Abstract

Abstract

In this paper, the electron temperature, electron density and areal density of imploded fuel pellet driven by SGⅡ laser were diagnosed through X-ray method. The electron temperature deduced from intensity ratio of Ly-beta line and He-beta line of Ar tracer doped in DD fuel was determined to be(950±100) eV. The electron density which was deduced from Stark broadening of He-beta line was determined to be (0.9±0.2)×1024cm-3. And the fuel areal density, which was deduced from X-ray monochromatic imaging of compressed fuel, was determined to be (3.2±0.5) mg/cm2.
