Abstract

Production of a large central current hole in tokamak experiments employing off-axis, non-inductive current drive was investigated. The current density was measured to be approximately zero in this region. It was shown that a normal equilibrium cannot exist if the toroidal current inside any flux surface is negative relative to total plasma current.
