FOUNDAMENTAL RESEARCH OF DIRECT ELECTRIC POWER GENERATOR BY USING A STRING-PLASMA

弦等离子体是一种特殊的磁化等离子体，其半径几乎等于平均离子拉莫尔半径。在这种情况下，弦等离子体中的离子引导中心被限制在等离子体柱轴线附近。由于受轴向磁场约束的电子和绕电子旋转的离子之间的电荷分离，离子被困在径向电势阱中。本文的目的是利用弦等离子体中产生的变化分离来展示直接发电装置。所得结果如下：1)通过施加在端板上的电压可以很容易地控制获得直接发电机的径向电场。2)通过改变施加在端板上的-80 - 40v电压，得到沿半径为3mm的弦等离子体轴线方向2kV/m ~ 25kv /m的径向电场。3)在此条件下，短路电流由3mA减小到1ma。4)另一方面，电子电流随着离子电流的减小而增大。电流流入端板的区域从等离子体柱的中心向外扩展。由上述结果可知，增大的径向场是由施加在端板上的正电压引起的。

A string-plasma is defined as the special one of a magnetized plasma whose redius is nearly equal to mean ion Larmor radius. In these circumstances, ion guiding centers in the string-plasma are restricted in the vicinity of the axis of the plasma column. The ions are trapped in aradial electric potential well caused by the charge separation between electrons confined by an axial magnetic field and the ions gyrating arround the electrons. It is the present purpose to show the direct electric power generator by using the chage separation caused in the string-plasma. The obtained results are as follows ;1) A radial electric field for obtaining direct electric power generator is easily controlled by the voltage applied to an end-plate.2) The radial electric fields are obtained from 2kV/m to 25 kV/m toward the axis of the string plasma having a radius of 3mm by changing the voltage applied to the end-plate of -80 -40V.3) In these conditions, the short-circuit current decrease from 3mA to 1mA.4) On the other hand, electron currents increase with decreasing ion currents. The region where the electron currents flow into the end-plate enlarge from the center to the outer region of the plasma column. From the above results, we can conclude that the increasing redial fields are obtained by the positive voltage applied to the end-plate.
