“…In 1980, the mirror program embarked on a tandem mirror, MFTF-B which will store some 3000 MJ of energy, a factor of nearly four larger than the 800 MJ stored by CERN, the largest of the superconducting bubble chamber magnets built in the late 1970's. The birdseye view of the magnet system is given in Figure 1.2 [Henning (1980)].…”

High field solenoid magnets may experience internal damage or eventually collapse due to the powerful magnetic fields they produce. Elastic deformations of the conductor and insulation in these magnets deserve attention because they can cause local damage that can lead to electrical breakdown. In conventional stress analysis of cylindrically wound magnets, the magnetic field gradient, or magnetic stiffness, is usually neglected. However, in this thesis the magnetic stiffness is shown to have a significant effect on the elastic stability and vibration of these magnets. One-turn and multi-turn superconducting rings were used to study the effects of deformations on stability and vibration. Both static and dynamic methods were used to determine the critical buckling currents. The dispersion of natural frequencies with increase in current and subsequent in-plane and out-of-plane buckling of the rings near the critical buckling current were observed. A model based on ring theory and magnetic stiffness was developed to explain experimental observations and showed a fair to good agreement between experimental and theorietical values of the buckling current. This model was used to evaluate the buckling current of 7-and 10-turn magnets. The analysis showed buckling concentrated in the outer turns.

Fusion magnet technology has made spectacular advances in the past decade; to wit, the Mirror Fusion Test Facility and the Large Coil Project. However, further advances are still required for advanced economical fusion reactors. Higher fields to 14 T and radiation-hardened superconductors and insulators will be necessary. Coupled with high rates of nuclear heating and pulsed losses, the next-generation magnets will need still higher current density, better stability and quench protection. Cable-in-conduit conductors coupled with polyimide insulations and better steels seem-to be the appropriate path. Neutron fluenoes up to 10 neutrons/cm in niobium tin are achievable. In the future, other amorphous superconductors could raise these limits further to extend reactor life or decrease the neutron shielding and corresponding reactor size.
