McStas: Beamstop Component

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

The Beamstop Component

Rectangular/circular beam stop.

Identification

  • Author: Kristian Nielsen
  • Origin: Risoe
  • Date: January 2000
  • Version:(Unknown)

Description

A simple rectangular or circular beam stop.
Infinitely thin and infinitely absorbing.
The beam stop is by default rectangular. You may either
specify the radius (circular shape), or the rectangular bounds.

Example: Beamstop(xmin=-0.05, xmax=0.05, ymin=-0.05, ymax=0.05)
         Beamstop(radius=0.1)

Input parameters

Parameters in boldface are required; the others are optional.
Name Unit Description Default
xmin m Lower x bound -0.05
xmax m Upper x bound 0.05
ymin m Lower y bound -0.05
ymax m Upper y bound 0.05
xwidth m Width of beamstop (x). Overrides xmin, xmax. 0
yheight m Height of beamstop (y). Overrides ymin, ymax. 0
radius m radius of the beam stop in the z=0 plane, centered at Origo 0
