Abstract

Heating in JET The energy confinement properties with strong auxiliary heating are found to be well described by an offset linear law relating the stored energy W to the input power P (W = alpha + beta). The scaling of the energy confinement time T-E with the non-dimensional plasma physics parameters suggests that the underlying transport mechanism is resistive MHD. Electron heat transport is examined in three different ways and shown to be consistent with a local heat flux model with a constant heat diffusion coefficient c-hi. The heating profile and impurity radiation are identified as making a substantial contribution to the degradation in the global energy confinement time with auxiliary heating.
