On collisions driven negative energy waves and Weibel instability of a relativistic electron beam in a quasi-neutral plasma
Anupam Karmakar, Naveen Kumar, Gennady Shvets +2
A new quasi-neutral model describing the Weibel instability of a high-current relativistic beam propagating through a resistive plasma is developed. It treats beam electrons as kin…
Three dimensional filamentary structures of a relativistic electron beam in Fast Ignition plasmas
Anupam Karmakar, Naveen Kumar, Oleg Polomarov +2
The filamentary structures and associated electromagnetic fields of a relativistic electron beam have been studied by three dimensional particle-in-cell (PIC) simulations in the co…
Revisiting the anomalous rf field penetration into a warm plasma
Igor D. Kaganovich, Oleg V. Polomarov, Constantine E. Theodosiou
Radio frequency waves do not penetrate into a plasma and are damped within it. The electric field of the wave and plasma current are concentrated near the plasma boundary in a skin…
Influence of ambipolar potential on the properties of inductively coupled discharges at the bounce resonance condition
Oleg V. Polomarov, Constantine E. Theodosiou, Igor D. Kaganovich
The importance of accounting for an ambipolar electrostatic potential or a non-uniform density profile for modelling of inductively coupled discharges is demonstrated. A drastic en…
Self-consistent system of equations for a kinetic description of the low-pressure discharges accounting for the nonlocal and collisionless electron dynamics
Igor D. Kaganovich
For low-pressure discharges, when the electron mean free path is larger or comparable with the discharge length, the electron dynamics is essentially nonlocal. Moreover, the electr…
