Helicon waves in a converging-diverging magnetoplasma
Félicien Filleul, Antonella Caldarelli, Kazunori Takahashi +4
Waves propagating along a converging-diverging rf magnetoplasma having the characteristics of a bounded m=0 helicon mode are reported and characterised. The discharge features a 30…
Kinetic Electron Cooling in Magnetic Nozzles: Experiments and Modeling
June Young Kim, Kyoung-Jae Chung, Kazunori Takahashi +2
As long-distance space travel requires propulsion systems with greater operational flexibility and lifetimes, there is a growing interest in electrodeless plasma thrusters that off…
Vector resolved energy fluxes and collisional energy losses in magnetic nozzle radiofrequency plasma thrusters
Kazuma Emoto, Kazunori Takahashi, Yoshinori Takao
Energy losses in a magnetic nozzle radiofrequency plasma thruster are investigated to improve the thruster efficiency, which are calculated from particle energy losses in fully kin…
Axial momentum gains of ions and electrons in magnetic nozzle acceleration
Kazuma Emoto, Kazunori Takahashi, Yoshinori Takao
The fully kinetic simulations of magnetic nozzle acceleration are conducted to investigate the axial momentum gains of ions and electrons with the electrostatic and Lorentz forces.…
Numerical investigation of internal plasma currents in a magnetic nozzle
Kazuma Emoto, Kazunori Takahashi, Yoshinori Takao
Two-dimensional fully kinetic particle-in-cell simulations of an electrodeless plasma thruster, which uses a magnetic nozzle, were conducted to investigate the thrust generation in…
Polarization reversal of electron cyclotron wave due to radial boundary condition
Kazunori Takahashi, Toshiro Kaneko, Rikizo Hatakeyama
Propagation and absorption of electromagnetic waves with electron cyclotron resonance (ECR) frequency are experimentally and theoretically investigated for the case of inhomogeneou…
