McStas: PSD_monitor_psf_eff Component

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

The PSD_monitor_psf_eff Component

Updated: Oct 15, 2007 (with psf) Position-sensitive monitor.

Identification

  • Author: Kim Lefmann, Linda Udby
  • Origin: Risoe
  • Date: Feb 3, 1998
  • Version: $Revision$

Description

An (n times m) pixel PSD monitor. This component may also be used as a beam
detector. Models 1/k behaviour and efficiency, based on user defined k0 and eff parameters.

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
nx 1 Number of pixel columns 90
ny 1 Number of pixel rows 90
filename text Name of file in which to store the detector image  
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
psf m Point spread function, ray (x,y) coordinate randomized by gaussion of sigma psf 0
k0 AA^-1 Numerator in k0/k weighting 1
eff 1 Detector efficiency 1
restore_neutron 1 If set, the monitor does not influence the neutron state 0

Output parameters

Name Unit Description Default
PSD_N - Array of neutron counts  
PSD_p - Array of neutron weight counts  
PSD_p2 - Array of second moments  
weight
