A Novel Epoxy-Free Construction Method for Fabricating Dipole Magnets and Test Results
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.

Magnetic measurements at Lawrence Berkeley Laboratory
Recent magnetic measurement activities at LBL have been concentrated in two separate areas, electromagnets and permanent magnets for the Advanced Light Source (ALS), and superconducting magnets for the Superconducting Super Collider Laboratory (SSCL). A survey of the many different measurement systems is presented. These include AC magnetic measurements of an ALS booster dipole engineering model magnet, dipole moment measurements of permanent magnet blocks for ALS wigglers and undulators, permeability measurements of samples destined for wiggler and undulator poles, harmonic error analysis of SSC one-meter model dipoles and quadrupoles and five-meter long SSC prototype quadrupoles, harmonic error analysis of ALS dipoles, quadrupoles, and sextupoles, precision Hall probe mapping of ALS storage ring combined function magnets, and the design of the ALS insertion device magnetic mapping system. A Unix-based data acquisition system that is being developed for the SSC is also described. Probes used for magnetic measurements include Helmholtz coils, integral coils, point coils, bucking harmonic analysis coils, several different types of Hall probes, and nuclear magnetic resonance magnetometers. >
