Abstract

Helical magnets have been manufactured of both high Tc and low Tc materials. The helical magnets are manufactured from solid hollow cylinders. A helix is machined in the cylinders, resulting in one-layer solenoids. In this paper, results of a BSCCO 2212 helical magnet are discussed. The magnet has been tested in fields up to 15 T. Stability, quench protection, and critical parameters have been determined. Results of local heating of the magnet, and the resulting quench propagation, have been studied. A distributed method of quench protection has been tested. The results may be used for quench protection of large high-Tc magnets. The details of the testing are described
