This project will utilize the large Experiment on Instabilities and Anisotropies (LEIA) device at West Virginia University to study the physics of ion temperature anisotropy driven instabilities in high beta plasmas. The primary objectives of the study will be (1) to examine the fluctuation spectra , polarizations and thresholds of the relevant instabilities, (2) provide detailed analysis of the correlation of the initial temperature anisotropy with the resulting wave characteristics, and (3) examine the role of minor heavy ion species on the waves.

该项目将利用西弗吉尼亚大学的大型不稳定性和各向异性实验装置研究高β等离子体中离子温度各向异性驱动的不稳定性的物理学。 这项研究的主要目的是：（1）检查相关不稳定性的波动谱、极化和阈值;（2）详细分析初始温度各向异性与所产生的波特征的相关性;（3）检查次要重离子种类对波的作用。
