Description


This model describes the H512 cold guide at the ILL, with D22.

The D22 Large dynamic range small-angle diffractometer
is fully simulated. A sample can be specified (liquid),
with monitoring of the scattering in angular (diffraction) and energy modes
(for spectroscopy).


Flux given at sample positions from 
ILL_H5: D22:  nu=23589.5 [rpm] lambda=4.5 [Angs] sample=H2O_liq.qSq
Flux 1.2e8 -- 7.1e7

Input parameters

Parameters in boldface are required; the others are optional.
Name Unit Description Default
lambda Angs central wavelength band for guide illumination and D22 velocity selector setting wavelength 4.5
dlambda Angs half width of guide wavelength band .45
D22_collimation 2
D22_sample string D22 liquid/powder/amorphous sample "H2O_liq.qSq"
