Thermal neutron three-axis spectrometer with polarization analysis IN20
IN20 - Thermal neutron three-axis spectrometer with polarisation analysis
IN20 is a thermal beam three-axis spectrometer for inelastic scattering experiments in various sample environments (eg. magnets up to 15 T). It can be equipped with single-analyser-detector or Flatcone (an inclinable multianalyser-detector to study energy cuts in, above and below the central reciprocal scattering plane), with standard Helmholtz or CRYOPAD (zero-field) polarisation analysis, polarisation analysis in horizontal magnetic fields or vertical magnetic fields.
IN20 has received new monochromator and analyser optics for improved flux and instrument flexibility. A velocity selector suppresses higher-order wavelengths from the monochromator enabling increased flexibility and improved signal-to-noise.
