Self-consistent electron and ion flows in a fast Z-pinch

Experimental study of the spatial structure of high-energy ion sources in micropinch

“…The presence of a singularity in the magnetic probe signal in the current ramp up phase indicates the development of the pinching pro cess in the discharge channel [11]. Analysis of pinhole images shows that the mechanism of radiative com pression efficiently operates in each discharge (up to…”

“…The experiments were carried out using a high cur rent vacuum spark device [11]. The discharge was ini tiated in a vacuum chamber in the erosion products of the electrode material (iron).…”

Development of the electron acceleration process and dynamics of micropinch plasma

“…The above-mentioned values of voltage surges as a result of the arising anomalous resistance of the pinch plasma are predicted by numerical evaluations made within the model of radiation compression [12] and matched with the measured energies of 10 4 −3 • 10 5 eV emitted from the constriction plasma in the axial direction of fast epithermal electrons. Measurements were conducted by direct recording of the epithermal electrons flux [12][13][14] and by analysis of continuous x-ray radiation spectra [11,15,16].…”

A Method for Investigating Nanosecond Processes in Micropinch Discharge Plasma

“…They can be associated, e.g., with the formation of a directed plasma stream moving along the discharge axis. There is experimental evidence that the micropinch formation region moves along the discharge axis from the inner electrode to the outer one and, in addition, the axial stream of plasma that outflows from the microstretch region has a noticeably higher velocity in the direction of the outer electrode than in the opposite direction (in the direction of the inner electrode) [12][13][14]. The rate of the plasma outflow from the microst-…”
