D1B (CRG) - High resolution neutron two-axis powder diffractometer

The D1B-CRG is a high intensity powder diffractometer with an 128° PSD. It has always been in very high demand for real time experiments, and for very small samples because of its high efficiency position sensitive detector (PSD). Run as a CRG-A instrument by a CNRS / CSIC team, it is available 50% of the time for scheduled ILL experiments.

D1B - High resolution neutron two-axis powder diffractometer

D1B is a high intensity powder diffractometer with a new steady 128° PSD covering the angular range 0.8 to 128.8º. It has always been in very high demand for real time experiments, and for very small samples because of its high efficiency position sensitive detector (PSD). The new PSD makes it an even more valuable tool. Run as a CRG-A instrument by a CNRS / CSIC team, it is available 50% of the time for scheduled ILL experiments.

Applications

  • Determination of magnetic structure
  • Study of spin reorientation transitions
  • Phase transitions investigated by thermodiffractometry
  • Time resolved experiments kinetics studies
  • Dynamical studies in solid state chemistry
  • In situ neutron diffraction
  • In situ chemistry, chemical intercalation via solid-gas reaction
  • Texture analysis
  • Physisorption
