About a New Fusion Reactor Scheme

Abstract

Based on the assumption that the cross-field transport of energy in low-β cylindrical plasmas imbedded in an axial magnetic field is lower than in tokamaks, a fusion reactor scheme is proposed consisting of long straight plasmas connected by short curved sections. It should be capable of producing 13 GW of fusion power when operating in deuterium-tritium at the same plasma density, temperature, and magnetic field of ITER with only a minor improvement in the plasma confinement of the straight sections.
