Abstract

A novel construction of a superconductive coil system, having sufficient coupling strength and stiffness and being easy to assemble, is disclosed. A coil retainer of a stiffened cylindrical shell is divided into two parts for receiving coils and spacers. The inner circumference sides of the adjoining portions of the two parts form a dividing surface consisting of a plane extending longitudinally and are coupled with bolts having their axes directed in the circumferential direction. The outer circumference sides of the same adjoining portions form comb teeth meshed with each other and keyways extending longitudinally along the outer surface of the same comb teeth, and are coupled by keys inserted into the keyways and having their axes directed in the longitudinal direction. Preferably, left and right coils having profiles of the shape of divided pieces obtained by longitudinally dividing a cylinder, and upper and lower spaces sandwiched between the coils and having profiles of the shape of the remaining divided pieces, are disposed within the coil retainer, with outer circumference of the coils and spacers kept constrained.
