The strongly radiating regime of [[Scrape-Off Layer]]/[[divertor]] operation is one where the divertor <math>T_e</math> is low enough that a significant fraction of power flowing out of the core plasma is dissipated by hydrogen or impurity radiation.<ref name=stangeby_book_p184>[[doi:10.1201/9780367801489|P. Stangeby, "The Plasma Boundary of Magnetic Fusion Devices" (2000) p.184]]</ref> Although power conducted to the [[divertor]] target will be reduced, the radiated power can still produce a high heat load on the target if the radiation source is close to the target.<ref name=stangeby_book_p184></ref><ref>[[doi:10.1016/j.nme.2019.01.010|D.
