物質にミュオンを捕捉させたのちに放出される高いエネルギーのミュオン特性X線を用いた物質内部の非破壊元素分析法の開発が行われている。我々は天文学に使われている二次元テルル化カドミウム硬X線検出器(CdTe-DSD)を活用し、ミュオンビームによる非破壊三次元元素イメージング手法を確立した。

Non-destructive elemental analysis method by muon characteristics X-ray (muonic X-rays) measurement using a negative muon beam is useful in the fields of archaeological artifacts and extraterrestrial materials. Using two-dimensional imaging detector, this method can be expanded to non-destructive three-dimensional elemental analysis. For this purpose, we have developed the imaging system using the three 2 mm CdTe-DSDs. The 2 mm CdTe-DSD provides high sensitivity in a high-energy region up to 300 keV. In this work, we performed muon experiment using three 2 mm CdTe-DSD for elemental imaging. The muon experiment was conducted at MUSE of J-PARC.
