[MTT48-P10] Non-destructive elemental analysis of a carbonaceous chondrite with direct current Muon beam at MuSIC
キーワード：ミューオン、非破壊元素分析、はやぶさ2
Electron- or X-ray-induced characteristic X-ray analysis has been widely used to determine chemical
compositions of materials in vast research fields. In recent years, analysis of characteristic X-rays from
muonic atoms, in which a muon is captured, has attracted attention because both a muon beam and
a muon-induced characteristic X-ray have high transmission abilities. Here we report the first nondestructive elemental analysis of a carbonaceous chondrite using one of the world-leading intense direct current muon beam source (MuSIC; MUon Science Innovative Channel). We successfully detected
characteristic muonic X-rays of Mg, Si, Fe, O, S and C from Cl chondrite, of which carbon content is about 3 wt%. Because of its high sensitivity to carbon, non-destructive elemental analysis with a muon beam can be a novel powerful tool to characterize future retuned samples from carbonaceous asteroids.
