About this blogDiffraction is a technique to determine the atomic structure of materials very accurately. Most scientists use X-ray diffraction (XRD) for this, but hydrogen and neighbours in the periodic table of Mendeleev are sometimes hard to find or distinguish. Neutron diffraction can do precisely that! Moreover, magnetic structures can be revealed and atoms can be highlighted or masked by isotope substitution.
Since neutrons are difficult to generate, such a diffractometer is not avaible within 500km, so the Reactor Institute Delft (TU Delft) has taken up the initiative to provide such an instrument to Dutch users.
This blog is about the progress of the design and building of PEARL: the Dutch neutron (powder) diffractometer.
