概要
- 論文の詳細を見る
Pulsed molecular beams of about 5 msec duration of room temperature argon from an electromagnetic valve are examined, and their intensities, conditions for the optimum nozzle-skimmer distances and source pressures, with a flat beam intensity, and their speed ratios were measured. The optimum conditions were obtained for the Knudsen number based on the skimmer orifice Kn_s=2-6. The dependence of the beam intensity for the optimum conditions on the source pressure agrees very well with a modified expression given here based on the sudden freezing model. The attainable speed ratios agree with the semi-empirical relation of Anderson and Fenn.
