FIG. 1: Schematic view of both cells, clarifying the notations.
FIG. 2: (a) Picture of the first cell (without the insulation and the thermal screen). The “L” structures used for  tem-perature correlation measurements are shown in the channel.
FIG. 3: The correlation function C ( δz, τ ) for various δz in the high power case (235W)
FIG. 5: The spectra of the bridge output, for various Ra values (second cell, P r = 6)
