在D-3He聚变发电中，预计直接能量转换的应用，其中带电粒子的分离是必要的。提出了尖点型直接能量转换器（CuspDEC）作为电荷分离装置，但其性能对于高密度等离子体来说会下降。本研究的目标是建立一种利用射频 (rf) 电场的非线性效应来辅助电荷分离的附加方法。继之前的研究之后，我们通过实验研究了 CuspDEC 器件中射频场对电子运动的影响。 CuspDEC 模拟器中新安装了两个环形电极，并在射频场应用中测量了流入位于线尖点区域的电子收集器的电流。发现了电流的显着变化，并且通过适当地利用该现象可以预期电荷分离的改善。
In D-3He fusion power generation, an application of direct energy conversion is expected in which separation of charged particles is necessary. A cusp-type direct energy converter (CuspDEC) was proposed as a charge separation device, but its performance was degraded for a high density plasma. The goal of the present study is to establish an additional method to assist charge separation by using a nonlinear effect of a radio frequency (rf) electric field. Following to the previous study, we experimentally examine the effect of an rf field to electron motion in a CuspDEC device. Two ring electrodes were newly installed in a CuspDEC simulator and the current flowing into the electron collector located in the line cusp region was measured on an rf field application. The significant variation in the current was found, and an improvement of the charge separation can be expected by using the phenomenon appropriately.
