ILL_IN5_Spots InstrumentThe 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
