S. Askenazy et al., THE PERFORMANCE OF HIGH-FIELD MAGNETS WITH OPTIMIZED INTERNAL REINFORCEMENT, Measurement science & technology, 7(4), 1996, pp. 680-685
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.
