Description
Design and performance of a heatable, easily alignable Pt-nozzle source (pinhole) are described, providing sufficient O2 intensity in both pure gas and seeded beam operation for crossed beam experiments with metal atoms and mass spectrometric detection. At the chosen skimmer-nozzle distance, nozzle Knudsen numbers around K/subn/approx. =10-2 gave optimum velocity ratio and intensity for all gas mixtures at nozzle temperatures from 300 to 1300 K. The oven design is particularly suited for effusive metal beams at T<1200 K
