Three distinct, yet connected areas of non-linear interactions in plasma physics are studied experimentally: Langmuir turbulence in unmagnetized plasmas, non-linear waves and instabilities in non-neutral plasmas, and non-linear whistler wave-particle interactions. The validity and limitations of weak turbulence theory and the transition from weak to strong Langmuir turbulence will be investigated. Nonlinear wave particle interactions in the magnetosphere will be simulated and anisotropic whistler instabilities will be studied. Non-neutral plasmas will be investigated in a regime where non-linear interactions, such as ponderomotive force effects, can be explored. The research will lead to improved understanding of fundamental processes in non-linear plasma environments.

三个不同的，但连接的非线性区域 等离子体物理学中的相互作用进行了实验研究： 非磁化等离子体中的朗缪尔湍流，非线性波 和非中性等离子体中的不稳定性， 哨声波粒相互作用 弱湍流理论的有效性和局限性 以及从弱到强的朗缪尔湍流 将进行调查。 非线性波粒相互作用 磁层将被模拟和各向异性哨声 将研究不稳定性。 非中性等离子体将是 在一个非线性相互作用的制度，如 作为有质动力效应，可以进行探索。 研究 将有助于我们更好地理解 在非线性等离子体环境中。
