Ignition and burn in electric tokamaks at low magnetic fields

It is argued that vast improvements in the physics and implementation of a tokamak reactor core are possible if one (1) operates at unity beta to exclude the magnetic field from a large fraction of the plasma volume, (2) adopts a large enough aspect ratio for equilibrium control, (3) chooses a magnetic geometry with a volumetric bell-like 'magnetic centre' instead of the more common magnetic axis, and (4) uses rapid poloidal flow to maintain a dynamic equilibrium. The flows are needed for simultaneously reducing the effects of plasma granularity (finite gyroradius effects) on confinement and stabilizing the low n number MHD modes. These elements define the 'electric' aspect of the tokamak both at the microscopic equilibrium level and the H mode type global confinement level. When combined with the omnigenous magnetic surfaces (closed mod-B surfaces) of a high beta plasma (PALUMBO, D., Nuovo Cim. 53B (1967) 507), nearly classical confinement in a plasma with otherwise significant Larmor scale granularity is predicted. Ignition and burn in a D-T plasma would then be possible at B-phi similar to 2 T and I-p similar to 4 MA, while a device with ITER-like parameters would be capable of burning advanced fuels.
