X-ray diagnostics of laser indirect-driven implosion pellet
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)×10~(24)cm~(-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/cm~2.
