McXtrace: PSD_monitor Component

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

The PSD_monitor Component

Position-sensitive monitor.


  • Author: Erik B Knudsen
  • Origin: Risoe
  • Date: June 22, 2009
  • Version: $Revision$


Based on neutron component written by Kim Lefmann
An (nx times ny) pixel PSD monitor. This component may also be used as a beam
detector. If instead of xwidth, yheight a radius is given, the component has a circular footprint
and integrates circularly (caking).

Example: PSD_monitor(xmin=-0.1, xmax=0.1, ymin=-0.1, ymax=0.1,
            nx=90, ny=90, filename="Output.psd")

Input parameters

Parameters in boldface are required; the others are optional.
Name Unit Description Default
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
radius m Radius of circular detetor. 0
restore_xray 1 If set, the monitor does not influence the xray state. 1
nowritefile 1 If set, monitor will skip writing to disk 0
nx 1 Number of pixel columns. 90
ny 1 Number of pixel rows. 90
nr 1 Number of radial pixels. 0
