superconducting magnets; design, fabrication and testing of high current persistent switches and operation of superconducting magnets in persistent mode.
