Development of new machine for experimentally testing extended MHD models by merging positive nonneutral plasma with negative nonneutral one

在这项研究中，一个新的机器实验测试扩展的MHD模型的开发。这台机器是基于著名的潘宁陷阱。但是，在机器的真空室中，产生正和负电位威尔斯。在这些势威尔斯的底部，锂离子和纯电子等离子体都被成功地捕获。值得注意的是，这些非中性等离子体不仅是独立产生的，而且是同时被限制的。利用所研制的实验装置，我们可以进行扩展磁流体等离子体的实验。

In this study, a new machine for experimentally testing the extended MHD models is developed. This machine is based on the well-known penning trap. But, in the vacuum chamber of the machine, both positive and negative potential wells are created. At bottoms of those potential wells, both lithium ion and pure electron plasmas are successfully trapped. Noteworthy, those non-neutral plasmas have been not only produced independently but also confined simultaneously. With the developed machine, we are ready for performing the experiment on the extended MHD plasmas.
