Wong Study of Collapse processes in strong electromagnetic (EM) wave interactions with magnetized and unmagnetized plasmas. The program consists of: the search for caviton collapse generated by EM waves at the resonant layer as predicted by recent theoretical treatments; the optical imaging of Langmuir cavitons; the nonlinear generation of radiation bursts by collapsing cavitons; the observation of collapse in high beta plasmas in a unique quasi-steady-state magnetic plasmas. Other areas related to high power EM waves which are proposed for study are: the decay of a strong EM wave into the "2wp instabilities", the nonlinear heating and cooling rates of electrons by EM waves and the production and confinement of very high density plasmas by solely EM fields in the absence of a static magnetic field.

黄 强电磁波与磁化和非磁化等离子体相互作用中坍缩过程的研究。 该方案包括：研究电磁波在共振层产生的空泡坍缩，如最近的理论处理所预测的那样;朗缪尔空泡的光学成像;通过坍缩空泡产生的辐射爆发的非线性;在一个独特的准稳态磁性等离子体中观察高β等离子体的坍缩。 与高功率EM波相关的其他领域被提出用于研究的是：强EM波衰减为“2 wp不稳定性”，EM波对电子的非线性加热和冷却速率，以及在没有静磁场的情况下仅由EM场产生和限制非常高密度的等离子体。
