TEST OF 8 SUPERCONDUCTING ARC QUADRUPOLES FOR RHIC

Test results from a group of eight superconducting quadrupoles made at Brookhaven National Laboratory are presented. The magnets have been d esigned for use in the arc regions of the Relativistic Heavy Ion Colli der now under construction at Brookhaven. Novel features of the design include a single-layer coil, the use of injection-molded phenolic for the pole spacers, and a yoke that also serves as a collar. This R&D s eries has been used to verify the magnet quench performance and field quality prior to the start of the production run in industry.
