The proposed reseach concerns a laboratory investigation of ion heating in the acceleration region of the fast solar wind. A number of mechanisms for ion heating in the fast solar wind have been proposed and this project will examine the possibility that either counter-propagating, low-frequency, Alfven waves generate a turbulent cascade that heats ions by exciting higher frequency waves that damp on the ions or that the ions are directly heated by ion-cyclotron damping of Alfven waves.

这项拟议的研究涉及快速太阳风加速区离子加热的实验室研究。人们已经提出了在快速太阳风中加热离子的许多机制，该项目将研究这样一种可能性：要么是反向传播的低频阿尔芬波产生湍流级联，通过激发抑制离子的高频波来加热离子，要么是阿尔芬波的离子回旋衰减直接加热离子。
