Revised cross section for RHIC dipole magnets

Using the experience gained in designing and building Relativistic Heavy Ion Collider (RHIC) dipole prototype magnets, an improved cross section has been developed. Significant features of this design include the use of only three wedges for field shaping and wedge cross sections which are sectors of an annulus. To aid in the understanding of the actual magnets, one has been sectioned, and detailed mechanical and photographic measurements have been made of the wire positions. A comparison of these measurements with magnetic field measurements is presented. >
