ISABELLE magnets. A brief description

Abstract

The modified ISABELLE dipole design, adopted in the fall of 1981, is briefly described, and the assembly procedure and performance of initial prototype magnets summarized. The new magnets incorporate a cabled superconductor wound in a two-layer coil configuration, supported by a laminated split iron yoke. In all cases the prototype magnets reach short sample performance on the first quench, and exhibit virtually no training; eddy current effects are negligible as well
