Experimental Characterization of the Electron Heat Transport in Low-Density ASDEX Upgrade Plasmas
The electron heat transport is investigated in ASDEX Upgrade conventional L-mode plasmas with pure electron heating provided by electron-cyclotron heating (ECH) at low density. Under these conditions, steady-state and ECH modulation experiments indicate without ambiguity that electron heat transport exhibits a clear threshold in VT e /T e and also suggest that it has a gyro-Bohm character.
