McStas: Divergence_monitor

[ Identification | Description | Input parameters | Links ]

The Divergence_monitor Component

Horizontal+vertical divergence monitor.

Identification

  • Site:
  • Author: Kim Lefmann
  • Origin: Risoe
  • Date: Nov. 11, 1998

Description

A divergence sensitive monitor. The counts are distributed in
(n times m) pixels.

Example: Divergence_monitor(nh=20, nv=20, filename="Output.pos",
xmin=-0.1, xmax=0.1, ymin=-0.1, ymax=0.1,
maxdiv_h=2, maxdiv_v=2)

Input parameters

Parameters in boldface are required; the others are optional.
