Abstract
A new procedure for inferring χ[subscript i,e] in the plasma edge from experimental data and
integrated modeling code calculations has been developed which takes into account
atomic physics and radiation effects and convective as well as conductive heat flux
profiles. Application to DIII-D shots indicates that the sharp temperature gradient
pedestal region may be caused as much, if not more, by an increase (with radius) of the
conductive heat flux as by a decrease of the thermal transport coefficient. Inferred χ[subscript i,e][superscript exp] are compared with theoretical predictions.
