Following the IAEA Technical Meeting on 'Advanced Methodologies for the Analysis of Materials in Energy Applications Using Ion Beam Accelerators', this paper reviews the current status of ion beam analysis (IBA) techniques and some aspects of ion-induced radiation damage in materials for the field of materials relevant to fusion. Available facilities, apparatus development, future research options and challenges are presented and discussed. The analysis of beryllium and radioactivity-containing samples from future experiments in JET or ITER represents not only an analytical but also a technical challenge. A comprehensive list of the facilities, their current status, and analytical capabilities comes alongside detailed descriptions of the labs. A discussion of future issues of sample handling and the current status of facilities at JET complete the technical section.To prepare the international IBA community for these challenges, the IAEA technical meeting concludes the necessity for determining new nuclear reaction cross-sections and improving the inter-laboratory comparability by defining international standards and testing these via a round-robin test.

IAEA技術会合「イオンビーム加速器を用いたエネルギー応用材料の先進分析法」に続き、本論文は、核融合関連材料分野におけるイオンビーム分析(IBA)技術の現状と、イオン誘起放射線損傷の一部の側面を概説する。利用可能な施設、装置開発、将来の研究課題と挑戦について提示し、議論する。JETやITERにおける将来の実験から得られるベリリウムおよび放射性試料の分析は、分析上の課題であるだけでなく、技術的な課題でもある。施設の包括的なリスト、その現状、分析能力は、実験室の詳細な説明とともに提示される。試料取り扱いに関する将来の問題と、JETにおける施設の現状についての議論が、技術セクションを締めくくる。国際的なIBAコミュニティをこれらの課題に向けて準備させるため、IAEA技術会合は、新しい核反応断面積の決定と、国際標準の定義およびラウンドロビンテストによる実験室間比較の改善の必要性を結論付けた。
