Neutron scattering has been used for the research of magnetic materials, soft-matters, bio-matters, and engineering materials in Physics, Chemistry, Biology, and Material Science for about past 50 years.  As being emphasized further the importance of developing new materials, worldly, a lot of fund and manpower would be invested into new neutron supplying facilities and neutron scattering instruments.  Up to now, HANARO has kinds of facilities using unpolarized neutrons only. These facilities enable us to conduct experiments and researches of magnetic materials with some limits, compared with the ones utilizing polarized neutron source.  When investigating magnetic materials, it is possible to do various experiments using the polarized neutrons with outstanding advantages of the hardware of HANARO.  For the development of a polarized neutron scattering device, it is necessary to develope elementary polarized neutron technologies such as producing, retaining, and controlling the polarized neutrons.  It is, therefore, absolutly necessary to develope core technologies for the polarized neutron experimental devices which will be commissioned in HANARO afterwards.
In addition evaluation facility is also developing for detectors, monochromators, collimators and neutron mirrors because wavelength and beam divergence are easily changed.
