The paper reports on studies of pulsed plasma-ion streams generated by rod plasma injectors (RPI), and particularly by the IBIS device used for modifications of different materials. Measurements showed that the energy flux density can be from 5 to 25J/cm 2 , and the corresponding pressure—from 0.5 to 2.5bars. Spectroscopic measurements showed that the electron concentration (N e ) amounts to (1.5–3.5)×10 16 cm −3 ; and the electron temperature (T e )—to 1.5–6eV. A study of the interaction of pulsed plasma streams with reversible getters (made of Zr 50 V 50 alloys) showed that a shielding layer has an average density >10 17 cm −3 and it reduces the transmitted energy flux considerably (to 30–60%), what makes possible the shielding of material surfaces.
