The formation of the radial electric field. $E_\textrm{r}$ in the scrape-off layer (SOL) has been experimentally studied for attached divertor conditions in stellarator W7-X. The main objective of this study is to test the validity in a complex three-dimensional (3D) island divertor of simple models. typically developed in tokamaks. https://www.jmannino.com/best-catch-University-of-Miami-The-U-iPhone-14-Plus-Clear-Case-p36265-quick-deal/
