Abstract

The National Superconducting Cyclotron Laboratory (NSCL) is constructing a magnetic spectrometer, the S800, which will consist of two superconducting dipoles and two superconducting quadrupoles. One of the quadrupoles (Q1) has a 24 cm bore and a 34 cm length. The peak gradient of 21 T/m is produced by 2100 turns of 0.7 mm wire operating at 79 A. The maximum stored energy is 64 kJ. The second quadrupole (Q2) has a 42 cm bore and a 30 cm length. Using 0.85 mm wire with 2700 turns operating at 87 A it produces a 6.8 T/m gradient. The stored energy is 146 k.J. A superconducting sextupole is inserted in Q2, which uses 0.3 mm wire and operates at 2 A. All elements are assembled into the same cryostat.
