A PROGRESS REPORT ON THE G-2 STORAGE-RING MAGNET SYSTEM

The 3.1 GeV muon storage ring for the g-2 experiment at Brookhaven Nat ional Laboratory has three large solenoid magnets that form a continuo us 1.451 tesla storage ring dipole with an average beam bend radius of 7.1 meters. In addition to the three storage ring solenoids, there is an inflector dipole with nested dipole coils that create very little stray magnetic field. A superconducting shield on the inflector gets r id of most of the remaining stray flux. This paper reports on the prog ress made on the storage ring solenoid magnet system and the inflector as of June 1995. The results of cryogenic system tests are briefly re ported.
