Abstract

Abstract To determine the local inhomogeneities of a rotating plasma, the method based on microwave refraction was used. The method is based on spectral and correlation analysis of the reflected signals from the rotating plasma layer at normal and inclined microwave incidence. This method allowed us to determine local inhomogeneities of plasma electron density, angles of azimuthal displacement of grooves, and its angular frequency of rotation. Using an additional 4th horn antenna, in contrast to previous works, it was possible to find and analyze two regions with azimuthal inhomogeneities in the rotating plasma. Analysis of the reflected signals shows the presence of four grooves, and the angular frequency of rotation ω = 1.16 × 104 rad/s was also determined.

用微波折射测定旋转等离子体的局部不均匀性

摘要为了确定旋转等离子体的局部不均匀性，采用了基于微波折射的方法。该方法基于对正常和倾斜微波入射下旋转等离子体层反射信号的光谱和相关性分析。这种方法使我们能够确定等离子体电子密度的局部不均匀性、凹槽的方位角位移角及其旋转角频率。与之前的工作相比，使用额外的第四喇叭天线，可以发现并分析旋转等离子体中具有方位角不均匀性的两个区域。对反射信号的分析表明存在四个凹槽，并且还确定了旋转角频率ω=1.16×104rad/s。
