SUPERCONDUCTING MATERIALS AND HIGH MAGNETIC FIELDS
The discovery that Nb/sub 3/Sn remains superconducting in magnetic fields exceeding 88 kgauss while carrying current densities in excess of 100,000 amp/cm/ stimulates the construction of superconducting magnets and the understanding of "hard" superconductivity. The critical current versus magnetic field characteristics of several materials are discussed and the justification of using such measurements on small samples as a basis for magnet design is presented. Nb-- Zr alloys appear useful for magnets capable of fields as large as 80 to 100 kgauss while Nb/sub 3/Sn appears to be useful for fields of 200 kgauss. Fields as large as about 70 kgauss may be generated with Nb/sub 3/Sn magnets and 60 kgauss with Nb- Zr magnets. Fields exceeding 100 kgauss can be attained by augmenting the field produced by a superconducting Nb/sub 3/Sn magnet with the field from a solenoid. (auth)
