A method proposed most recently for heat flux reduction in a divertor is to use a so-called V-shaped target plate. A numerical study of neutral behavior around the V-shaped target in the divertor simulator, Test Plasma produced by Directed current device for sheet plasma (TPD-SheetIV), using DEGAS 2 is reported. The neutral distribution and H-alpha emission profile are modeled and compared for three types of targets, mainly for the low-density attached condition. Under this condition, excited atoms are produced by electron impact with recycled atoms near the target, and hence, H-alpha emission has a peak there.
