We are beginning the construction of the near backscattering Si crystal analyzer spectrometer DNA in the pulsed neutron source of the Material and Life Science Facility (MLF) at J-PARC. This is the spectrometer to cover the area of the micro-eV energy range in the several spectrometers which are in the construction or planned the construction in MLF. The field of expected scientific research on the DNA spectrometer is very wide including the soft matter dynamics, the bio-molecular dynamics, the chemical molecular dynamics, the characterizations of the functional materials and the spin dynamics in the magnetism. We will report the present status of the construction schedule on DNA.
