Current Status and Future Prospect of Neutron Facilities at China Advanced Research Reactor

Neutron research facilities have been built on the high flux neutron source China Advanced Research Reactor(CARR), of which different kinds of neutron techniques, including neutron scattering, neutron imaging and neutron activation analysis, are now available. The neutron scattering instruments, including neutron diffractometers, small-angle neutron scattering, neutron reflectometer, inelastic neutron scattering spectrometers, can be used to analyze the microstructure and dynamic properties of materials. The thermal neutron imaging and cold neutron imaging facilities can be used for the non-destructive testing of defects inside materials. And neutron activation analysis systems are powerful for the detection of different elements or isotopes. There are now 19 neutron instruments which have been built or under construction. Some sample environment devices are also available. These facilities provide important support for both fundamental scientific researches and industrial applications in the fields of physics, chemistry, material science, life science, energy, environment and so on. CARR neutron research facilities will continue to open to the users from outside the institute, to not only serve scientific frontier researches, but also meet the major national innovation needs.
