Abstract

This work describes and verifies a method for measuring the intensity in the cross-section of a molecular beam. A scheme has been proposed to take into account the background gas’s influence and was tested. Measurements in argon and nitrogen flow demonstrated a direct dependence on the shape, width, and average size of the transverse profile of the molecular beams under conditions of supersonic jet condensation on the Mach number at the entrance to the skimmer.
