Abstract

The invention discloses a regular octagonal gradient magnetic field coil, which comprises two regular octagonal coils, wherein the axes of the two regular octagonal coils are coined, and the current directions of the two regular octagonal coils are opposite. A magnetic field with complete linear gradient is formed on the axes, so the coil can solve the problems that the processing difficultly of the coil is high when double-probe optical pumping type and proton type gradient magnetometers are used for calibrating the magnetic induction strength, and the coil is loosened after being used for a long time.

Description

technical field

[0001] The invention relates to a magnetic field coil, in particular to a regular octagonal gradient magnetic field coil capable of generating a uniform magnetic field gradient. Background technique

[0002] Traditional gradient magnetic field generators generally use Helmholtz coils with opposite winding directions to generate gradient magnetic fields, and the size of the gradient magnetic field coil determines the area size of the uniform magnetic field gradient. In the case where it is necessary to calibrate the magnetic induction intensity of the optical pump type, proton type, etc. The volume of the magnetic field coil needs to be greatly increased to meet the requirements of use. However, when making large-scale coils, the circular coil frame is difficult to process, and when the square coil is wound, the coil winding is prone to loosening after long-term use due to uneven force on the wire.
