Some particularities of the formation and flow of the plasma jet of an ablation pulse plasma accelerator with cylindrical geometry

The results of spectroscopic and holographic studies of an ablation (erosion) pulse plasma accelerator with cylindrical geometry are presented with a comparison of data obtained by both methods. The high values of electron concentration, unusual emission of spectral lines, and integral radiation in the beginning of the discharge are explained by the action of the ionization wave. The particularities of the spatial-temporal (radial) distribution of the electron concentration are associated with the vibrational character of the discharge current. The electron concentration was determined by integral spectra and with different time resolution, and with the radial recalculation of intensities and without it, as well as by the pulse holographic interferometry.
