Abstract
A bakeable electromagnet assembly is made of coils of metal foil either anodized to insulate between turns or separated by a film of Kapton. Cooling plates connected to a source of cooling fluid are used to remove heat. Heat is conducted from the coils to the cooling plates by a powder which is a heat conductor and electrical insulator such as boron nitride. An external shell made of high magnetic permeability material provides a return path for the magnetic field.
