Abstract: | An analysis of the experimental data obtained by holographic interferometry in our work 1] makes it possible to explain most
of the observed specific features of the structure and evolution of the plasma sheets developing in a two-dimensional magnetic
field with a null line in a plasma with a low initial degree of ionization (≈10−4). The following two processes are shown to play a key role here: additional gas ionization in an electric field and the peculiarities
of plasma dynamics in a current sheet expanding in time. |
