D1B (CRG) - High intensity two-axis powder diffractometer

D1B is a high intensity powder diffractometer with a PSD covering the angular range 0.8 to 128.8º. Highly demand for real time experiments, and for very small samples because of its high efficiency position sensitive detector (PSD). It runs as a CRG-A instrument by CNRS / CSIC. 50% of beam time is used by ILL experiments while the other 50% of the beam time is used by CNRS and CSIC.
