Abstract

The results of conceptual studies of the intensity of vacuum gas evolution of materials used in spacecraft by chemography are presented. This method is based on the fact that the mass of emitted volatile substances actively condensed on the cooled surfaces of the detector plates can be accurately measured at any distance from the surface under study, which makes it possible to predict the intensity of contamination of the optical surfaces of the spacecraft in real operating conditions.
