The DivPos_monitor Component

Divergence/position monitor (acceptance diagram).

Identification

Description

2D detector for intensity as a function of position
and divergence, either horizontally or vertically (depending on the flag vertical).
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.
