Because of its high spatial resolution and the high flux at lambda 2.52Å, D1B is one of the most powerful powder diffractometer for magnetic structures studies. In addition to its multidetector, surface studied such as adsorbed phases as well as real-time diffraction experiments are possible.

Collecting a diffraction pattern with sufficient statistics in minutes (1 ~ 5 mn) even seconds allows in situ studies of reaction kinetics. A fast detection of phase transitions can also be obtained by scanning the temperature. A complete thermal variation of the diffraction patterns (1.5K-300K) can be achieved in few hours (3 ~ 5 h).

The texture of polycrystals can also be investigated using the Eulerian cradle available on D1B. Scanning in phi and chi at 2 or 3 omega positions allows the complete determination of the pole figures in typically one day for one sample.
