| CRP Duration: |
Start date: 2001-07-15
Closed date: 2005-11-30 |
| Overall Objectives: |
The principle objective of this CRP is to identify the needs for atomic and molecular (A+M) data for the diagnostics of core and edge plasmas and for the diagnostics of the velocity distribution of fusion alpha particles. This CRP will focus on the various types of diagnostic methods currently used in large machine plasma diagnostics such as plasma impurity emission, charge exchange diagnostics, neutral beam based emission diagnostics, and the plasma neutrals analysis method for the alpha particle diagnostics. |
| Research Outputs: |
This CRP has brought researchers together from 11 different institutions for collaboration on data for plasma diagnostics for fusion devices. At the initial RCM specific data needs were identified and a detailed work plan was established. At the second RCM very good progress had been made, but areas of further research were identified. The CRP was extended for a third RCM at which time final results were reported. Significant new data for processes important to diagnostics, especially in edge plasmas, were reported. Of major significance were new cross sections on state selective charge exchange processes, especially involving alpha particles colliding with low charge state ions. Results from the CRP were published in numerous articles in refereed journals during the course of the CRP. |
| 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 data for plasma diagnostics. These data are needed modeling the plasma in different regimes in order to determine parameters such as density and temperature. Since many of these data were not known for many plasma conditions, this CRP has had a significant impact on the ability to model the behavior of neutral beam injection as well as interactions of the plasma with cool particles sputtered from the plasma facing components.
This CRP was strongly recommended by the A+M Subcommittee of the International Fusion Research Council. These data produced are vital for the diagnostics of the plasma processes occurring in nuclear fusion reactors. It is especially important to generate the cross section data for state selective processes from which characteristic radiation can be used for deriving the physical conditions of the plasma.
