The relevance of the critical gradient length assumption in electron heat transport is tested against results of electron cyclotron heating (ECH) modulation experiments carried out on ASDEX upgrade, using time-dependent transport simulations.

The findings are consistent with theoretical expectations, as well as with some experimental observations made on Tore Supra and RTP. This global consistency shows the relevance of the physical ingredients involved in the present model, in particular the critical temperature gradient length assumption.
