Abstract
PURPOSE:To miniaturize a high frequency coil while keeping a uniform space, by winding a plurality of coils each consisting of two up-and-down symmetric saddle- shaped coils around the same length cylinder and setting the linear parts of the saddle- shaped coils to the optimum positions. CONSTITUTION:A high frequency coil is constituted of at least two turn coils 1, 2 composed of two saddle-shaped coils 11, 12 and 21, 22 and the saddle-shaped coils are symmetric with respect to an xy-plane and a yz-plane, and the linear part composed of two conductors parallel to a z-axis and a arc part composed of two arc conductors symmetric to the xy-plane are alternately connected in series and two saddle-shaped coils constituting one turn coil are symmetric with respect to a zx-plane and the linear part of each saddle-shaped coil is present on the same length cylinder. Further, the angle formed by the straight line drawn to the position of the conductor, wherein the position of the xy-plane is present in the first quadrant, among the conductors of four linear parts constituting the turn coils from the origin and a y-axis is set to theta and an angle theta wherein the coefficients of items up to the degrees two times the number of the turn coils among the degree of respective degrees when the distribution of generated flux density on the y-axis is expanded in a power series of the width of y become 0 is set to the optimum angle thetaop and the angle theta of the turn coils is set to a predetermined range containing said optimum angle thetaop.
