Summary

This biennial conference is focused on the formation of spectral line profiles and with their use for diagnostic purposes. The line profiles are employed as powerful diagnostic tools for various media, such as neutral gases, technological gas discharges, magnetically confined plasmas for fusion, laser- and z-pinch-produced plasmas, astrophysical plasmas, planetary atmospheres.
