Abstract
In the reported studies the attention was focused on an analysis of optical spectra of the visible radiation emitted from stainless steel (SS) samples exposed to intense pulses from a ND:YAG laser or pulsed plasma streams produced by a Rod Plasma Injector (RPI) IBIS. Operational regimes of the RPI IBIS facility, which can generate intense deuterium-plasma streams, were studied and corresponding energy fluxes were determined. Optical emission spectra from the laser- or plasma-irradiated SS samples were recorded at different energies supplied. It was proved that intensities of the emitted spectral lines of Fe I and Cr I species depend strongly on deuterium-plasma energy deposited upon the irradiated target.
