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 mentioned above, it includes a support body 1 , a longitudinal coil 2 and a horizontal coil 3 . The support body 1 is cylindrical with open upper and lower bottom surfaces, and wire grooves are respectively arranged on the surface of the support body 1 along its circumferential and axial directions for installing the longitudinal coil 2 and the horizontal coil 3. The quantity is determined according to the quantity of longitudinal stitches 2 and horizontal stitches 3 . The longitudinal coil 2 is composed of wires wound circumferentially around the surface of the support 1, and two adjacent longitudinal coils 2 are parallel and communicated through the wires, such as figure 2 shown. The horizontal coil 3 is composed of wires wound around the axial direction of the surface of the support body 1 and the arcs of the upper and lower bottom surfaces, forming a space curved quadrilateral in spa...

Embodiment 2

[0044] The difference between this embodiment and Embodiment 1 is that the number of turns of each longitudinal coil 2 is 1 or more than 1 turn, 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 body 1 is a square tube or other centrally symmetrical cylindrical structure, and the horizontal coil 3 is wound around the groove direction of the surface of the support body 1 and the edge fold lines of the upper and lower bottom surfaces. It is composed of wires and forms a space quadrilateral, hexagon, octagon or other space 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 in particular relates to a three-dimensional magnetic coil with a large uniform area and a manufacturing method thereof. Background technique [0002] Spin-type atomic sensors include NMR gyroscopes, SERF atomic spin gyroscopes and atomic magnetometers. Spin-type atomic sensors control atomic spins through lasers and magnetic fields to achieve precise measurements of angular motion and magnetic fields. [0003] The magnetic field precision control of NMR gyro includes magnetic shielding, magnetic compensation and three-dimensional magnetic field excitation control. The magnetic field generating part of 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 spins, and the higher the achievable precision of atomic sensing. Therefore, the high uniformity of the...
