Motivation: The CRP F11023 on “Development and Application of Ion Beam Techniques for Materials Irradiation and Characterization Relevant to Fusion Technology” has been motivated by the findings and recommendations of the experts who participated in the Technical Meeting on “Advanced Methodologies for the Analysis of Materials in Energy Applications Using Ion Beam Accelerators” organized in October 2018 by the IAEA Physics Section. These recommendations can be found in the report of this Technical Meeting report_Technical-Meeting_Oct2018_FINAL_10-09-2020_final.pdf.

Scientific background of the CRP: The physical conditions dominating in fusion are extreme and most demanding for the materials to be employed in fusion energy systems. As a result there are worldwide increasing efforts to investigate the physical processes altering the surface and composition of these materials under such conditions. The major scientific & technological challenges hereby are:

  • Understanding of all plasma-wall interactions (PWI), i.e. the processes involved in the energy and mass exchange between the plasma and the surrounding materials and components.
  • Development of proper Plasma Facing Materials (PFM), i.e. the materials constituting the wall and facing the plasma, with specific physical, chemical, and thermo-mechanical properties securing a long-term superior performance. These properties undergo severe modifications due to the intense irradiation of PFM's by ions, electrons, neutrons, and photons originating from nuclear and electronic processes during operation of the fusion device.

A detailed assessment of materials employed in a fusion environment requires thorough analyses before and after their exposure to the plasma. The final aim is to obtain an as complete as possible pattern of material modification and migration arising from erosion-deposition phenomena. To achieve this goal, accelerator-based Ion-Beam Analysis (IBA) methods can be extensively employed as they are crucial tools for analyzing materials, due to their sensitivity and depth-profiling ability.

Overall  CRP Objective:  Bring together scientists in both developing and developed Member States to collaborate on Ion-Beam Analysis (IBA) techniques in support of fusion research. 

Specific Objectives: 

  • Facilitate scientists from IAEA Member States (MS) to acquire knowledge and develop skills in irradiation and analysis of materials by accelerator-based techniques for fusion related applications
  • Provide a platform for the establishment of efficient collaborations and transfer of knowledge between scientists from developing & developed MS focused on the use of accelerator-based techniques for fusion related technologies.
  • Develop worldwide standards for measurements and analysis procedures of materials relevant to fusion research.

Expected Outputs:

  • Data on specific nuclear reaction cross sections and stopping powers required for characterization of Plasma-Facing Materials and Components
  • Reference samples for calibration and data analysis purposes
  • International standards and protocols for credible measurements and analysis procedures
  • Inter-comparison of the experimental capabilities and related analytical reliability of IBA facilities participating in a Round-Robin Exercise.

Workplan: The CRP's workplan includes three major work packages:

  1. Work Package 1: Experiments to determine original new nuclear data relevant to the scientific goals of the CRP. These include measurements and/or validation of new/existing reaction cross sections as well as measurements of stopping powers
  2. Work Package 2: Round Robin exercise(s) to evaluate the performance of IBA laboratories world-wide for experiments of ion-induced radiation damage in materials relevant to fusion energy, including post irradiation analysis.
  3. Work Package 3: Development of international good practices and procedures necessary for the standardization of IBA techniques for Materials Irradiation and Characterization Relevant to Fusion Technology.

Research priorities – Proposal evaluation and acceptance: The Ion Beam Analysis (IBA) of materials is a wide research field covering a large mass range and types of materials, which might not have direct relevance to the goals of the CRP. Therefore, research proposals submitted for evaluation, which are not addressing the CRP's work programme priorities will be rejected. For this reason, detailed guidelines for proposers can be found in crp_f11023_guidelines_for_proposers.pdf.

What is a CRP: Coordinated Research Projects (CRPs) are joint international projects bringing together scientists from research institutes in both developing and developed Member States to collaborate on research topics of common interest. Each CRP consists of a network of typically 10 to 15 research institutes that work in coordination for three to five years to acquire and disseminate new knowledge. Support to CRP member institutes is granted through research, technical and doctoral contracts. Cost-free research agreements are also established, primarily with institutions from developed countries. The IAEA acts as the sponsoring and coordinating body of the CRP and for this purpose an IAEA scientist is assigned to lead each CRP as the project officer. During the period of a CRP, research coordination meetings (RCMs) are organized for all CRP participants to present the progress of their work and schedule joint activities for the future. All CRP participants receive travel support to attend the RCMs. Common CRP outputs are the establishment of networks, databases, the development of testing devices or diagnostic tools, publications [4], as well as Master's and PhD theses.
