Identification

- Author: Erik B Knudsen
- Origin: DTU Physics
- Date: Jun. 16
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. Based on neutron component by Kim Lefmann 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)
