## 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).

## 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"
