Use of a spacer between layered coil sections in a superconducting magnet structure

A method for magnetic coil design comprising the steps of:

• executing one or more magnetic design analysis routines based on one or more magnet design inputs, wherein the magnet design inputs comprise performance characteristics for a target magnetic field;
• obtaining as an output of the one or more magnetic design analysis routines a respective geometry of each magnetic coil of a plurality of coils of a magnetic coil structure to be fabricated;
• and
• based on the respective geometry of each magnetic coil of the plurality of coils, determining a geometry of two or more radial gaps to be formed within one or more magnetic coils of the plurality of coils so as to maintain magnetic field homogeneity of the magnetic coil structure during operation.

A method for winding a magnetic coil structure, the method comprising:

• for a first magnetic coil of the magnetic coil structure, winding a first coil segment having a first inner diameter and a first outer diameter;
• measuring one or both of a thickness of the first coil segment or the first outer diameter of the first coil segment;
• based on the thickness or the first outer diameter, determining a thickness of a radial gap to be formed in the first coil segment;
• forming a radial spacer in the radial gap, wherein thickness of the radial spacer corresponds to the radial gap thickness;
• winding a second coil segment over the radial spacer, wherein the second coil segment has a second inner diameter and a second outer diameter;
• and
• forming two or more radial gaps and corresponding radial spacers in one or more pairs of coils of the magnetic coil structure to maintain magnetic field homogeneity of the magnetic coil structure during operation.
