McStas: Slit

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

The Slit Component

Rectangular/circular slit

Identification

  • Site:
  • Author: Erik Knudsen
  • Origin: DTU Physics
  • Date: June 16, 2009

Description

Based on Slit-comp by Kim Lefmann and Henrik Roennow
A simple rectangular or circular slit. You may either
specify the radius (circular shape), which takes precedence,
or rectangular bounds.
No transmission around the slit is allowed.



Example: Slit(xmin=-0.01, xmax=0.01, ymin=-0.01, ymax=0.01)
Slit(radius=0.01)
