Stark manifold and projection merging
(part of theme Beam Stopping and Beam Emission Spectroscopy)
Objective
Hydrogen beam emission and MSE preparations for ITER will require increased use of full intensity picture of the resolved Balmer Stark multiplet and the replacement of calculated beam stopping with measurement of the beam emission for the deduction of localised neutral hydrogen beam density and deposition profiles. An enhanced support population model will be enabled which delivers a self-consistent Stark special feature (relativistic structure and cascade corrected) and beam stopping coefficients (enhanced field ionisation description) using the ADAS projection techniques.
Specific tasks
- Enable preparation of bundle-n GCR projection matrices for H-beams with motional Stark ionising fields.
- Map projection matrices to Stark manifold GCR population and emissivity model.
- Revision. Timing is subject to laboratory responses and indeterminate at this stage.
