Abstract
A technique is described for making accurate, localized measurements of the molecular velocity distribution function in rarefied flows of helium. The method is based on the observation of the Doppler profile of a helium emission line that is excited by a beam of energetic electrons. It has been demonstrated experimentally that distribution-function measurements can be obtained. Applicability of this technique to rarefied gas flows and its accuracy are discussed.
