Description

The full ILL IN5B: H16 guide & chopper system + sample + PSD and tof detector, adapted for
use with Mantid-friendly NeXus output. To compile and run, use these steps:


Compile the instrument with NeXus support - zero neutrons:

export MCSTAS_CFLAGS="-g -lm -O2 -DUSE_NEXUS -lNeXus"
mcrun -c -n0 --format=NeXus ILL_H16_IN5_Mantid.instr --no-output-files

Generate the IDF in XML format using the (Perl) mcdisplay tool:

mcdisplay ILL_H16_IN5_Mantid.instr -n0 --format=Mantid

Run a simulation with NeXus output

mcrun ILL_H16_IN5_Mantid.instr --format=NeXus



The IN5@ILL TOF spectrometer from cold source to final detector, with sample.
The detector model includes Fe housing and tube cross talk absorbing masks
with angle restriction (neutrons that scatter in Fe in front of a tube and
enter a different tube are absorbed).

Input parameters

Parameters in boldface are required; the others are optional.

Name	Unit	Description	Default
lambda	AA	mean incident wavelength	4.5
dlambda	AA	wavelength half width. Use e.g. 0.8*lambda for white beam.	0.09
