A Superconducting Magnetic Energy Store on a Torsion-Braced Former

The unit described in this study is a superconducting magnetic energy store intended for bridging power interruptions for sensitive industrial loads. Its operating principle is that a niobium-titanium coil stores energy in its magnetic field and a torsion-braced former carries the Lorentz loads, with the bracing sized against the shear ceiling adopted in this design. The design is computed from stated assumptions throughout; it is simulated, not measured, and no prototype results are reported. The headline result is a stored magnetic energy of 3.24 MJ, obtained with peak field of 5.2 T with a computed efficiency or performance coefficient of 94 per cent where that measure applies, for a unit of mass 420 kg whose characteristic scale is a coil volume of 0.85 m^3. A parameter sweep reported in the Results section shows how the output moves when the principal variable is changed, and the density of the working material, 8.9e+03 kg per cubic metre, sits about 54 orders of magnitude below the neutron-carrier density bound of 9.72e+57 kg per cubic metre, so the bound enters this design as a sizing ceiling and a margin statement rather than as an operating condition. The limitations are stated plainly: cryogenic refrigeration is a continuous parasitic load, and a quench converts the full stored energy to heat inside the cryostat, which the protection system must absorb. Status: SIMULATED, NOT MEASURED.
