摘要：

The analysis of discharges with strong on- and off-axis ion cyclotron resonance heating shows that the transport of heat in JET is local and diffusive. Discharges with or without pellet injection are considered; in all cases, the electron temperature profile responds to the location of the heating. The total heat flow Q can be described by a local diffusive model of the form Q = -chi(qpsi, \DELTAT(e)\) n(e) DELTAT(e), where chi is proportional to q(psi)1.75 and increases with \DELTAT(e)\. Several forms of the dependence of chi on \DELTAT(e)\ are shown to give a reasonable fit to the data.
