摘要:

本文对实验室等离子体中剪切阿尔文波之间的非线性相互作用进行了实验研究。由谐振腔产生的两个Alfvén波被观察到一起拍频,在拍频处驱动低频非线性伪模。伪模散射阿尔芬波,产生一系列边带。观察到的相互作用非常强,驱动伪模的归一化振幅与相互作用的阿尔文波的归一化磁场振幅($δB/B$)相当。

英文摘要:

An experimental investigation of nonlinear interactions between shear Alfvén waves in a laboratory plasma is presented. Two Alfvén waves, generated by a resonant cavity, are observed to beat together, driving a low frequency nonlinear psuedo-mode at the beat frequency. The psuedo-mode then scatters the Alfvén waves, generating a series of sidebands. The observed interaction is very strong, with the normalized amplitude of the driven psuedo-mode comparable to the normalized magnetic field amplitude ($δB/B$) of the interacting Alfvén waves.
