Layout of the new high intensity diffractometer for microsamples DN-6 project
Due to relatively low intensity of neutron sources the neutron scattering experiments under extreme conditions (high pressure, high and low temperature) are very complicated and they can be performed now only in a few neutron centers in the world in relatively moderate pressure range up to 10 GPa. FLNP JINR is one of such centers and realization of the new high intensity diffractometer for microsamples DN-6 project will allow to perform neutron diffraction experiments with very small samples (0.005 mm3) in much extended pressure range up to 50 GPa and higher, beyond the world achieved level. This significantly widens the research areas in the field of condensed matter physics, and complimentary fields – materials science, pharmacology, geophysics and mineralogy
