Alternative dipole magnets for ISABELLE

Description: A dipole magnet, intended as a possible alternative for the ISABELLE main-ring magnet, was designed at LBL. Three layers of FNAL Doubler/Saver conductor were used. Two 1.3-m-long models were built and tested, both with and without an iron core, and in both helium I and helium II. The training behavior, cyclic energy loss, point of quench initiation, and quench velocity were determined. A central field of 6.5 tesla was obtained in He I (4.4 K), and 7.6 tesla in He II (1.8K).

ISABELLE magnets. A brief description

Description: 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.
