Today the electron beam is one of the main methods for investigation of rarefied gas flows allowing us to determine a series of local parameters, such as density, partial concentrations, temperatures of internal degrees of freedom, etc. The main idea of the method is to determine gas parameters based on the radiation spectrum excited by a fast electron beam. The above-mentioned spectrum covers the range from X-ray region to visible one. The relation between the intensities excited by electron beam spectra and local gas parameters is provided either theoretically or by a calibration curve.
