We study standing non-linear sausage waves in coronal loops with the plasma temperature varying with time. In our analysis we use the simplest model of a coronal loop in the form of a straight magnetic tube with a circular cross-section. We also assume that the plasma-beta is low. This enables us to neglect the magnetic ...

Comparative studies of tungsten surface damageability under irradiation with steady-state helium ion fluxes and pulsed helium ion and helium plasma fluxes in the ion-beam accelerator (ILU) and in the Vikhr Plasma Focus (PF) installation have been carried out. The parameters of irradiation with steady-state He+ ion fluxes in the ILU: helium ion energy of 30 ...

We review studies of physical processes associated with the impact of external factors in outer space — flows of micrometeoroids and solar radiation — on the lunar regolith. Under the influence of these factors, regolith microparticles can detach from the surface and levitate. Near-surface plasma and levitating dust particles form a plasma-dust exosphere of the ...

Damage to the surface layer of the Inconel 718 alloy, manufactured by selective laser melting using
additive technology followed by heat treatment, is studied under conditions of repeated pulsed exposure to
flows of helium ions and helium plasma under two irradiation modes in the Vikhr Plasma Focus installation:
in a soft mode with energy flux density q0 = ...

The effects of isothermal multidirectional forging (IMF) on the grain structure, second-phase particles of solidification origin, and dispersoids in the Al–4.9Mg–0.9Ni–0.9Fe–0.2Zr–0.1Sc alloy have been
investigated. The strain distribution over the sample volume during forging in a closed die has been analyzed
using a finite-element simulation. A method of considering the friction effect and changes in strain rate ...

The influence of pulsed helium ion (HI) and helium plasma (HP) fluxes on an Inconel 718 alloy
fabricated by an additive technology via selective laser melting and subsequent heat treatment is studied. The
structural changes in the surface layer (SL) after irradiation are analyzed for two different modes: soft (at radiation
power density q = 2 × 108 ...

We study oscillations of two parallel interacting magnetic tubes in the presence of plasma flow along the tubes. Using the cold plasma and thin tube approximations we derive the system of two equations describing these oscillations. This system of equations is valid for equilibria where the plasma density and flow velocity can vary along the ...

In this study, kinetic interaction at the Cherenkov resonance between an electromagnetic wave pulse and a flow of electrons possessing a wide velocity spread at the scale of the characteristic range of the resonant electron wave interaction is considered. Due to the absence of a distribution function slope in the range of velocities corresponding to ...

In this article we study the effect of a transitional layer in a magnetic tube on the real part
of the frequencies of kink oscillations. In our analysis, we use the model of a straight magnetic tube with the density and cross-section radius varying along the loop, and the thin-tube
thin-boundary (TTTB) approximation. First, we calculate the ...

In this article we study the plasma motion in the transitional layer of a coronal loop randomly
driven at one of its footpoints in the thin-tube and thin-boundary-layer (TTTB) approximation. We introduce the average of the square of a random function with respect to time. This
average can be considered as the square of the oscillation amplitude ...

We study kink oscillations of a straight magnetic tube in the presence of siphon flows. The
tube consists of a core and a transitional or boundary layer. The flow velocity is parallel to
the tube axis, has constant magnitude, and confined in the tube core. The plasma density
is constant in the tube core and it monotonically decreases ...
