Neutron diffraction patterns from silver phosphate (AgPO3), AgI-AgPO3 and Ag2S-AgPO3 glasses were analysed by the Reverse Monte-Carlo method. The diffraction patterns were collected on the HIT-II spectrometer at KENS up to Q = 50 Å- 1. The derived structural models of the salt-doped glasses were compared to AgPO3 glass to correlate features of the atomic and molecular structure with observed superionic conduction in these glasses. A structural model based on extended chains of PO4 tetrahedra, as reported previously by other researchers, provides a solid basis for all these glasses. The analysis indicates a strengthening of the Ag-Ag correlations and contrasting changes in the Ag-O correlations in the doped glasses. We also conclude that S largely displaces non-bridging O in the PO4 tetrahedra in Ag2S-AgPO3 glass.
