McStas: PSD_Pol_monitor

[ Identification | Description | Input parameters | Links ]

The PSD_Pol_monitor Component

Position-sensitive monitor.

Identification

  • Site:
  • Author: Alexander Backs, based on PSD_monitor by K. Lefmann
  • Origin: ESS
  • Date: 2022

Description

An (n times m) pixel PSD monitor, measuring local polarisation as function of x,y coordinates.

Example: PSD_Pol_monitor(xmin=-0.1, xmax=0.1, ymin=-0.1, ymax=0.1, nx=90, ny=90, my=1, filename="Output.psd")

Input parameters

Parameters in boldface are required; the others are optional.
