14.64 The PSD_Pol_monitor McStas Component
Position-sensitive monitor.
Identification
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")
