All wrapped up in his work, Roy W. Gould, professor of applied physics, gets the feel of a newly constructed device, the tokamak, to be used for experiments concerning heating mechanisms in plasmas--work with applications for the production of energy through nuclear fusion. Coils of the tokamak are wound around a stainless steel vacuum chamber where the plasma heating takes place. These coils create the magnetic fields necessary to produce and confine the plasma.
