Abstract :
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
