Abstract :
Time-resolved visible emission spectra from the PBFA II argon gas cell were measured in recent light ion beam-target interaction experiments. These emission spectra may be used to study the physics of beam transport and diagnose the cell plasma conditions. We discuss the theoretical analysis of the emission spectra in the wavelength region from 4300 to 4420 Å, where several Aril lines are observed. We examine opacity effects on the emission lines and assess the importance of beam excitation effects. Theoretical spectra are compared with the experimental data.
