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.

测量分子束的横向强度分布

本文描述并验证了一种测量分子束横截面强度的方法。提出了一种考虑背景气体影响的方案，并进行了试验。氩气和氮气流的测量结果表明，超声速射流冷凝条件下分子束横向轮廓的形状、宽度和平均尺寸直接依赖于掠流器入口处的马赫数。
