The ILL_IN5 Instrument



The IN5@ILL TOF spectrometer from chopper system 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). This model does not include the H16 guide.

Example: lambda=4.5 Detector: Det_PSD_I=1.3e6
