“…In our case, when a high-voltage pulse is applied to the discharge tube, an electron beam is injected that produces a plasma channel, which causes the development of a discharge over the entire cross section of the tube, and not only at its periphery. The estimates for this type of the discharge were carried out in the MHD approximation [3], which showed a smoother current distribution over the discharge at a relatively lower pinching level and lower plasma temperature. An experimental setup was designed to study the dynamics of the Z-pinch plasma with the initiation of an electron beam discharge in the Laboratory of High-Energy Density in a Substance at the Institute for Theoretical and Experimental Physics [3][4][5].…”

Currently, work is underway to create laser accelerators with beam focusing by plasma lenses. For effective focusing, it is necessary to investigate at which initiation of breakdown a discharge forms with a more uniform distribution of current density. Our studies have shown that the plasma distribution is uniform over a longer period of time, including the region of maximum current, if the discharge is initiated by an electron beam.

We study the gas discharge process under conditions when a relativistic electron beam is injected into the discharge tube after applying a high-voltage pulse. As a result, a plasma channel is created, a breakdown occurs, and a discharge develops. Comparative experiments were performed at different gas pressures under discharge conditions with and without electron beam initiation. They showed significant differences, especially during pinching and further development of the discharge.
