Numerical simulation of Ni-like Xe plasma dynamics and laser gain in a low inductivity capillary discharge
N. V. Kalinin, R. M. Feshchenko, I. A. Artyukov +1
X-ray lasers based on transitions in highly charged \textit{Ni}-like ions generating in the "water window" wavelength range can be pumped by compact laboratory discharge sources. T…
On inverse problem with phase retrieval for an inclined line in the parabolic approximation
R. M. Feshchenko, I. A. Artyukov, A. V. Vinogradov
The inverse problem of amplitude reconstruction on an inclined line based on the values of amplitude or its module as recorded on semi-infinite line orthogonal to the beam propagat…
Propagation of waves from an arbitrary shaped surface -- a generalization of the Fresnel diffraction integral
R M Feshchenko, A V Vinogradov, I A Artyukov
Using the method of Laplace transform the field amplitude in the paraxial approximation is found in the two-dimensional free space using initial values of the amplitude specified o…
Influence of the electron beam emittance on the polarization of a laser--electron X-ray generator
I. A. Artyukov, A. V. Vinogradov, R. M. Feshchenko
In this paper we analyze the polarization of the X-ray radiation coming from laser--electron X-ray generator (LEXG). We obtain general relations connecting the polarization state o…
