D20 - High-intensity two-axis diffractometer with variable resolution

D20 is very high intensity 2-axis diffractometer equipped with a large microstrip detector. Due to the extremely high neutron flux, it opens up new possibilities for real-time experiments on very small samples.

Applications

  • Thermodiffractometry; Magnetism; Kinetics; Multi-stroboscopy; Texture; Very small samples; Highly absorbing samples; Disordered systems; Physisorption

 

 

Instrument layout

The complete diffraction pattern at 1536 positions, covering a scattering range of 153.6°, can be obtained in a matter of seconds, and followed as a function of temperature, pressure or other parameter. The variable monochromator take-off angle, up to 120°, increases the flexibility of the instrument, providing high resolution over the complete diffraction pattern at the highest take-off angle with a neutron flux of up to 107ns-1cm-2 or a high flux of up to 108ns-1cm-2 at medium resolution at lower take-off angle.
