等离子体波动的测量对于研究通过形成等离子体限制电势来改善等离子体限制非常重要。利用微波通过干涉法、反射法和夫琅和费衍射法等方法观察密度波动。我们构建了一种新型多通道微波干涉仪来测量单次等离子体发射中的等离子体密度和波动径向分布。我们使用多通道微波干涉仪成功测量了单次等离子体发射中的时间相关密度和线积分密度涨落径向分布。因此，我们开发了一种有用的工具，用于研究通过形成等离子体限制电势来改善等离子体限制。
Measurement of fluctuation in plasma is important for studying the improvement in plasma confinement by the formation of the plasma confinement potential. The density fluctuation is observed by microwaves by methods such as interferometry, reflectometry and Fraunhofer diffraction method. We have constructed a new multichannel microwave interferometer to measure the plasma density and fluctuation radial profiles in a single plasma shot. We successfully measured the time-dependent density and line-integrated density fluctuation radial profiles in a single plasma shot using the multichannel microwave interferometer. Thus, we have developed a useful tool for studying the improvement in plasma confinement by the formation of plasma confinement potential.
