Outline of Annual Research Achievements

始原隕石などを用い模擬分析実験を行うことで、「はやぶさ２」でもたらされる地球外物質の分析体制の整備と分析手法の高度化を行った。「はやぶさ」などサンプルリターンで得られる試料は極微小量のため、高感度かつ高空間分解能の分析機器を使用し、微小な領域から最大の化学的情報を取り出すことが非常に重要になる。そこで地球外有機物と含水鉱物を含む炭素質隕石、及び数10ミクロンの超炭素質宇宙塵などを「はやぶさ２」の模擬試料として使用する事で、試料加工から分析までの手法の高度化を進めた。
「はやぶさ２」の主たる分析対象の有機物や水は地上の汚染に敏感である。従って、試料の準備、輸送時の汚染を避けるだけではなく、試料加工から分析に至るプロセスでも汚染を防ぐ手法を開発する事で、試料の高精度分析が初めて可能となる。非汚染で回収されるリュウグウ小惑星試料(特に有機物)は、汚染を防ぐシステムがない場合には、試料作成、試料の研究機関間の輸送、機器間の試料搬送や分析する際に地球大気や地球由来の物質の影響を多大に受ける。この影響を避けるために、大気非曝露分析加工システムを構築した。これは共通グローブボックス（UVSOR, SPring8, 高知コア研究所所有）を拠点として、大気非曝露対応装置および専用の非曝露搬送機構（UVSORのSTXMとSPrin8のXCTは稼働中）を駆使することで、サンプリング、FIB-SEMによる試料加工からNanoSIMSによる微小領域イメージング分析までを大気非曝露下で実施するシステムとなる。NanoSIMS用大気非曝露搬送機構は、北海道大学GFCとの共同開発であり、知財（特許）として登録を進めている。
