Koizumi Lab Sekine’s (3rd year doctoral) treatise was selected as a Featured Article of AIP Advances

A paper “Measurement and identification of azimuthal current in an RF plasma thruster promoting a time-varying magnetic field” by Hokuto Sekine (3rd year doctoral student) of Koizumi Laboratory, Department of Advanced Energy Engineering, was published as a Featured Article of AIP Advances.

In the paper, we made detailed measurements on the plasma current drive when a fluctuating magnetic field is applied to the electrodeless plasma propulsion device for future space exploration.
As a result, it was shown that the electron ExB drift current as a result of the difference in the magnetization states of ions and electrons, which has not received much attention so far, is important.
Furthermore, regarding the formation of this electron ExB drift current, we proposed a hypothesis regarding the formation of a spontaneous electric field in plasma due to the “no-current boundary condition” peculiar to the electrodeless type.
We also showed that the experimental results can be well explained based on this hypothesis.
