CXS data and fiducial embedding
(part of theme Charge Exchange Spectroscopy)
Objective
Objectives The fundamental state-selective charge exchange cross-section database for sub-dominant levels depends on the CTMC model for energies >~50 keV/amu. relevant to ITER . Extension of the database to receiver charge states >10 needs the improved CTMC approximation. Calculations, currently extending to z=18, are required to substantially higher charge states and n-shells to satisfy the fusion application need and to revise the present universal parametric forms. Higher precision calculations at lower energy <~ 50keV for Ar+16 - Ar+18 in CCMO and CCAO approximation will support the next phase of CXS diagnostic development.
Specific tasks
- Procure level 1 improved CTMC state selective charge exchange data for receiver charges >~16. Embed in ADAS adf01 format and derive extrapolation parameters. Develop error estimates for CTMC Vs improved CTMC .
- Revise universal n- and l- shell parametric forms at higher charge state and beam energies >~50keV/amu .
- Procure level 2 state selective charge exchange cross-section data for charge state >~16 in CCAO and CCMO approximation at energies <~50 keV/amu. Update CCAO/CCMO for light element nuclei. Revise ADAS adf12 effective emission coefficients.
- Revision. Timing is subject to laboratory responses and indeterminate at this stage.
