Optimization of compact Soller collimator
L. I. Ognev
The opportunity of optimization of collimator was investigated by changing collimator length, material and wall roughness for soft x-ray radiation with wavelength 4 nm correspondin…
Temperature bistability of charged dust particle in plasma
L. I. Ognev
By computer numerical simulation of heating of a dust conducting particle in homogeneous plasma it was shown that depending on initial temperature of a particle both heating and co…
Kinoform refraction lens with diffraction calculation
L. I. Ognev
By direct numerical simulations of the kinoform refractive lens within the quazioptical approach the effects of shape misalinement were investigated. The quazioptical approach was…
On the sensitivity of wave channeling of X-ray beam to the shape of interface channels
T. A. Bobrova, L. I. Ognev
The effect of transmission of x-ray beams through submicron capillaries was investigated with account for diffraction and roughness scattering. Possible explanation of anomalous en…
Wave channeling of X-rays in narrow rough capillaries - non Andronov-Leontovich theory
L. I. Ognev
The effect of capture of X-ray beam into narrow submicron capillary was investigated with account for diffraction and decay of coherency by roughness scattering in transitional bou…
Numerical simulation of gliding reflection of X-ray beam from rough surface
T. A. Bobrova, L. I. Ognev
A new method for investigation of x-ray propagation in a rough narrow dielectric waveguide is proposed on the basis of the numerical integration of the quazioptical equation. In ca…
