Design and scaling of a simple and inexpensive fusion ignition experiment

Summary form only given. The basic characteristics of the ignited plasma in IGNITEX were obtained from considerations of thermal energy production and losses in the discharge. Ample ignition, margin, path to ignition conditions. and thermal runaway control were shown. A high possibility of ignition was obtained with the IGNITEX characteristics. Ignition is possible far from marginal stability, with ohmic heating alone and without the need for enhanced energy confinement. The high level of stress present in the magnet system can be tolerated by a single-turn toroidal coil with a very high filling factor. Impedance matching requirements are met by homopolar generators. Iron-core and reinforced epoxy-composite flywheel technologies are used for the power supplies. Nuclear shielding requirements for the primary shielding and for the diagnostic system have been estimated. The first wall system was studied. Scaling relationships for the principal design characteristics of an ignition, single-turn tokamak have been obtained. The scalings were used to analyze the small and large versions of the IGNITEX experiment
