| CRP Duration: |
Start date: 2001-08-01
Closed date: 2005-11-30 |
| Overall Objectives: |
The proposed CRP will cover significant developments that have occurred since completion of a related CRP in 1993 on the topic "Atomic and Molecular Data for Fusion Edge Plasmas". The new CRP will focus on the assessment and collection of new data for molecular processes in edge plasmas which are available from both experimental and theoretical studies, and the identification and fulfilment of new data requirements. |
| Research Outputs: |
This CRP has brought researchers together from 12 different institutions for collaboration on the CRP. At the initial RCM the participants identified specific areas in which they could make significant contributions to nuclear fusion research. These data are needed for modeling plasma processes in edge regions where temperatures and densities are such that a variety of molecules form and undergo a variety of reactions. These processes have a significant impact on the behavior of the plasma in the edge region. In addition, the interaction of the hydrogen isotopes with wall materials is extremely important in predicting the overall tritium build-up in future fusion devices, such as ITER. During the course of the CRP significant new results from both experiment and theory were reported. These new data have already had a significant effect on modeling calculations carried out using the well known B2-EIRENE code. Results from the CRP have also been evaluated and added to electronic databases maintained by the Atomic and Molecular Data Unit. In addition, all participants have submitted manuscripts for an issue of the Atomic and Plasma-Material Interaction Data for Fusion. |
| CRP Outcome (Effectiveness; Impact; Relevance): |
The specific objective to enhance the atomic and molecular databases for nuclear fusion energy research was fully achieved.
The results of this CRP have made a significant contribution to the enhancement of the atomic and molecular databases for nuclear fusion energy research.
The work of this CRP had a significant impact on the field of molecular processes in plasmas in the edge regions of fusion devices. These data are now being used in modeling such regions and will have an impact on design considerations for future devices.
This CRP was strongly recommended by the A+M Subcommittee of the International Fusion Research Council. These data are extremely important for understanding the molecular processes in edge plasmas, which can have a significant influence on the behavior of the overall fusion device. In addition, these data are of highest importance in processes involving tritium uptake and release in hydrocarbons, which readily form in the edge regions of fusion devices.
