Multi-dimensional vector field magnet structure

Abstract

The invention relates to a multi-dimensional vector magnet structure. The structure comprises a first coil, a second coil and / or a third coil, the first coil adopts one or more layers of CCT dipolar coils, and the single-layer CCT coil generates a vector magnetic field with X-direction and Z-direction components at the same time in a magnet aperture area; the second coil adopts one or more layersof CCT dipolar coils, and the single-layer CCT coil generates a vector magnetic field with Y-direction and Z-direction components at the same time in a magnet aperture area; the third coil adopts oneor more conventional coils, and a single conventional coil generates a vector magnetic field distributed along the Z axis in the aperture area of the magnet, wherein the Z axis is supposed to be the central axis direction of the CCT dipolar coil, and the X axis and the Y axis are respectively the pole head directions corresponding to the first coil and the second coil CCT.

Description

Technical field [0001] The present invention relates to a new type of superconducting magnet structure, in particular to a multi-dimensional vector field magnet structure based on a canted solenoid (Canted-Cosin-Theta, CCT for short). Background technique [0002] Vector magnets have important applications in scientific research. The use of magnetic field technology can effectively promote the development of physics, biology, materials and other disciplines. Vector magnets can provide good experimental conditions for them. The use of two-dimensional or three-dimensional vector magnets can be used for positioning research, which provides the possibility for more complex experiments, such as the study of material anisotropy, Hall effect, and single electron tunneling effect. For experimental research that requires a magnetic field in any direction in space, there are two ways to achieve it: fixed magnetic field direction + sample rotation, and fixed sample + magnetic field directio...

AI Technical Summary

Problems solved by technology

A vector field magnet is a magnetic field component that generates any direction in any position in space and in a plane. The coil structure used in the vector field magnets currently on the market, such as figure 1 , figure 2 As shown, the common ones are solenoid coils, racetrack coils or saddle coils, etc. The advantages are simple structure and mature technology, but the disadvantages are large magnet volume, small field area and poor precision.

Due to the limitations of the above coil's own characteristics, the magnet size is too large for large-sized samples
