摘要
本文介绍了一种新颖的角分辨微波相干散射系统。该系统使用了介质分束片,可以方便地进行散射角扫描。利用该系统测量等离子声波的色散关系和系统的波数分辨率,实验证明,该系统适用于研究波长较长的等离子体静电波和不稳定性。
In this paper, an angle-resolved microwave coherent scattering system is described. Dielectric beam splitter was employed in this system, which facilitates the scan of scattering angle. The dispersion relation of ion acoustic wave and the wavenumber resolution of the system have been measured by using this system. It is shown that the system is very suitable for studying long-wavelength electrostatic waves and instabilities in plasma.
