Abstract
A method of manufacturing a solenoidal magnet structure, comprising the steps of providing a collapsible mold in which to wind coils; winding wire into defined positions (88) in the mold to form coils (34); placing a preformed tubular mechanical support structure (102, 120) over the coils (34) so wound; impregnating the coils and bonding them to the mechanical support structure by applying a thermosetting resin and allowing the thermosetting resin to harden; and collapsing the mold and removing the resultant solenoidal magnet structure comprising the resin impregnated coils and the mechanical support structure from the mold as a single solid piece.

A method of manufacturing a solenoidal magnet structure, comprising the steps of:
- providing a preformed tubular mechanical support structure;
- providing a collapsible mold in which to wind coils;
- winding wire into defined positions in the mold to form the coils;
- placing the preformed tubular mechanical support structure over the coils so wound, wherein the preformed tubular mechanical support structure has an inner diameter greater than an outer diameter of some of the coils;
- impregnating the coils and bonding the coils to the mechanical support structure by applying a thermosetting resin and allowing the thermosetting resin to harden;
- and
- collapsing the mold and removing the resultant solenoidal magnet structure comprising the resin impregnated coils and the mechanical support structure from the mold as a single solid piece,
- wherein the preformed tubular mechanical support structure carries an axial split and the step of placing the tubular mechanical support structure over the coils comprises passing the mechanical support structure over the coils with the split open, then at least partially closing the split to reduce the internal diameter of the tubular mechanical support structure, to more closely approximate the outer diameter of the coils.
