During 50 years, I have engaged in the neutron diffraction experiments. We constructed many machines, and produced many researches mainly in the field of magnetism. At the early stage we started our experiment at the old JRR-3 reactor of low neutron flux density. Now, we are using renewed JRR-3 of high flux with low noise. But the reactor is not operated since the disaster 3.11 in 2011. We are eager for JRR-3 to restart.
