Study of plasma jets in plasma focus using the snow-plough model

Development of plasma jets (PJ) generated in plasma focus machine is investigated numerically by the snow-plough model. It is shown that axial speed of PJ, V = 5 × 107 cm/s, few times exceeds the speed of thermal plasma expansion. It means that long distance transportation of plasma jets can be achi...

Description
Summary:Development of plasma jets (PJ) generated in plasma focus machine is investigated numerically by the snow-plough model. It is shown that axial speed of PJ, V = 5 × 107 cm/s, few times exceeds the speed of thermal plasma expansion. It means that long distance transportation of plasma jets can be achieved. Results of calculations are in good agreement with experimental data obtained by interferometry.
