Schematics of the nanocalorimeter set-up used for in situ nano-focus X-ray beam measurements. The nanocalorimeter sensor (top) consists of a silicon frame with a thin suspended silicon nitride membrane on which are assembled two pairs of electric heaters (the so-called modulator and guard heaters) as well as six thermopiles connected in series. The calorimetric experiments are realised with the help of a custom-built electronic controller. |
