The DivPos_monitor Component

Divergence/position monitor (acceptance diagram).

Identification

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(npos=20, ndiv=20, filename="Output.dip",
          xmin=-0.1, xmax=0.1, ymin=-0.1, ymax=0.1, maxdiv=2)

Input parameters

Parameters in boldface are required; the others are optional.
Name Unit Description Default
npos 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  
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
maxdiv degrees Maximal horizontal divergence detected 2

Output parameters

Name Unit Description Default
Div_N - Array of neutron counts  
Div_p - Array of neutron weight counts  
Div_p2 - Array of second moments
