The neutron instruments suite, installed at the spallation neutron source of the Materials and Life Science Experimental Facility (MLF) at the Japan Proton Accelerator Research Complex (J-PARC), is reviewed. MLF has 23 neutron beam ports and 21 instruments are in operation for user programs or are under commissioning. A unique and challenging instrumental suite in MLF has been realized via combination of a high-performance neutron source, optimized for neutron scattering, and unique instruments using cutting-edge technologies. All instruments are/will serve in world-leading investigations in a broad range of fields, from fundamental physics to industrial applications. In this review, overviews, characteristic features, and typical applications of the individual instruments are mentioned.

The instrumental design of an indirect geometry crystal analyzer spectrometer: DNA which is scheduled to be constructed in the Material and Life Science experimental Facility (MLF) at J-PARC, is reported in this article. This spectrometer is mainly aimed at searching for the high quality inelastic scattering spectra with only several mg order biomolecular sample in the plenty of wide range of energy and momentum transfers.

In the pulsed neutron source of the Material and Life Science Facility (MLF) at J-PARC, we are planning and partially beginning the construction of the near backscattering Si crystal analyzer spectrometer DNA. 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.

We are planning and partially beginning the construction of the near backscattering Si crystal analyzer spectrometer DNA at the Material and Life Science Facility (MLF), J-PARC. The optical specification of DNA is as follows. In the center of the vacuum chamber, a sample position is located at 42 m away form the coupled moderator. The analyzer banks of Si(111) and Si(311) single crystal wafers which are pasted on the spherical surface, are mounted at the right and left side each in the vacuum chamber. The Bragg angle of those analyzer crystals are about 87.5 deg and the distance between the sample position and the analyzer crystal is about 2.3 m. The analyzed neutron beams are detected by the Hee gas position sensitive detector located at around the sample position. Then the expected energy resolution and the dynamic range of the Si(111) crystal analyzer are about 1 micro-eV and 40 micro-eV, respectively. We will report the optical principle and specification of DNA spectrometer.

A Si-crystal analyzer backscattering spectrometer DNA is planned to be installed at the pulsed neutron source of the Material and Life Science Facility (MLF), J-PARC, and the construction has partially begun in the summer of 2010. 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.
