Stabilization of the mode in a long-thin mirror trap with high-beta anisotropic plasmas
Igor Kotelnikov, Vadim Prikhodko, Dmitri Yakovlev
The stabilization of ``rigid'' flute and ballooning modes in an axisymmetric mirror trap with the help of an ideally conducting lateral both in the presence and in the abse…
Wall stabilization of the rigid ballooning mode in a long-thin mirror trap
Igor Kotelnikov, Vadim Prikhodko, Dmitri Yakovlev +4
The prospect of stabilization of the ``rigid'' ballooning mode in an open axially symmetric long-thin trap with the help of a conducting lateral wall surrounding a column of…
On the stability of small-scale ballooning modes in mirror traps
Igor Kotelnikov, Qiusun Zeng
It is shown that steepening of the radial plasma pressure profile leads to a decrease in the critical value of beta, above which small-scale balloon-type perturbations in a mirror…
On the structure of the boundary layer in a Beklemishev diamagnetic bubble
Igor Kotelnikov
The article provides a kinetic description of the plasma equilibrium in the Beklemishev diamagnetic trap, where the traditional approach based on the theory of magnetic drifts is n…
Diffraction of Bessel beams on 2D amplitude gratings -- a new branch in the Talbot effect study
I. A. Kotelnikov, O. E. Kameshkov, B. A. Knyazev
In this paper, an analytical theory for the diffraction of a Bessel beam of arbitrary order on a 2D amplitude grating is presented. The diffraction pattern in the main an…
Electron radiative recombination with a hydrogen-like ion
Igor A. Kotelnikov, Alexander I. Milstein
We survey the results of a long-term study of the process of radiative recombination. A rigorous theory of nonrelativistic electron radiative recombination with a hydrogen-like ion…
Dispersion Relation of a Surface Wave at a Rough Metal-Air Interface
Igor Kotelnikov, Gennady Stupakov
We derived a dispersion relation of a surface wave at a rough metal-air interface. In contrast to previous publications, we assumed that an intrinsic surface impedance due to a fin…
Photon trap for neutralization of negative ion beams
S. S. Popov, A. V. Burdakov, A. A. Ivanov +1
For effectively neutralization of the powerful negative ions beams of hydrogen and deuterium the photon target is considered in long time. The attractiveness of the traditional app…
Solution of the Pierce problem near a corner of a rectilinear flow with a polygonal cross-section
Igor A. Kotelnikov
An ill-posed problem of synthesis of the Pierce electrodes for a cylindrical beam with a polygonal cross-section is considered. It is assumed that a beam of charged particles is ex…
On the density limit in the helicon plasma sources
Igor A. Kotelnikov
Existence of the density limit in the helicon plasma sources is critically revisited. The low- and high-frequency regimes of a helicon plasma source operation are distinguished. In…
Electromagnetic surface waves on a conducting cylinder
I. A. Kotelnikov, G. V. Stupakov
We study propagation of electromagnetic surface waves on a metal-air interface in the case when the wave frequency is below the plasma frequency. We derive a reduced wave equation…
Diffraction of surface wave on conducting rectangular wedge
Igor A. Kotelnikov, Vasily V. Gerasimov, Boris A. Knyazev
Diffraction of a surface wave on a rectangular wedge with impedance faces is studied using the Sommerfeld-Malyuzhinets technique. An analog of Landau's bypass rule in the theory of…
