HYPER-II装置是在九州大学建造的，用于研究离子非磁化等离子体中的流动结构形成，离子非磁化等离子体是等离子体的中间状态，由非磁化离子和磁化电子组成。利用电子回旋共振加热产生高密度等离子体，并利用定向朗缪尔探针法和激光诱导荧光法研究了非均匀磁场中的流场结构。实验装置已经完成，诊断系统已经安装，开始实验。通过引入一组同轴电极来控制等离子体的方位旋转，研究了等离子体旋转对产生直线流结构的影响。HYPER-II实验将阐明非均匀磁场中的整体流动结构，有助于理解等离子体中间态的特征。
The HYPER-II device has been constructed in Kyushu University to investigate the flow structure formation in an ion-unmagnetized plasma, which is an intermediate state of plasma and consists of unmagnetized ions and magnetized electrons. High density plasmas are produced by electron cyclotron resonance heating, and the flow field structure in an inhomogeneous magnetic field is investigated with a directional Langmuir probe method and a laser-induced fluorescence method. The experimental setup has been completed and the diagnostic systems have been installed to start the experiments. A set of coaxial electrodes will be introduced to control the azimuthal plasma rotation, and the effect of plasma rotation to generation of rectilinear flow structure will be studied. The HYPER-II experiments will clarify the overall flow structure in the inhomogeneous magnetic field and contribute to understanding characteristic feature of the intermediate state of plasma.
