Patent ID: 7849587

Claim:
A method for manufacturing a solenoidal magnet structure having a longitudinal axis, comprising the steps of: (a) providing a collapsible mold comprising a collapsible mandrel with at least one removable section thereof, in which to wind at least one coil of said solenoidal magnet structure; (b) forming a mechanical support structure by placing staves at defined positions in said mold parallel to said longitudinal axis; (c) forming said at least one coil by winding wire over said mechanical support structure in said mold; (d) impregnating said at least one coil and said mechanical support structure with a thermosetting resin; (e) allowing said thermosetting resin to harden; and (f) collapsing said mold by disassembling said mold and removing said section from an interior of a resulting solenoidal magnet structure comprising the resin-impregnated at least one coil and the mechanical support structure, and removing said resulting solenoidal magnet structure from said mold as a single solid piece.
