The HET Instrument

HET: High Energy Transfer Chopper Spectrometer

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.


Example: mcrun HETfull.instr E_0=443.0,E_1=470.0,chop_select=450.0,nu_chop=600.0, type=2
