The density,drift velocity and reproducibility of the plasma produced by a cable plasma gun array have been measured with a charge collector array,The plasma is used to prefill a coaxial plasma-opening switch with a conducting time approaching 0.4us,The reproducibility of the plasma source in subsequent shots is better than 5%.Near the gun nozzle and the opposite electrode,the plasma density amounts to 10^15cm%-3,which is 2 times to 3 times that in the gap between the two coaxial electrodes.A plasma drift velocity of about 2.4cm/μs is observed from the time of flight of the charged particles.Both plasma density and drift velocity increase almost linearly with the rise in charge voltage. 相似文献

1.引言在美国对于伞形天线结构的深入研究已进行了大约二十年,目的是为了获得较大的反射面。因为在空间轨道上,相对来说具有较小的储存空间,载波系统也只能提供有限的能量。自七十年代中期开始,MBB一直从事伞形反射装置的研制工作,他们对卡尔·迈耶公司采用不同材 相似文献
