Title: Construction challenges and solutions in TAMU3, a 14 T stress-managed Nb{sub 3}Sn dipole

The Accelerator Research Laboratory at Texas A and M University is nearing completion of a Nb{sub 3}Sn dipole that incorporates stress management directly in its windings. The windings utilize graded-cross-section cable made from 54/61 (54 out of a 61 subelement hexagonal pattern) Restacked Rod Processed® Nb{sub 3}Sn/Cu conductor and fine-filament S-2 glass fabric insulation. Coil heat treatment and associated differential expansions have brought about some tin leakage, highresistance electrical shorts, and coil gaps. TAMU3b impregnation successfully increased the coil-to-ground resistance. Quench protection in TAMU3 was simulated using QUENCH. The tests of TAMU3 should provide the first examination of stress management at field intensities greater than 12 T.
