Abstract

Electron and ion empirical energy containment times derived from a range of machines are used to construct a O-D power balance model for tokamak discharges. The temperature dependence of the electron containment time is determined from the consideration of neutral injection heated discharges. The model is shown to be in excellent agreement with existing experiments both with and without injection heating and is applied to the next generation of tokamaks. Both the plasma density limit and the B saturation effect observed in high power injection heating experiments are well explained after the addition of radiation losses to the model.
