Microfluidic plane gradient coil of superconducting pulse nuclear magnetic resonance spectrometer, and mounting bracket of microfluidic plane gradient coil

Abstract

The invention discloses a microfluidic plane gradient coil of a superconducting pulse nuclear magnetic resonance spectrometer, and a mounting bracket of the microfluidic plane gradient coil. The gradient coil comprises a first gradient coil circuit board, a second gradient coil circuit board, a ground terminal and a series coaxial line; the two gradient coil circuit boards are mounted in a gradient coil groove of the bracket in a mirror symmetry mode and mutually connected in series to constitute a surface double-flat-plate structure, and the plane of a flat plate is parallel to the directionof a main magnetic field; and the two gradient coil circuit boards each have three layers. The mounting bracket comprises a bracket body and an upper cover plate, and the bracket body comprises a topdisc, a bottom disc and a connecting seat for connecting the top disc with the bottom disc. The microfluidic plane gradient coil is simple in structure, small in resistance value, high in efficiency and good in heat dissipation, and the mounting bracket can provide the sufficient microfluidic space to be matched with the gradient coil.

Description

technical field [0001] The invention relates to a microfluidic plane gradient coil technology for a superconducting pulse nuclear magnetic resonance spectrometer, in particular to a microfluidic plane gradient coil and a mounting bracket for a high-field superconducting pulse nuclear magnetic resonance spectrometer. Background technique [0002] Gradient coil is one of the important components of nuclear magnetic resonance spectrometer, which is mainly used to realize automatic shimming and spectral pulsed gradient field detection technology, so as to obtain better signal quality and more detection information. The gradient coil of the commercial superconducting pulse nuclear magnetic resonance spectrometer is on the top of the probe and wound on the cylindrical mounting bracket outside the radio frequency coil. It is composed of multiple pairs of circular or arc-shaped coils arranged along the direction of the main magnetic field. The coil plane is vertical in the direction...
