Preliminary result of dust investigation on HL-2A tokamak

Abstract

Abstract:

Existence of flying dusty objects during plasma discharges was observed by a visible CCD UC-610 camera on HL-2A tokamak, and morphologies and impurity elements of irradiated graphite samples have been analyzed by scanning electron microscopy(SEM) and energy dispersive X-ray spectroscopy(EDX), respectively.
