Abstract
A test of a new model for the low-to-high (L-H) mode power threshold, based on the
stabilization of edge thermal instabilities, is made by comparison with a set of DIII-D [J. L.
Luxon, Nucl. Fusion, 42, 614, 2002] discharges at times just prior to a L-H transition.
Agreement is found between the measured power crossing the separatrix just prior to the L-H
transition and the predicted power threshold for the stabilization of transport enhancing thermal
instabilities.
