Numerous experiments on the plasma-wall interaction problem have been performed with the powerful quasistationary plasma accelerator (QSPA) K-50 device during last decades. These investigations were performed with different target materials (carbon, tungsten, steel etc.) at the different plasma stream parameters. But such problems as, for example, impact of target material on the basic plasma characteristics at the same plasma stream parameters were unsolved. So this paper is summarizing data of researches of plasma shielding layer using different materials of targets. The plasma parameters (peak values) obtained at the longitudinal magnetic field B=0.54 T were as follows: Ne~10¹⁷ cm⁻³ (measured from Hβ linear Stark-effect), Te~2.7 eV, plasma pressure ~16 Bar. Working gas was hydrogen with a small diagnostics dope of nitrogen.
