摘要
A method has been developed and is described for measuring the flux of a beam of hyperthermal oxygen atoms using a quadrupole mass spectrometer. The accuracy of this method has been assessed by adsorbing the O atom flux on a Au surface for a specified period of time and quantifying the adsorbed amount using ion scattering spectroscopy and by estimating the oxygen-atom flux from the electron stimulated desorption parameters used to produce the oxygen-atom beam.
