Abstract

The invention discloses a superconducting coil and a manufacturing method thereof. The method comprises the steps of integrally performing resin immersion on the superconducting coil, wherein certain gaps are arranged between each circle and layer of wound superconducting wires; and heating and solidifying resin to fix positions of the superconducting wires. According to the method, the resin immersion is performed on the superconducting coil in a vacuum environment, so that the resin can be distributed uniformly, and a resin immersion success rate can be raised. Distances between each circle of superconducting wires and between each layer of superconducting wires are preset distances during winding of the superconducting wires, so that the distances are controlled, and a requirement of magnetic resonance imaging for the uniformity of a basic magnetic field of the superconducting coil can be met.

Description

technical field [0001] The invention relates to the electromagnetic field, in particular to a superconducting coil and a manufacturing method thereof. Background technique [0002] Magnetic resonance imaging has become one of the main means of modern medical imaging, and its imaging quality depends to a large extent on the uniformity of the basic magnetic field in the central imaging area of ​​the superconducting coil. Therefore, the structural design and subsequent assembly of the superconducting coil very important. [0003] The current superconducting coils are all superconducting wires tightly wound on the spool to form a multi-layer superconducting wire layer; the superconducting wires between the superconducting wire layers are in direct contact, and the superconducting wires in this state are in the current-carrying state. There will be a certain repulsive force between them, which will cause the position of the superconducting wire to move, thereby changing the posi...
