The DivPos_monitor Component

Divergence/position monitor (acceptance diagram).

Identification

• Author: Kristian Nielsen
• Origin: Risoe
• Date: 1999

Description

2D detector for intensity as a function of both horizontal position
and wavelength. This gives information similar to an aceptance diagram used
eg. to investigate beam profiles in neutron guides.

Example: DivPos_monitor(nh=20, ndiv=20, filename="Output.dip",
xmin=-0.1, xmax=0.1, ymin=-0.1, ymax=0.1, maxdiv_h=2)

Input parameters

Parameters in boldface are required; the others are optional.

Name	Unit	Description	Default
nh	1	Number of bins in position	20
ndiv	1	Number of bins in divergence	20
filename	string	Name of file in which to store the detector image	0
xmin	m	Lower x bound of detector opening	-0.05
xmax	m	Upper x bound of detector opening	0.05
ymin	m	Lower y bound of detector opening	-0.05
ymax	m	Upper y bound of detector opening	0.05
xwidth	m	Width of detector. Overrides xmin,xmax.	0
yheight	m	Height of detector. Overrides ymin,ymax.	0
maxdiv_h	degrees	Maximal horizontal divergence detected	2
restore_neutron	1	If set, the monitor does not influence the neutron state	0
nx	1		0
ny	1	Vector definition of "forward" direction wrt. divergence, to be used e.g. when the monitor is rotated into the horizontal plane	0
nz	1		1
nowritefile	1	If set, monitor will skip writing to disk	0
