Superferric correction magnets for the SSC

Four models of a superferric correction quadrupole magnet were constructed for possible use in the SSC (Superconducting Super Collider); one of them was tested. The design incorporates a coil winding process. This process uses ultrasonic energy to accurately adhere a Kapton-wrapped superconducting wire in a racetrack configuration onto a substrate material 0.010 cm thick. The substrate is subsequently rolled around a frame in much the same way that a jelly roll is made. The use of iron to shape the field improves efficiency and provides a coil package preload. Design parameters and performance data are provided for the quadrupole magnet
