Schematics of the pressure cell. (a) Side view. The nucleus, a single crystalline Al2O3 ring shown in light blue, is secured by two stainless steel flanges. The black arrows indicate the direction of the incident and reflected beams. For a better visualization the relevant angles are exaggerated. The Cu pipes, used for varying the temperature, are spiraled around both stainless steel flanges and are shown in orange. (b) Section view. Liquid samples are introduced into the nucleus via a 1 mm inlet. A pressure-tight and variable-height mechanism, that allows the introduction of solid samples via a circular aperture machined into the bottom flange, is circled in red (see text). |
