Influence of dust particles on ionization equilibrium in partially ionized plasmas

Fri, 06/05/2020 - 10:00

Author(s): A. E. Davletov, F. Kurbanov, and Ye. S. Mukhametkarimov

A chemical model is proposed for a dusty plasma consisting of electrons, ions, neutrals, and positively charged dust particles all being at thermodynamic equilibrium. An expression is derived for the Helmholtz free energy, which comprises the ideal part, taking into account the charge of dust partic...

Turbulence model reduction by deep learning

Thu, 06/04/2020 - 10:00

Author(s): R. A. Heinonen and P. H. Diamond

A central problem of turbulence theory is to produce a predictive model for turbulent fluxes. These have profound implications for virtually all aspects of the turbulence dynamics. In magnetic confinement devices, drift-wave turbulence produces anomalous fluxes via cross-correlations between fluctua...

Author(s): B. Z. Chen, D. Wu, J. R. Ren, D. H. H. Hoffmann, and Y. T. Zhao

Transport of particle beams in plasmas is widely employed in fundamental research, industry, and medicine. Due to the high inertia of ion beams, their transport in plasmas is usually assumed to be stable. Here we report the focusing and flapping of intense slab proton beams transporting through larg...

Author(s): Sam Yaghoubi, Abbas Ghasemizad, and Soheil Khoshbinfar

Compressing and charge neutralization of the heavy-ion beam in an inertial fusion reactor are considered as pivotal processes for increasing the energy gain. For this purpose, the ion beam is usually transported through the plasma channel so that multispecies Weibel instability can grow in this syst...
