“…We have investigated some high-strength conductors [2], [3] and reinforcement materials [1]. This paper reports results of a high strength CuNb conductor, a multiphase alloy (MP35N), and a reinforcement composite consisting of Zylon, a high-strength fiber, in combination with MP35N and high-strength epoxy.…”

“…Therefore, for pulsed magnet applications, cold work to 65% appears to be the optimum fabrication approach for deformation; 2) The strengthening of MP35N by aging has to follow cold work. In as-deformed samples, strain hardening is attributed to formation of extremely nanosized platelets (about 1 nm thick), and high density of dislocations [1]. The habit planes of the platelets are in {111}.…”

“…Studies have shown that an optimized magnet could generate a magnetic field of 100 T with an energy of only 2 MJ [1]. Such a magnet would have a relatively small size (20 kg) and, therefore would be very cost effective.…”

“…It is possible to reduce the geometric dimensions of the magnet linearly by a factor of 2. According to scaling laws [1] dimensions reduce proportionally to , and the energy requirement reduces proportional to the volume, i.e., with the 3rd power, to about 220 kJ. We propose to build such a small magnet as a first step, as it involves considerable cost savings.…”

The development of improved conductors and reinforcement materials is instrumental for the achievement of ultra-high fields with monolithic magnets. They have the advantage that there is no coupling between the coils of the traditional two-coil systems, and that the magnet can be built much smaller, and it has longer pulse times. The fields that can be achieved are determined by the strain limitation of the conductor, and the strength and stiffness of the reinforcement. We have investigated the material requirements for this type of magnet to define the objectives for material development. It follows that future material development activities for reliable 100 T magnets should focus on conductors with the following specifications (all values are at 77 K): a) Ultimate conductor strength of 1.2 GPa, b) Conductivity of 500 percent IACS, c) 10 percent strain to failure, d) Fatigue strength of 1 GPa at about 5000 full load cycles from tensile stress at peak pulse to compressive stress after the pulse of about 0.6 GPa. It is equally important to improve the reinforcement materials. At the NHMFL, we use with great success a combination of Zylon fiber and MP35N superalloy. We have increased the isotropic strength of MP35N at 77 K to 2.6 GPa (modulus 240 GPa), and are working on further improvements.Index Terms-Fatigue strength, high-strength conductors, highstrength materials, monocoil pulse magnets, pulse magnets, reinforcement materials.

“…To date, resistive magnets have been built attaining fields up to 33 T dc [3]. Short pulse (10-20 ms), non-destructive magnets have attained fields in the 70-80 T range [4], and 100 T magnets are being built [5]. Destructive pulsed magnets have attained fields up to ∼2800 T during pulses of several microseconds [6].…”

The world’s highest-field dc magnets have, for roughly the past thirty years, consisted of resistive-superconducting hybrid magnets. These magnets use superconducting technology for the outer coils, where the magnetic field is moderate, and resistive-magnet technology for the inner coils, where the field is highest. In such a configuration, higher fields are attained than is possible with purely superconducting magnet technology, and lower lifetime (capital and operating) costs are attained than with a purely resistive magnet. The resistive coils of these magnets represent the pinnacle of high-field resistive-magnet technology and have been the focus of much of the resistive magnet technology development over the past thirty years. The evolution of high-field resistive magnet technology is presented, focusing on the development of hybrid inserts.
