Test Results for HD1, a 16 Tesla$hboxNb_hbox3hboxSn$Dipole Magnet

The Superconducting Magnet Group at Lawrence Berkeley National Laboratory has been developing the technology for using brittle superconductor in high-field accelerator magnets. HD1, the latest in a series of magnets, contains two, double-layer Nb/sub 3/Sn flat racetrack coils. This single-bore dipole configuration, using the highest performance conductor available, was designed and assembled for a...
