Scattering power of neutron against proton remarkably depends on relative direction of these spins. Spin contrast variation (SCV) is a technique to determine structure of composite materials from their polarized neutron scattering profiles that vary as a function of proton polarization. Very recently, we succeeded in the first SCV neutron reflectometry measurement. We determined roughness of two surfaces of a thin-film polymer from the SCV neutron reflection curves. We will use this technique to study structures of multilayered films such as coupling agents (glues) between organic and inorganic materials.

The instrument control software framework "IROHA2" have been introduced and used in several neutron instruments at MLF, J-PARC. IROHA2 consists of several severs, which are the device control, the instrument management, the sequence management and the integrate control. Users cooperate to use these servers to carry out their experiments with a web browser. By the development since last year, new features are implemented to IROHA2 as follows: (1) Real-time data processing interface on the device control server with a distributed messaging middleware, (2) Flexible web user interfaces for automatic measurements on the sequence management server, (3) Remote experimental status monitoring system on the integrate control server, which is access controlled by the MLF integrate authorization system. We will report the implementation status and future plans of IROHA2.

It is necessary for the understanding of structure polymorphism of various molecules and interacting protein and the plastic molecules base to clarify the fluctuation of the domain as the mer. In this study, I targeted protein MurD consisting of three domains and a ligand was in a free state and analyzed domain exercise by the quantum beam dispersion method using X-rays and the neutron and the correlation structure analytical method that fused of the molecules simulation about an ATP-binding state, three states of the Compound1-binding state. By the solution small angle scattering experiment, I showed that the solution structure of the 3 state was different. In addition, I showed good agreement with the dispersion profile obtained from the molecular simulation and confirmed that I could discuss solution structure in atom resolving power from experimental data of the low resolving power. I extracted a domain campaign in conjunction with the function from the chief ingredient analysis of the molecular simulation result. Furthermore, a result to suggest what a fluctuation and a couple of the amino acid residue that this domain campaign participated in the combination with interaction molecules of MurD did was provided. By the method that fused by an experiment method of dynamic solution structure analysis including a neutron spin echo and technique of the calculation science in addition to small angle scattering, I visualize domain exercise of protein in atom resolving power and, in the announcement, argue by a function of the protein from the dynamic structure that a couple did between the hierarchies of different space scale.

Sample environment (SE) team is organized at the MLF of the J-PARC. SE equipment are prepared and the users are supported by the SE team. SE team consists of sub-team of (1) low temperature & magnetic field, (2) high temperature, (3) high pressure, (4) soft matter, (5) pulsed magnet, (6) light irradiation, (7) 
He spin filter. In this presentation, we will present the current status of the sample environmental equipment, the future plan and the support activities for users.

The magnetic structure of CsCuMoO has been studied by using the neutron powder diffraction. Cu
spins collinearly ordinate along the 
axis and we found that this material has ferromagnetic structure in ribbon chains and antiferromagnetic structure between ribbon chains. Those results indicate that the magnetic structure is strongly inflected with ferromagnetic . In this presentation, the detail of magnetic structure of this material will be discussed.

The crystal and magnetic structures of BaCoCaRuO has been studied by using the neutron powder diffraction. We also carried out the measurements of magnetic properties of this sample. 
is decreased with increasing the fraction of Ca ion, and we found that is 76 K at the fraction of Ca = 0.3. although the lattice constants of the sample are increased by the substituting Ca for Co ion, a Ru-Ru bond length decreases with increasing fraction of Ca ion. In this presentation, the details of the magnetic properties and magnetic structure of this material will be discussed.

The time-of-flight (TOF) type near-backscattering spectrometer (n-BSS), DNA, with Si crystal analyzers was built and started operation in 2012 at the Materials and Life Science Experimental Facility (MLF) of the Japan Proton Accelerator Research Complex (J-PARC). DNA is the first n-BSS with pulse shaping chopper installed at a spallation pulsed neutron source.

Utsusemi is the software to analyze and visualize data measured by the neutron scattering experiments at MLF in J-PARC. Utsusemi has achieved to treat the data obtained by the event-recording method, which MLF had adopted as a standard data acquisition system, and to realize the multi-Ei method on the inelastic scattering measurement for the first time in the world. On the other hand, users in MLF require to see the analyzed data while measuring to decide next experimental schedules. We, therefore, had started to develop the software to obtain the information, analysis and visualization of measured data in real time since last year. We report the current status for these developments.
