Abstract

Based on a combination of Alcator scaling and a recent theory on the Murakami density limit, a minimum size Tokamak concept ("Minitor") is proposed. Even if this concept does not aim at alpha particle containment, it has the important goal of reaching plasma core temperatures and Lawson parameter values required for ignition, by ohmic heating alone and under macroscopically stable conditions. The minimized size, and the associated enhancement of the plasma current density, are found to favour high plasma temperatures, average densities, and beta values. The goal of this concept appears to be realizable by relatively modest technical means.
