A new and innovative experimental research is proposed to study collisionless plasma processes in the controlled laboratory configuration. The plasma in a dipole magnetic field simulates the earth's magnetosphere. The advances in the diagnostic methods (non-intrusive) make possible reliable measurements of radial profiles of temperature and density. These are significant improvements over the old terrela-type experiments. The experimental observations are to be studied with theoretical work. Nonlinear wave interactions, hot trapped particle instability, interchange instability will theoretically be studied. The results from theory and experiment should advance understanding of basic physics and magnetospheric plasma processes.

提出了一种新的、创新的实验研究方法来研究受控实验室配置下的无碰撞等离子体过程。偶极磁场中的等离子体模拟了地球的磁层。诊断方法（非侵入式）的进步使可靠地测量温度和密度的径向分布成为可能。这些都是对旧的陆地型实验的重大改进。实验观察结果要用理论工作来研究。非线性波相互作用，热捕获粒子不稳定性，交换不稳定性将在理论上进行研究。理论和实验结果将促进对基本物理和磁层等离子体过程的理解。
