研究・開発項目

• 高輝度放射光を利用したミクロンサイズ以下の単結晶および粉末試料1粒からの結晶構造解析法の開発
• 高輝度放射光を利用した迅速単結晶構造解析法の開発

主に単結晶構造解析ビームラインBL02B1と高フラックスビームラインBL40XUにて実験を行っており、微小試料の迅速測定技術の開発を進めています。ビームラインの利用者に対して放射光でなければ測定のできない微小単結晶構造解析法を提供し、実験のサポートおよび共同研究を行っています。また、所内外で測定されたデータ解析についても相談を受け付け、利用者の構造解析レベルの向上に力を注いでいます。単結晶構造解析の他に、放射光のパルス性を利用した特殊な実験のための測定装置や測定ソフトウェアの開発も行っています。
