Superconducting beamline elements for the NSCL spectrograph

The superconducting beamline elements for a magnetic spectrometer at the National Superconducting Cyclotron Laboratory are being constructed. There are four dipoles, which produce a peak field of 1.7 T in a 7 cm gap, and fifteen quadrupoles, which have peak gradients of 25 T/m in a 20 cm diameter bore. A quadrupole has been tested to higher than the required current. All of the devices are being assembled into their cryostats.<
