UTILIZING SUBCOOLED, SUPERFLUID HELIUM II IN THE DESIGN OF A 12-TESLA TANDEM MIRROR EXPERIMENT.

Author(s) : HOARD R. W., et al.

Summary

A DESIGN STUDY OF 12-T YING-YANG COILS FOR A CONCEPTUAL TANDEM MIRROR NEXT STEP (TMNS) FACILITY HAS BEEN PERFORMED. THE MAGNETS HAVE MAJOR AND MINOR RADII OF 3.7 AND 1.5 M, 0.70 X 3.75 M2 CROSS SECTION, 46.3 MA TURNS, AND AN OVERALL CURRENT DENSITY OF 1,765 A/CM2. EACH COIL IS COMPOSED OF SEVERAL SUBCOILS SEPARATED BY INTERNAL STRENGTHENING SUBSTRUCTURE. THE SIZE OF THE YING-YANG COILS AND THE CURRENT DENSITY WAS REDUCED BY UTILIZING SUBCOOLED, SUPERFLUID HELIUM II AT 1.8 K. THIS PAPER REVIEWS THE STUDY, WITH EMPHASIS ON HELIUM II HEAT TRANSPORT, CONDUCTOR STABILITY AND METHODS ALLOWING THE EXTENSION OF GORTER-MELLINK CHANNEL CALCULATIONS.
