Wall Ion Loss Reduction by Acceleration Zone Shifting in Anode-Layer Hall Thruster
Rei Kawashima, Yushi Hamada, Shu Kawabata +2
In this study, wall ion loss and erosion rate are evaluated in the RAIJIN thruster. The novelty of this work is the detailed analysis of measured guard-ring (metallic channel wall)…
Two-dimensional hybrid model of gradient drift instability and enhanced electron transport in a Hall thruster
Rei Kawashima, Kimiya Komurasaki
An axial-azimuthal two-dimensional Hall thruster discharge model was developed for analyzing gradient drift instability (GDI) and cross-field electron transport enhancement induced…
Optical emission spectroscopy of non-equilibrium microwave plasma torch sustained by focused radiation of gyrotron at 24 GHz
Sergey Sintsov, Kuniyoshi Tabata, Dmitry Mansfeld +2
The electron and gas temperature of non-equilibrium argon plasma torch sustained by a focused 24 GHz microwave beam in the external atmosphere of air was measured by optical emissi…
Two-dimensional Modeling of the Hall Thruster Discharge with Non-uniform Propellant Supply in Azimuth
Rei Kawashima, Junhwi Bak, Kimiya Komurasaki +1
A two-dimensional simulation is conducted to investigate the effect of cross-field electron transport enhancement in the Hall thruster discharge caused by the nonuniform propellant…
Numerical analysis of azimuthal rotating spokes in a crossed-field discharge plasma
R. Kawashima, K. Hara, K. Komurasaki
Low-frequency rotating spokes are obtained in a cross-field discharge plasma using two-dimensional numerical simulations. A particle-fluid hybrid model is used to model the plasma…
