McStas: ILL_H142_D33

[ Identification | Description | Input parameters | Links ]

The ILL_H142_D33 Instrument

A simplified H142 cold guide model at the ILL, with a simple D33 model at the end

This model decribes a simiplified H142 cold guide at the ILL, with D33.

The D33 Massive dynamic q-range small-angle diffractometer is a Small-Angle Neutron
Scattering instrument for the characterization of samples with typical sizes
varying from the nanometer scale to few tenth of micrometer. In addition to a
standard monochromatic mode of operation, D33 offers a time of flight mode (TOF)
to cover an enhanced dynamic q-range qmax/qmin in one instrument setting. High
magnetic fields, up to 17 T at the sample position, beam polarization and 3He
spin analysis, facilitate and expand studies of magnetism and allow a more
quantitative analysis of spin incoherent samples. The high flux allows for
kinetic experiments with time resolution of the order of few milliseconds.
