Thermal neutron three-axis spectrometer
IN22 is a CRG instrument operated at the ILL by the CEA-Grenoble DRFMC/SPSMS. It is a thermal neutron three-axis spectrometer especially designed for inelastic neutron scattering under high magnetic fields. It is equipped for both longitudinal and spherical polarisation analysis. The machine is optimized to work with neutrons of incident energies in the range between 5 and 100 meV, thanks to H25 a m=2 supermirror guide.
Here the instrument is shown in its classical setting for magnetic studies. The neutron beam is polarised and the sample is placed in the high magnetic field of a cryomagnet.
