Outline of Final Research Achievements

In this research, radio frequency (rf) electric field is used for improvement of charge separation performance of a cusp-type direct energy converter employed in fusion direct power generation.
The first experiment using a mesh electrode in front of the ion collector revealed effectiveness of rf field parallel to the magnetic field. According to this result, a pair of ring electrodes were settled in front of the electron collector. The experiment using the ring electrodes showed increase of electron current in a certain condition. To examine the physical mechanism of the phenomena, electron orbits were calculated. The calculation results suggested the difference of running time of electrons might correspond to the experimental results.
The physical mechanism has not been necessarily clarified yet, but a possibility to improve the device performance is shown. The research will be continued in order to apply the phenomena to the practical device.
