This paper presents preliminary results for a new design of a pulsed linear plasma device that generates electromagnetic plasma propulsion. The current sheath dynamics and the plasma propulsion along an extension tube have been studied. Breakdown of helium gas occurs between coaxial electrodes when applying a high-voltage pulse. This paper presents measurements with a number of probes, as well as camera images of the plasma propagation. A plasma is ejected and fills a 40 cm length extension tube. Additionally, the measurements show that the length of the propelled plasma column and its intensity inside the expansion tube is increased by increasing the charging voltage, while the plasma propulsion current is decreased along the extension tube. It is noted that a lower critical time;4.7 μ s, is needed to ionize the gas and form the plasma current sheath.

低能线性等离子推进装置的实验研究

本文介绍了产生电磁等离子体推进的脉冲线性等离子体设备的新设计的初步结果。已经研究了沿延伸管的当前护套动力学和等离子体推进。施加高压脉冲时，同轴电极之间会发生氦气分解。本文介绍了许多探头的测量结果以及等离子传播的相机图像。血浆被排出并充满40 cm长的延长管。另外，测量结果表明，通过增加充电电压，可推动等离子柱的长度及其在膨胀管内部的强度，而沿推进管的等离子体推进电流则减小。值得注意的是，较低的临界时间； 4.7μs，
