“…In recent years, pulsed magnets for fields up to 70 T with long pulse duration have been developed [1][2][3], and the design of magnets for the 70-100 T range is in progress [4]. All these magnets work with a pulse duration of the order 10 ms (half-period of a damped sine wave).…”

The coupled partial differential equations for magnetic and thermal diffusion are solved numerically on a personal computer. The evolution of the field and temperature profiles in each layer of the coil is calculated, taking into account the skin effect, magnetoresistance and heat conduction. This is then used to calculate the pulse shape of the capacitor discharge which energizes the coil. The calculated results are in good agreement with test results for a large range of different coils; this provides useful insight for optimized coil design.

“…Using the most advanced materials and sophist,icated coil design, peak fields up to about 75 T have been achieved in half inch bores, and fields up t o BO T are available for daily experimentation. These recent developmenk in materials science and coil design have given rise to optimism t,hat fields up to 100 T may eventually be achieved nondestructively, and corresponding research projects are under way [3].…”

“…mechanical strength of the coil, leading t o coil explosion. Presently, substantial efforts are made to develop mechanically strong conductors and coils with internal and ext8er-nal reinforcement [3]. With a lot of optimism, it is anticipated that fields up t o 100 T can be generated without coil destruction.…”

Recent developments in the design of pulsed laboratory magnets are reviewed. There are two general categories with many variations: nondestructive magnets for fields below 100 T with pulse durations from 0.1 ms t o 1 second, and destructive magnets with pulse durations from 0.1 t o 10 ps. Nondestructive magnets are mostly wire-wound coils with internal and external reinforcement. The peak field depends on the strength of the materials (strong wires, fibre composites) and on the geometry (bore size, distribution of reinforcement and current density) which can be optimized. Megagauss magnets rely on inertial confinement; this is the reason for the short pulse duration. The field is either generated by magnetic flux compression, driven by high explosives or by electromagnetic forces, or in a small single turn coil that explodes violently in the process. The single turn coil is usually driven by a very fast high voltage capacitor bank. Special measuring techniques must be developed for use with the different types of pulsed magnets.
