Abstract
As part of the research in the field of pumping vacuum chambers in the Environmental Electron Microscope, research on supersonic flow through apertures is being carried out at the Department of Electrical and Electronic Technology of the Brno University of Technology in cooperation with the Institute of Scientific Instruments of the CAS. This paper deals with the character and location of shock waves during pumping of vacuum chambers of the experimental chamber as a basis for the forthcoming experiment of mapping the given shock waves using the Schlieren optical method.
