  "description" : "A new model for the electron temperature profile resilience in the outer half of tokamak plasmas is proposed and investigated. It is shown that introducing a negative feedback term into the scaling of the electron heat diffusivity {chi}{sub e}(r) = {chi}{sub ee}(r)(1-{alpha}a{sup 2}/T{sub eo} d{sup 2}T{sub e}/dr{sup 2}) with {alpha} > or {approx} 3 results in the observed T{sub e} profile stiffness against variations of the density and heating profiles. In addition, the feedback by itself yields the measured approximately linear T{sub e}(r) shape for r/a > or {approx} 0.5 in contrast to previous profile constraining models. (orig.). 6 figs.",
