At the Japan Proton Accelerator Research Complex (J-PARC), a pulsed spallation neutron source provides neutrons with high intensity and narrow pulse width to promote researches on variety of science in Materials Life Science Experimental Facility (MLF). It was designed be driven by proton beam an energy 3 GeV, power 1 MW at repetition rate 25 Hz, that is world’s highest level. still way towards goal accomplish operation beam. In this review, distinctive features target-moderator-reflector...
The Japan Spallation Neutron Source (JSNS) at the Proton Accelerator Research Complex (J-PARC) was developed as a 1- MW spallation neutron source. A Ag-In-Cd alloy used decoupler material in two decoupled moderators. Although brings about superior neutronic performance, it has disadvantage of high residual radioactivity. Au-In- Cd been proposed solution to this problem. Recently, we successfully produced ternary Au-In-Cd alloy. composition 74.9 at% Au, 0.5 In, and 24.6 Cd. distribution...
We have been developing nanosized graphene, called graphene flower, as a material that induces coherent scattering very cold neutrons. Previous experiments found the seed part of flower is more effective than petal in increasing scattering. Based on these results, we further modification to increase portion increased total cross-section, although it did not reach level nanodiamonds.
It is proposed that nanosized graphene aggregation could facilitate coherent neutron scattering under particle size conditions similar to nanodiamonds enhance intensity below cold neutrons. Using the RIKEN accelerator-driven compact source and iMATERIA at J-PARC, we performed measurement experiments, total cross-section small-angle on aggregation. For first time, measured data revealed increased cross-sections in energy region. This most likely due scattering, resulting higher intensities,...
