HL-2A装置上灰尘研究的初步结果

摘要

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.%利用 HL-2A 装置原有的可见光 CCD UC-610 相机观测到了在等离子体放电过程中存在大量的灰尘,并通过扫描电子显微镜(SEM)和 X 射线能谱仪(EDX)了解到了辐照石墨样品的表面形貌及杂质元素成分.
