Abstract
A method for placing an intermediate space in a leaktight and thermally insulating vessel under vacuum. The intermediate space () comprises a gas phase, the gas phase consisting of one or more main chemical species and optionally one or more residual chemical species. The main chemical species has a saturation vapor pressure, at any temperature below 126 K, that is less than the saturation vapor pressure of nitrogen at said temperature below 126 K. The pressure in the intermediate space is at an absolute pressure below a pressure threshold, the pressure threshold being less than the triple point of said or each main chemical species. The residual chemical species is at a partial pressure of less than 0.1 kPa.
