Abstract

A superconducting Ioffe magnetic trap is designed, built and characterized. The trap consists of four racetrack-shaped quadrupole coils and two solenoid assemblies. Coils are wet wound with multifilament copper-clad NgTi superconducting wire embedded in an epoxy/fiberglass matrix and are mechanically held with compression collars onto a titanium form. Prestressing of the quadrupole coils at low temperature is provided by constructing the collars from aluminum, a material that has a large coefficient of thermal expansion. The magnet bore diameter is 105 mm, the trap depth is 1.1 T at 4.2 K. Design, construction and performance of the trap and its quench protection circuit are reported.
