Active feedback control of H-mode detachment via the divertor particle flux controller with divertor neon gas puffing in an H-mode plasma. The 2D contours of upper outer (UO) particle fluxes and strike point (SP) movements, i.e., distances from the UO diverotor corner, at port D and O are given in (a) and (b), respectively.
