Abstract

The invention relates to a nuclear magnetic resonance superconducting magnet with a compact coil structure, which comprises a main coil 1-5, an adjusting coil 6-9, a shielding coil 10-12, an anti-electromagnetic interference coil 13-14 and a shimming coil 15-25. The diameter of a superconducting wire is gradually reduced from the main coil 1 to the main coil 5, and the current density is in a graded form. The shimming coil comprises axial coils Z0, Z1, Z2, Z3 and Z4 and radial coils X, Y, ZX, ZY, X2-Y2 and XY, the axial coils Z0, Z2 and Z4 are electromagnetically decoupled from a magnet coil composed of the main coil 1-5, the adjusting coil 6-9 and the shielding coil 10-12, and the axial coils Z0, Z2 and Z4 are electromagnetically decoupled from one another. The anti-electromagnetic interference coils 13 and 14 form a closed loop, so that the superconducting magnet can keep the magnetic field in the central region stable when being interfered by an external magnetic field.

Description

technical field [0001] The invention relates to a nuclear magnetic resonance superconducting magnet with a compact coil structure. Background technique [0002] The magnet is an important part of the NMR system. The strength of the magnetic field generated by the magnet directly affects the resolution and sensitivity of the NMR, which in turn affects the ability to detect molecular structure information. Generally speaking, the higher the magnetic field strength of the NMR magnet, the higher the resolution and sensitivity of the corresponding atomic spectrum signal. In this way, molecular structure information or extremely small element information that is difficult to obtain under low magnetic field conditions may be obtained under high field conditions. With the help of the high current-carrying capacity of superconducting wires, superconducting magnets can generate high-intensity magnetic fields, significantly improve the resolution and sensitivity of nuclear magnetic re...
