Problems solved by technology

[0004] Although the traditional Helmholtz three-dimensional coil has a simple structure, its uniformity cannot meet the high uniformity requirements of the longitudinal coil, and it occupies a large volume. The horizontal coil forms a certain seal on the central area, which makes the assembly of the inner parts of the coil inconvenient.

Embodiment 1

[0042] A three-dimensional magnetic coil with a large uniform area, such as figure 1 As described above, the supporting body 1, the longitudinal coil 2 and the transverse coil 3 are included. The supporting body 1 is a cylindrical shape with open upper and lower bottom surfaces. Wire grooves are respectively provided on the surface of the supporting body 1 along the circumferential and axial directions for installing the longitudinal coils 2 and the transverse coils 3. The number depends on the number of longitudinal stitches 2 and transverse stitches 3. The longitudinal coil 2 is composed of a wire wound circumferentially around the surface of the support body 1, and two adjacent longitudinal coils 2 are parallel and connected by the wire, such as figure 2 Shown. The horizontal coil 3 is composed of a wire wound in an arc around the surface axis of the support body 1 and the edges of the upper and lower bottom surfaces, forming a space curved quadrilateral in the space, ima...

Embodiment 2

[0044] The difference between this embodiment and the first embodiment is that the number of turns each of the longitudinal coils 2 is wound is 1 turn or more, and the number of the longitudinal coils 2 is 3, 4 or more.

Embodiment 3

[0046] The difference between this embodiment and embodiment 1 or 2 is that the support 1 is a square tube or other center-symmetrical cylindrical structure, and the horizontal loop 3 is wound around the surface groove of the support 1 and the upper and lower bottom edges. It is composed of wires to form spatial quadrilateral, hexagon, octagon or other spatial polygonal shapes in space.

Abstract

The invention relates to a 3D magnetic coil with a large uniform region and a manufacture method of the 3D magnetic coil, belongs to the technical field of atom sensors, and aims at solving the technical problem that the uniform region of a present 3D coil is not large enough. The 3D magnetic coil with the large uniform region comprises a support body, a vertical coil and a horizontal coil. The invention also provides a coil parameter design method for the 3D magnetic coil with the large uniform region, and the coil parameter design method comprises the steps of calculation of the magnetic field component, calculation of the effective uniformity, optimized solution and consideration of errors. The 3D magnetic coil of the invention includes the large spherical uniform region, the uniformity of the uniform region is high, and the requirement for high uniformity of the vertical coil is met; and according to the coil parameter design method for the high-uniformity 3D coil, optimal parameters can be found according to different structural schemes of the coil, the coil scheme breaks through the traditional manner, and traditional form and performance of the coil are changed.

Description

Technical field [0001] The invention belongs to the technical field of atomic sensors, and specifically relates to a large uniform area three-dimensional magnetic coil and a manufacturing method thereof. Background technique [0002] Spin-type atomic sensors include nuclear magnetic resonance gyroscopes, SERF atomic spin gyroscopes and atomic magnetometers. The spin-type atomic sensor uses laser and magnetic field to manipulate the atomic spin to achieve precise measurement of angular motion and magnetic field. [0003] The precise magnetic field control of the NMR gyroscope includes magnetic shielding, magnetic compensation and three-dimensional magnetic field excitation control. The magnetic field generating component for magnetic compensation and magnetic field excitation control is a three-dimensional magnetic coil. The higher the uniformity of the coil, the more consistent the effect on the atomic spin, and the higher the accuracy of atomic sensing that can be achieved. The...
