Abstract :
DX dipoles, with an aperture of 18 cm, are located on each side of the six intersection regions of RHIC. All DX dipoles were tested at 4.35 K for quench performance, and trained successfully to at least a 10% margin above the operating field (4.3 T at 6.6 kA). Field quality in these dipoles was measured at room temperature and at 4.35 K using a rotating coil system. The measured harmonics were corrected for offsets of the measuring coil from the magnetic axis, determined by a variety of techniques. All harmonics were found to be within acceptable limits
