Abstract

A 1/2-D model for thermal equilibrium of a thermonuclear plasma with transport described by an empirical global energy confinement time is presented. Ignition in NET and ITER is studied for a number of energy confinement time scaling expressions. Ignited operation of these machines at the design value of the neutron wall load is shown to satisfy both beta and density constraints. The value of the confinement time enhancement factor required for such operation is found to be lower for the recently proposed scaling expressions than it is for the oldest ones. With these new scalings, ignition could be obtained in H-mode in NET and ITER even with relatively flat density profiles.
