Superconducting Magnet Facility for Plasma Physics Research

Abstract

A superconducting magnet facility has recently been built and operated as an adjunct to a plasma physics experiment. The facility consists of two superconducting coils in a variable‐spacing, horizontal‐axis, split‐pair configuration. Both coils are enclosed in Dewars that allow a working magnetic field diameter of 17.8 cm at the necks of the magnetic bottle. Each coil is capable of producing a maximum field of 25 kG on its axis. The operating characteristics of the coils, the Dewars, and the facility described are superior to conventional magnets of the same field strength and geometry on grounds of economy, convenience, and flexibility.
