McXtrace: Lens_parab_Cyl

[ Identification | Description | Input parameters | Output parameters | Links ]

The Lens_parab_Cyl Component

Cylindrical (1D) CRL stack

Identification

  • Site:
  • Author: Jana Baltser and Erik Knudsen
  • Origin: NBI
  • Date: April 2011

Description

.
An X-ray compound refractive lens (CRL) with a parabolic cylinder profile focusing in 1D, i.e. onto a line

The lens is invariant along the x-axis and has a parabolic profile along the y-axis defined as z/c = y^2/b^2.
Thus, i.e. it focuses onto a line along the x-axis.
N>1 means that a stack of lenses is to be simulated. Each lens consists of a pair of two opposing parabolic surfaces
with a distance d between them. The reference point of the component is at the bottom of the first parabolic
surface.
