Identification of the primary processes that lead to the drop in divertor target ion current at detachment in TCV
Abstract
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 detachment. In contrast, the divertor ion source appears to play a central role in magnitude (the source of most of the ion target current) and time, apparently dropping during the density ramps as a result of a drop in power available for ionization.
