Abstract :
Three model superconducting dipole magnets, lm length and having a bore diameter of 76mm, fabricated without epoxy resins or other adhesives, have been built and the first two have been tested in He I and He II. The conductor is the 23-strand Rutherford-type cable used in the Fermilab Doubler/Saver magnets, and is insulated with Mylar and Kapton. The two-layer winding is highly compressed by a system of structural support rings and tapered collets. Little "training" was required. Quench currents greater than 95 percent of "short sample" were obtained in He I with rise-times of 15 to 20 seconds to a central field of 4.6T; 6.0 T in Helium II.
