Data obtained by computation for X-ray focusing using oriented Gaussian beams

Opis

The propagation of X-ray waves through an optical system consisting of several X-ray refractive lenses is considered. Gaussian beams are exact solutions of the paraxial equation. The Helmholtz equation describes the propagation of a monochromatic electromagnetic wave. Since the widths of the beams are much larger than the wavelength of X-rays, Gaussian beams can also be regarded as nearly exact solutions to the Helmholtz equation. In this approach, the propagating wave is represented as a superposition of the oriented Gaussian beams. The direction of wave propagation in each Gaussian beam is consistent with the local propagation direction of the X-ray wavefront.

 The data show the result of computation of the X-ray intensity obtained near the focal point, while X-rays are focused by 4 parabolic lenses made of beryllium. In total, the data consists of 39403 points. Each point consists of 3 numbers, which are separated by commas. The first and second numbers are responsible for the position (in millimeters) of the point on the plane, the third number - for the intensity values. Points are separated by brackets and enters.

 The  algorithm for computing the dataset is available in the paper: P. Wojda, S. Kshevetskii,  Oriented Gaussian beams for high-accuracy computation with accuracy control of X-ray propagation through a multi-lens system, J. Synchrotron Rad. (2019). 26,  363-372, https://doi.org/10.1107/S1600577518017368.
