Popis: A photon counting method has been developed for measuring the current fraction in a D 2 + −He + mixed ion beam. Photons produced by feeding Ar-gas into the beam course are counted through 486 nm- and 389 nm-filters, and the current fraction is instantaneously derived from processing the photon yields with a microcomputer. The sputtering yields of Ta and W obtained by the incidence of pure and mixed ion beams at an energy of 25 keV are demonstrated.
