McStas: Divergence_monitor Component

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

The Divergence_monitor Component

Horizontal+vertical divergence monitor.

Identification

  • Author: Kim Lefmann
  • Origin: Risoe
  • Date: Nov. 11, 1998
  • Version: 1.23

Description

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

Example: Divergence_monitor(nh=20, nv=20, filename="Outout.pos",
          xmin=-0.1, xmax=0.1, ymin=-0.1, ymax=0.1,
          h_maxdiv=2, v_maxdiv=2)

Input parameters

Parameters in boldface are required; the others are optional.
Name Unit Description Default
nh 1 Number of pixel rows 20
nv 1 Number of pixel columns 20
filename text Name of file in which to store the detector image  
restore_neutron 1 If set, the monitor does not influence the neutron state 0
xmin m Lower x bound of detector opening 0
xmax m Upper x bound of detector opening 0
ymin m Lower y bound of detector opening 0
ymax m Upper y bound of detector opening 0
xwidth m Width/diameter of detector (x). Overrides xmin,xmax. 0
yheight m Height of detector (y). Overrides ymin,ymax. 0
h_maxdiv degrees Maximal vertical divergence detected 2
v_maxdiv degrees Maximal vertical divergence detected 2

Output parameters

Name Unit Description Default
Div_N - Array of neutron counts  
Div_p - Array of neutron weight counts  
Div_p2 - Array of second moments
