Abstract
The profile constraint resulting from Ohm`s law is used to derive a relationship between the normalized energy content (poloidal or toroidal beta) and the normalized current (l/q) for tokamak discharges. Previous work on this subject, within the framework of the extended neoclassical theory, is extended to include the effect of non-inductive current drive. It is found that the latter, in addition to the plasma refuelling, has a significant influence on the plasma thermal content, although the energy balance is not considered. Agreement is found with available neutral beam injection experiments. The suggestion made previously, that energy confinement may depend more on momentum balance rather than on thermal transport, is given further support.
