本文给出了一种用作等离子体窗口的氩弧等离子体放电的参数，放电电流为1.50A，电压为1.58V。它示出，这种电弧放电允许一个在等离子体窗口的低压端使用相对较低的泵送，以减少在等离子体窗口的低压端的压力几乎380倍。用一个简单的壁稳电弧模型计算了等离子体参数及其空间分布，结果与实验数据吻合较好。它示出，通过等离子体窗口的气体流量的显着减少发生由于等离子体粘度的增加。等离子体窗口点火的改进和它的一些设计方面也被描述。
Parameters of an arc Ar plasma discharge used as a plasma window with a discharge current of ∼50A and a voltage of ∼58V are presented. It is shown that this arc discharge allows one to decrease the pressure at the low pressure end of the plasma window almost 380 times using relatively low pumping at the low pressure end of the plasma window. Calculations of the plasma parameters and their spatial distribution using a simple wall-stabilized arc model showed a satisfactory agreement with the experimentally obtained data. It is shown that a significant decrease in gas flow through the plasma window occurs due to the increase in plasma viscosity. An improvement of the plasma window ignition and some of its design aspects are described as well.
