McXtrace: L_monitor Component

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

The L_monitor Component

Modified for X-ray use by Erik Knudsen Wavelength-sensitive monitor.


  • Author: Kristian Nielsen and Kim Lefmann
  • Origin: Risoe
  • Date: June 22, 2009
  • Version: $Revision$


A square single monitor that measures the wavelength of the incoming

Example: L_monitor(xmin=-0.1, xmax=0.1, ymin=-0.1, ymax=0.1,
          nL=20, filename="Output.L", Lmin=0.1, Lmax=1)

Input parameters

Parameters in boldface are required; the others are optional.
Name Unit Description Default
nL 1 Number of wavelength channels 20
filename 1 Name of file in which to store the detector image 0
xmin m Lower x bound of detector opening -0.05
xmax m Upper x bound of detector opening 0.05
ymin m Lower y bound of detector opening -0.05
ymax m Upper y bound of detector opening 0.05
xwidth m Width of detector. Overrides xmin,xmax. 0
yheight m Height of detector. Overrides ymin,ymax. 0
Lmin AA Minimum wavelength to detect  
Lmax AA Maximum wavelength to detect  
restore_xray 1 If set, the monitor does not influence the xray state 0
nowritefile 1 If set, monitor will skip writing to disk 0

Output parameters

Name Unit Description Default
L_N - Array of xray counts  
L_p - Array of xray weight counts  
L_p2 - Array of second moments
