Split-coil magnet arrangement with improved mechanical construction

Abstract

A magnet arrangement with a magnet coil system (M) with two coil systems (C, D) that are each arranged in a container (B, B) positioned around the z axis and that are axially mechanically separated by a split (G), wherein each coil system (C, D) comprises a first (C, D) and a second coil section system (C, D), wherein the first coil section systems (C, D) are exposed to attractive magnetic forces showing toward the split (G) (K, K) and the second coil section systems (C, D), to repulsive magnetic forces showing away from the split (G) (K, K), and containing in the split (G) at least one mechanical structure that withstands compressive loads (E, E) and that supports a part of the attractive magnetic forces (K, K), is characterized in that, in the split (G) within the dimensions of the containers (B, B), a mechanical structure (H) is provided that mechanically withstands tensile loads in the z direction, supports a part of the repulsive magnetic forces in the axial direction (K, K), is connected to the containers (B, B) and holds them together. With the inventive magnet arrangement, the magnetic forces can be better controlled. At the same time, a low-cost, space and weight saving assembly can be implemented.
