The paper presents the investigations of plasma streams generated by pulsed plasma gun “Prosvet” operated with
 different gases: krypton (m = 84), nitrogen (m = 14) and helium (m = 4). Contour parameters of working gas spectral
 lines (full intensities and half-widths) are used for determination of spatial distributions of the electron density and
 temperature. Temporal distributions of the spectral lines intensities (both neutrals and ions of working gas), impurity
 spectral lines and continuum intensities are analyzed. Plasma stream velocity was estimated by time-of-flight method
 between two monochromators (MUM) connected with photo-multiplier. Longitudinal distributions of the plasma
 pressure for different time moments and varied distances from the accelerator output have been used for investigation of
 the plasma stream dynamics and study the plasma compression in the focus region for different operational regimes of
 plasma accelerator. Experiments show that operation regime of the accelerator and plasma stream parameters strongly
 depend on the gas atomic mass.
