THE PERFORMANCE OF HIGH-FIELD MAGNETS WITH OPTIMIZED INTERNAL REINFORCEMENT

For the performance analysis of pulsed high-field magnets with interna l reinforcement, analytical equations are derived for the optimum dist ribution of the reinforcement in long coils without external reinforce ment. Among others, the relation between the stress in the reinforceme nt, the obtainable magnetic field and the filling factor of the conduc tor are established. By adjusting the amount of reinforcement for each layer of conductor, optimal use is made of the material strength. The refore, this type of magnet is a good candidate for obtaining high mag netic fields up to 100 T. Moreover, it is shown that these magnets giv e the longest pulse duration when used in combination with an energy-l imited high-power pulsed energy source.
