A niobium-titanium solenoid has been operated under isochoric, ie sealed constant volume conditions. Pressures were allowed to rise to over 400 kPa and the operation was continued beyond the critical J-H-T surface of the superconductor, which was found to be in good agreement with published data. Demountable current leads of a modified Efferson type, and a mechanical semi-persistent switch, were used with the coil. The results support the design proposals for isochoric operation of the superconducting magnets of the Canadian Maglev system, but the test system required a more sophisticated thermodynamic analysis to account for the large neck effects in the test dewar.
