Directions for development of spectrometers complex First priority projects – creation of new high intensity diffractometer for microsamples DN-6, new multifunctional reflectometer GRAINS, upgrade of SKAT/EPSILON spectrometers complex (with external funding from BMBF) 2. Second priority projects – completion of the FSD diffractometer project, upgrade of the spectrometers HRFD, DN-2, YuMO, REMUR, REFLEX, NERA-PR, DIN-2PI 3. Development of the projects of new small angle neutron scattering spectrometer and neutron reflectometer with atomic resolution 4 Development of new neutron scattering methods for studies of structure and dynamics of nanosystems and novel materials 1 м 32 м 8 м Background chopper Neutron guide Detector system 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
