Adhesively bonded cylindrical magnets comprising annular coils, and method of manufacture thereof

A method for constructing a solenoidal magnet assembly comprising a plurality of axially aligned coils, each comprising a winding impregnated with a resin, comprising:

• for at least one of the coils, forming a thickened crust over the radially outer surface of the winding thereof, and providing through-holes through the crust;
• and
• mechanically restraining the thickened crust, to hold the coils in fixed relative positions to form the magnet assembly.

A method for constructing a solenoidal magnet assembly comprising a plurality of axially aligned coils, each comprising a winding impregnated with a resin, comprising:

• for at least one of the coils, forming a crust over a radially outer surface of the winding thereof, and adhesively bonding a number of lugs to a radially outer surface of the crust;
• and
• mechanically restraining the lugs in fixed relative positions to form the magnet assembly.
