Effect of thermal ions on fluid nonlinear frequency shift of ion acoustic waves in multi-ion species plasmas
Q. S. Feng, Q. Wang, L. H. Cao +3
A model of the fluid nonlinear frequency shift of ion acoustic waves (IAWs) in multi-ion species plasmas is presented, which considers the effect of ion temperature. Because the th…
Ion beam bunching via phase rotation in cascading laser-driven ion acceleration
H. C. Wang, S. M. Weng, M. Liu +5
The ion beam bunching in a cascaded target normal sheath acceleration is investigated by theoretical analysis and particle-in-cell simulations. It is found that a proton beam can b…
Stimulated Brillouin scattering behaviors in different species ignition hohlraum plasmas in high-temperature and high-density region
Q. S. Feng, C. Y. Zheng, Z. J. Liu +4
The presence of multiple ion species can add additional branches to the IAW dispersion relation and change the Landau damping significantly. Different IAW modes excited by stimulat…
Suppression of Stimulated Raman Scattering and Hot Electrons Generation due to Langmuir Decay Instability Cascade and Langmuir Collapse
Q. S. Feng, C. Y. Zheng, Z. J. Liu +4
Backward stimulated Raman scattering (BSRS) with Langmuir decay instability (LDI) and Langmuir collapse has been researched by Vlasov simulation for the first time. The decay produ…
Harmonics Effect on Ion-Bulk Waves in CH Plasmas
Q. S. Feng, C. Y. Zheng, Z. J. Liu +4
The harmonics effect on ion-bulk (IBk) waves has been researched by Vlasov simulation. The condition of excitation of a large-amplitude IBk waves is given to explain the phenomenon…
