Description
Summary:A superconducting dipole, designed for use as a sweeper magnet for nuclear physics experiments, is being constructed by the National High Magnetic Field Laboratory for operation at the National Superconducting Cyclotron Laboratory (NSCL). The magnet consists of two D-shaped NbTi coils and will operate at at a peak mid-plane field of 3.95 T in a gap of 140 mm. Peak field on the conductor will be 6.25 T. The winding pack current density is 143 A/mm2. A multi-particle beam will enter the magnet from the upstream side. The neutrons continue straight through to a neutron detector. The charged particles will be swept 43 degrees on a one meter radius into a mass spectrometer. Status of manufacturing and results of single-coil tests are presented.
