The paper presents results of experimental research on emission of the visible radiation (VR) from intense deuterium plasma streams propagating freely within a vacuum chamber or interacting with silicon-carbide (SiC) targets. The investigated pulsed plasma streams were generated by high-current discharges realized within two facilities of the Plasma-Focus (PF) type, i.e. within the PF-1000U facility operated at the IFPiLM and the PF-360U device operated at the NCBJ. Detailed measurements have been carried out using optical emission spectroscopy (OES) technique. Parameters of plasma were estimated from the D line only. Structural changes of the irradiated SiC targets were analyzed by means of a scanning electron microscope (SEM) and energy dispersive X-ray spectrometer (EDS). © 2014, National Science Center, Kharkov Institute of Physics and Technology.
