Experimental simulation of the closed deivertor system for nuclear fusion

Abstract

In this study, we present the experimental simulation of the deivertor target geometry via detached plasma formation of hydrogen plasma in a linear divertor plasma simulator TPD-SheetIV. Three types of target geometry (V-shaped, oblique, and vertical targets) have been investigated. The eletron temperature (Te) and density (ne) of the plasma are measured with Langmuir probe. It is also intended to show that the observed hydrogen Lyman spectra could be explained by recombination processes. The V-shaped target enhances the recycling and reduction in heat load.
