Maximizing Ion Current by Space Charge Neutralization using Negative Ions and Dust Particles

Abstract

Ion current extracted from an ion source (ion thruster) can be increased above the Child-

Corona based air-flow using parallel discharge electrodes

“…It is also distinguished from, for example, a our experimental work as well as numerical simulation showed that due to the modified configuration, the ion movement is controlled to be parallel with the axes of the electrodes and away from the device. Because of the high recombination rate of ions 20 , the net charge released is very low. Due to easy scalability and low net charge, the present configuration is beneficial to applications with space constraints and/or where neutralized discharge process is required, such as inertial fluidic units 21 , circulatory flow heat transfer 22 , electrospun polymer nanofiber to overcome the intrinsically instability of the process 23 , or the formation of low charged aerosol 24 .…”
