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.

拟议的研究涉及对快速太阳风加速区域中离子加热的实验室研究。 已经提出了许多用于在快速太阳风中加热离子加热的机制，该项目将研究一种可能性，即相反的，低频，alfven波会产生一个动荡的级联反应，从而使离子上的较高的频率波在离子上潮湿，或者使离子在离子上受到潮湿的潮湿，或者由离子 - cyclotron sage cyclotron降温。
