D19 - Thermal neutron single crystal diffractometer

The large structures diffractometer D19 is the monochromatic thermal neutron single crystal diffractometer of choice for determination of crystal structures with unit cells in the range of 102 to 106 Å3.
It is also unique for fibre diffraction studies of biological and industrial fibres.
