9413046 Bellan This proposal calls for an investigation of the linkage between orbit stochasticity, a microscopic effect, and macroscopic properties of the plasma. In particular the investigator will look for a flattening of the distribution function and a reduction of fluid response to the drift wave in the plasma. The technique used will involve laser induced fluorescence. In a more sophisticated application of the fluorescence technique, optical tagging will be used to allow tracking the trajectories of specific subgroups of ions.

9413046贝兰这项建议要求调查轨道随机性、微观效应和等离子体宏观性质之间的联系。特别是，研究人员将寻找分布函数的平坦化和减少对等离子体中漂移波的流体响应。所使用的技术将涉及激光诱导荧光。在荧光技术的一个更复杂的应用中，将使用光学标记来跟踪特定离子亚群的轨迹。
