Cavitation damage on a target vessel due to proton beam-induced pressure waves is one of the crucial issues for the pulsed neutron source using a mercury spallation target. As a mitigation technique for the damage, the helium microbubble injection into the mercury has been carried out by using a swirl bubbler in order to utilize compressibility of bubbles. Moreover, double-walled structure, which consists of an outer wall and an inner wall, has been applied as the target head structure. In this study, we aim to develop an abnormality diagnostic technology to detect the inner wall cracking, which is caused by such cavitation damage, from the outside of the target vessel. The mercury flow fields in the case with the cracking are evaluated by computational fluid dynamics analysis based on finite element method. And then, effect of the cracking on the flow field is discussed from the point of view of the flow-induced vibration and the acoustic vibration.

Numerical simulation on molten metal collision behavior using SPH method combined with fractal analysis on morphology of stacking pattern

The developments of the high power proton accelerators become a worldwide interest to provide various applications, where the targets are demanded to efficiently produce secondary beams and to survive intensive MW class proton beam power supplied by the accelerators. Solid metal targets might be melted by very high heat flux that is caused by the proton beam bombardment. In fact, the incident occurred at J-PARC, in which the gold solid target was locally melted to explosively jet molten gold. The jet collided with a structural beryllium flange plate that has a function of vacuum boundary. Some parts of gold were splashed and the other stuck on the flange plate. The relationship between the impact velocity and the morphology of the sticking pattern on the plate was quantitatively evaluated by introducing fractal analysis. It was found that the fractal dimension is correlated with the impact velocity and might be a useful factor to indicate the localized impact force and behavior.

M$"o$ssbauer spectroscopy of actinide compounds

Tsutsui, Satoshi

M$"o$ssbauer Effect Reference and Data Journal, 38(4), p.105 - 111, 2015/06

M$"o$ssbauer spectroscopy of actinide compounds is limited to few facilities in the world. Study of M$"o$ssbauer spectroscopy of actinides in Japan was started in Advanced Science Research Center in the 1990s. In this paper, we summarize the research results on the M$"o$ssbauer spectroscopy of neptunium intermetallic compound that was started in the Advanced Science Research Center in 1996, and the U-238 M$"o$ssbauer spectroscopy started in the institute for Materials Research of Tohoku University. A review of the research results of the M$"o$ssbauer spectroscopy of these actinides is devoted to the late emeritus professor of Osaka University Saburo Nasu, who gives important contributions to its development.
