A Midsize Tokamak As Fast Track To Burning Plasmas
Authors: E. Mazzucato
Abstract:
This paper describes the conceptual design of a midsize tokamak as a fast track to the investigation of burning plasmas. It is shown that it could reach large values
of energy gain (≥10) with only a modest improvement in confinement over the scaling that was used for designing the International Thermonuclear Experimental
Reactor (ITER). This can be achieved by operating in a low plasma recycling regime that experiments indicate can lead to improved plasma confinement. The
possibility of reaching the necessary conditions of low recycling using a different magnetic divertor from those currently employed in present experiments is
discussed.
