McStas: ISIS_HET

[ Identification | Description | Input parameters | Links ]

The ISIS_HET Instrument

Identification

Description

This instrument is a simple model of the HET spectrometer at the ISIS neutron
facility. The input arguments are hardwired so that the Fermi chopper position
is 10 metres from the moderator. This instrument uses the FC module written by
Andrew Garret which comes with no guarantees as to its accuracy in modelling the
Fermi Chopper.

Input parameters

Parameters in boldface are required; the others are optional.
