• 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.

Name	Unit	Description	Default
nx	1	Number of pixel columns	90
ny	1	Number of pixel rows	90
filename	string	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		Numerator in k0/k weighting [AA^-1]	1
eff	1	Detector efficiency	1
restore_neutron	1	If set, the monitor does not influence the neutron state	0
nowritefile	1	If set, monitor will skip writing to disk	0
