Modulational instability of a Langmuir wave in plasmas with energetic tails of superthermal electrons
I. V. Timofeev
The impact of superthermal electrons on dispersion properties of isotropic plasmas and on the modulational instability of a monochromatic Langmuir wave is studied for the case when…
Effect of Sublevel Population Mixing on the Interpretation of Doppler-Shift Spectroscopy Measurements of Neutral Beam Content
S. Polosatkin
Interpretation of Doppler-Shift spectroscopy measurement of neutral beams species content requires an assumption about distribution of populations of thin structure of excited stat…
Electron cyclotron resonance near the axis of the gas-dynamic trap
D. S. Bagulov, I. A. Kotelnikov
Propagation of an extraordinary electromagnetic wave in the vicinity of electron cyclotron resonance surface in an open linear trap is studied analytically, taking into account inh…
Generation of powerful terahertz emission in a beam-driven strong plasma turbulence
A. V. Arzhannikov, I. V. Timofeev
Generation of terahertz electromagnetic radiation due to coalescence of upper-hybrid waves in the long-wavelength region of strong plasma turbulence driven by a high-current relati…
Effect of plasma inhomogeneity on plasma wakefield acceleration driven by long bunches
K. V. Lotov, A. Pukhov, A. Caldwell
Effects of plasma inhomogeneity on self-modulating proton bunches and accelerated electrons were studied numerically. The main effect is the change of the wakefield wavelength whic…
Natural noise and external wake field seeding in a proton-driven plasma accelerator
K. V. Lotov, G. Z. Lotova, V. I. Lotov +4
We discuss the level of natural shot noise in a proton bunch-driven plasma accelerator. The required seeding for the plasma wake field must be larger than the cumulative shot noise…
Two-dimensional simulations of nonlinear beam-plasma interaction in isotropic and magnetized plasmas
I. V. Timofeev
Nonlinear interaction of a low density electron beam with a uniform plasma is studied using two-dimensional particle-in-cell (PIC) simulations. We focus on formation of coherent ph…
Second harmonic electromagnetic emission of a turbulent magnetized plasma driven by a powerful electron beam
I. V. Timofeev
The power of second harmonic electromagnetic emission is calculated for the case when strong plasma turbulence is excited by a powerful electron beam in a magnetized plasma. It is…
