Stark broadening of Balmer lines with low and moderate quantum number in dense divertor plasmas

Basil Duval, Kevin Henricus Annemarie Verhaegh

A computer simulation technique is applied to the modelling of Balmer line shapes in dense divertor conditions. The spectral profile of lines with a high principal quantum number n is sensitive to Stark broadening and can be used as a density diagnostic. I ...

Identification of the primary processes that lead to the drop in divertor target ion current at detachment in TCV

Kevin Henricus Annemarie Verhaegh, Mirko Wensing

Using SOLPS-ITER, we model a TCV conventional divertor discharge density ramp to understand the role of various processes in the loss of target ion current. We find that recombination is not a strong contributor to the rollover of the target ion current at ...
