Abstract

MODEL OMITRON is a proposed compact tokamak experiment, characterized by an unusually high value of the toroidal magnetic field. Most of MODEL OMITRON engineering is a faithful reduction by similarity (in true mathematical sense) of the engineering of the parent machine. The building of MODEL OMITRON would allow for full testing of OMITRON engineering, and partial testing of OMITRON physics - at about 5% of the cost that has been estimated for the larger parent machine. In particular, due to the unusually large ohmic power densities in MODEL OMITRON the radial energy flux is reaching values comparable or higher than envisaged of the larger ignition experiments. Consequently, conditions are expected to occur at the plasma border and in the scrape-off layer which are representative of the larger experiments. Since all this will occur under ohmic heating alone, one will hopefully be able to derive an energy transport model that is valid over a wider range of plasma parameters. Finally, by reducing plasma current and/or the toroidal field down to, say, one third or one quarter of the nominal values, additional topics can be tackled, such as: large safety-factor configurations, high beta and long pulse discharges.
