Abstract

The invention relates to a coil system (30, 40, 50) for generating a homogeneous magnetic field, comprising a coil assembly (2), each assembly consisting of at least two coils (S1, S2, S3), the respective windings (W1, W-2, W3) of which span rotationally symmetrical faces lying plane-parallel to one another having different sizes and a common axis of rotation running perpendicularly to the faces,forming a coil axis (4), wherein a current can flow in the opposite direction through at least one of the coils (S1, S2, S3), characterized by at least two coil assemblies (2), wherein the coils (S1,S2, S3) of each coil assembly (2) are located within and oriented plane-parallel to the base of a generating pyramid, the tip of which coincides with the centre of a regular convex polyhedron and thebase surface of which is identical to one such face of the convex polyhedron, on which the projection of the pyramid tip onto the pyramid base surface coincides with the centre of the pyramid base surface.

Description

technical field [0001] The invention relates to a coil system for generating a homogeneous magnetic field, the coil system comprising coil assemblies, each coil assembly consisting of at least two coils, the respective windings of which coils form a plane-parallel rotationally symmetrical surface, the rotationally symmetrical surface Current flows in opposite directions through at least one of said coils having different dimensions and a common axis of rotation being the axis of the coils extending perpendicular to the surface. Background technique [0002] A coil system based on such a coil assembly realizes a coil system suitable for generating a uniform magnetic field by adding the coil assembly. In particular, the coil system is suitable for generating a homogeneous field in any direction if their coil axes are orthogonal to each other. The magnetic field, which has a high degree of homogeneity in the center of the coil system, is practically invariant with respect to s...
