| Description: |
Spectroscopic measurements of the hydrogenic Balmer-a and Balmer-y line emission in JET-ILW low- confinement mode (L-mode) deuterium plasmas are used to assess the onset of volume recombination in the low-field side (LFS) divertor. The evolution of the EDGE2D-EIRENE predicted Balmer-y to Balmer-a emission ratio from low-recycling to detached conditions is in qualitative agreement with the measured ratio. In low- recycling conditions the EDGE2D-EIRENE predicted line-emission is within 30% of measured emission, in high-recycling within 20%t, and in detached conditions lower by a factor of 2.5. ; Peer reviewed |
