The ILL_H5 Instrument

The full H5 cold guide at the ILL, with IN14, D16, Super-Adam, IN15, D22 This is the geometry before the major H5 guide hall upgrade (up to 2013).

Identification

Description

This model decribes the full H5 cold guide at the ILL, with IN14, IN16, D16,
Super-Adam, IN15, D22.

The IN14 Cold neutron three-axis spectrometer IN14
The IN16 Cold neutron backscattering spectrometer IN16
simulated down to the 2nd deflector, and does not include the full
backscattering geometry.
The D16 Small momentum transfer diffractometer D16 is realistic
The SuperADAM reflectometer is used in low angle diffraction mode.
The IN15 Spin-echo spectrometer
is simulated with an incoming polarized beam, but not with a full spin-echo
description.
The D22 Large dynamic range small-angle diffractometer
is fully simulated
The CryoEDM with its polarized beam

For each instrument, a sample can be specified (liquid/powder/amorphous),
with monitoring of the scattering in angular (diffraction) and energy modes
(for spectroscopy).
