Research Abstract

The purpose in this study is the development of the practical protection technologies for mitigating the pressure waves by the microbubble injection in the liquid mercury spallation neutron source. We investigated the mitigation technologies from the viewpoints of microbubble injection, pressure wave propagation in bubbly liquid, bubble-bubble interaction, and pitting damage. As results, we developed the technique to mitigate the cavitation damage, which becomes barrier to realize the MW-class spallation target.
