Spectroscopic studies of the parameters of plasma jets during their propagation in the background plasma on the PF-3 facility

This paper presents measurement results of neon and helium plasma parameters in axial jets generated in plasma focus discharge. They were obtained in the course of experiments on laboratory modeling of astrophysical jets performed at the PF-3 facility. The plasma concentration was determined according to Stark broadening of spectral lines; the ionization temperature was determined by the average ion charge. The values of the concentration and temperature of jet plasma and background plasma at two distances from the pinch are also presented. In addition, an estimation was made of the heat content losses of the neon and helium jets during their movement through the surrounding medium.

本論文は、プラズマフォーカス放電において生成される軸方向ジェット内のネオンおよびヘリウムプラズマのパラメータの測定結果を提示する。それらは、PF-3施設で実施された天体物理ジェットの実験室モデリングに関する実験の過程で得られた。プラズマ濃度は、スペクトル線のシュタルク広がりに基づいて決定された。電離温度は、平均イオン電荷によって決定された。ピンチから2つの距離におけるジェットプラズマおよび背景プラズマの濃度と温度の値も提示される。さらに、周囲の媒質中を移動する際のネオンおよびヘリウムジェットの熱含有量損失の推定が行われた。
