Abstract

Provided is a manufacturing process of radial superconducting shimming coils. Firstly, the coil contours of the radial superconducting shimming coils (1) unfolded into planes are drawn on a film substrate (3); then, the film substrate (3) is fixed to a winding cylinder (4) in a covering mode; superconducting wires (7) are wound on the basis of the coil contours; the superconducting wires (7) are fixedly supported through epoxy sheets (6) and glass fiber fabric pre-impregnated materials (9) and meanwhile are further reinforced through UV glue (10) in a winding procedure; a plurality of saddle coils of the radial superconducting shimming coils (1) are manufactured in sequence; at last, the saddle coils are heated in a drying oven to be completely solidified, and the winding cylinder (4) is removed so as to obtain a set of radial superconducting shimming coils.

Description

technical field [0001] The invention relates to a manufacturing method of a superconducting coil, in particular to a manufacturing process of a superconducting shim coil for correcting the inhomogeneous component of the radial magnetic field. Background technique [0002] High uniformity superconducting magnet systems are used in nuclear magnetic resonance spectroscopy (NMR), nuclear magnetic resonance imaging (MRI) and other scientific instruments, which can generate a high magnetic field with a certain degree of uniformity in the desired area. Generally, the magnetic field uniformity required by the NMR spectrometer reaches 10 -8 (0.01ppm), the magnetic field uniformity required by MRI and other scientific instruments is about 10 -6 (1ppm). [0003] In general, superconducting magnet systems with high magnetic field uniformity can be obtained by electromagnetic design. However, due to various deviations introduced by processing, manufacturing and assembly, the actual co...
