Abstract :
A two layer superconducting dipole magnet-D19H, with a Nb/sub 3/Sn inner layer and a NbTi outer layer was designed, constructed and tested. The 50 mm bore inner layer of an existing NbTi dipole magnet (D19A), has been removed and replaced with a Nb/sub 3/Sn coil. The outer NbTi coil, collars, iron yoke, ring, collets and outer skin from the disassembled D19A magnet have all been reused. Employing glass insulated cable with aluminum-bronze poles and end spacers the Nb/sub 3/Sn coil was reacted at 660/spl deg/C for 240 hours and fully epoxy impregnated. The design and construction of the magnet are described and test results reported elsewhere in these proceedings.
