Abstract: The functioning of a gas-dynamic window designed as an evacuation chamber with orifices 1 mm in diameter for electron-beam extraction from vacuum (10 Pa) into the atmosphere is analyzed. An increase pressure difference is attained due to the ejecting effect arising when the gas flows over an element of the gas-dynamic window with pressure taps in the wall. A method for calculating the area of the pressure taps is presented.
