Abstract
An in-situ positron analysis system has been developed for positron annihilation lifetime spectroscopy during ion beam irradiation. An electron linear accelerator was used to produce a slow positron beam for this system. Positron lifetime spectroscopy of SiO2/Si and annealed pure Fe samples was successfully demonstrated during simultaneous irradiation with a 150 keV Ar+ beam. The lifetime spectra changed with increasing ion dose, indicating a decrease in ortho-positronium intensity (SiO2) and the decrease in positron diffusion length (Fe).
