The effect of transverse stress on cable-in-conduit conductors (CICC) used for the International Thermonuclear Experimental Reactor (ITER) magnets is discussed. Findings reveal the maximum transverse stress to be 100 MPa on degradation of the cable critical current to roughly 30 percent of its initial value.

Spectrometer magnets for use in satellite and balloon-borne cosmic ray experiments are subject to strict limits on mass and volume. Typically, the particle detectors are mounted adjacent to the outer boundary of the magnet package, rather than within its bore. Optimizing the distribution of ampere-turns radically, in a high alpha, low beta winding cross section places more ampere-turns in closer proximity to the detector volume. In additions, this winding configuration results in lower peak fields and lower stresses in the windings. Utilizing the bore volume for support structure can save a factor of two in structural mass. The resulting magnet package presents a full-diameter flat surface toward the detector space.

The GEM Detector magnet at the Superconducting Super Collider is built in two halves each of which is comprised of 12 single layer superconducting coil modules wound on a 19 m mean diameter and joined with a low resistance lap joint employing the superconducting strands and a copper stabilizer. Each joint half is attached to the sheathed, cable-in-conduit conductor end, and assembly of the mating halves is completed in the field. The target resistance per joint is 5 X [10.sup.-10] [Omega] at an operating current of 50 kA. Details of the joint design, its cooling and results of tests on prototypical sub- and full-scale models using superconducting strands are presented.

The Gammas, Electrons and Muons detector magnet is a key component of the Superconducting Super Collider accelerator. Its features include a solenoid coil made of aluminum-sheathed cable-in-conduit conductors for an operating current of 50 kA. Designed for on-site winding and assembly, it provides a magnetic field of 0.8 T and stores 2.5 GJ of energy. The magnet also employs a natural thermosiphon loop for cooling by thermal radiation.
