D2B - High-resolution two-axis diffractometer

D2B is very high-resolution powder diffractometer designed to achieve the ultimate resolution, limited only by powder particle size (Δd/d 5x10-4), but is was built so that an alternative high flux option, with resolution comparable to that of D1A, but much higher intensity, could be chosen at the touch of a button.


  • The structural chemistry of non-rigid molecules
  • Ab-initio structure solution from powders
  • Crystal and magnetic structure determination of powder compounds (even small samples)
  • Dependance in temperature/pressure/magnetic field structural (or magnetic) studies for powders
