摘要：

A superconducting system with a field strength of about 50 kOe in a 20 cm bore is described. The system, with a total weight of 260 kg, consists of two coils divided into radial and axial sections; the axial gap between coils can be changed. The winding is made of stabilized copper strip into which wires of Nb-50%Zr alloy are inserted. In order to minimize the total weight as well as the weight of superconductor the winding is self consistent in regard to critical current and to stability. The number of wires ranges from 20 to 4 and the cross section of the strip from 6.5 to 4 mm2 respectively. In preliminary tests a field of 47 kOe was achieved at a stable current of 575 A (without superconducting-to-normal transition). © 1969.
