The purpose of this paper is to discuss the 24 Tesla MINIMARS choke coil configuration. It is a hybrid design consisting of a superconducting background coil and a normal-conducting insert coil. Recent technology advances, use of superalloy reinforcement materials, and current density grading allow the design of coils that are more compact and operate at higher fields than past designs.
