Abstract

During the past year there has been a tremendous growth of interest in the construction of superconducting magnets. This sudden increase of interest may be said to have stemmed directly from the discovery by Kunzler, Buehler, Hsu, and Wernick[1] that Nb3Sn cored wires can be made to carry supercurrent densities in excess of 105 amp/cm2 in applied magnetic fields approaching 100 kgauss. In the two years which have elapsed since these remarkable performance figures were obtained at the Bell Telephone Laboratories, several other compounds and alloys have been found to be attractive for high-field magnet construction, and a number of laboratories[2–7] have achieved superconducting magnets generating fields in the 40 to 70 kgauss range. The construction of such magnets has revealed some interesting and, in some cases, unexpected technological problems which will be the principal subjects of discussion here.
