圆柱形和倒圆柱形磁支撑直流放电的研究
A study of magnetically-supported dc discharge in cylindrical and inverted cyclindrical configuration
摘要：
本文研究了同轴圆柱形磁支撑直流放电的随机涨落。在该系统中，电场具有径向方向，而磁场施加轴向。放电容器的长度为12厘米。工作气体通常为氩气，压力为几Pa，磁场为10-50 mT。的贡献描述了实验结果-频率和相位分析的不稳定性，我们在我们的实验系统中检测到的常规和倒置磁控管配置。我们还提出了直流放电的二维PIC模型的条件下，这可以在实验装置实现。
英文摘要：
We have investigated apparently stochastic fluctuations of magnetically-supported dc discharge in cylindrical coaxial configuration. In the system the electric field had radial direction while the magnetic field was applied axially. The discharge vessel length was 12 centimetres. Working gas was typically argon at pressure of several Pa, magnetic field 10-50 mT. The contribution describes experimental results - frequency and phase analysis of the instabilities, which we detected in our experimental system in both the conventional and inverted magnetron configurations. We bring also 2-D PIC model of the dc discharge under conditions, which can be achieved in the experimental apparatus.
