McStas: PSD_monitor_psf_eff

[ Identification | Description | Input parameters | Links ]

The PSD_monitor_psf_eff Component

Position-sensitive monitor.

Identification

  • Site:
  • Author: Kim Lefmann, Linda Udby
  • Origin: Risoe
  • Date: Feb 3, 1998

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.
