ENERGY CONFINEMENT WITH OHMIC AND STRONG AUXILIARY HEATING IN JET
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.
