Opacity Study on Dense D_2, Mixtures of Hydrogen and Deuterium Plasma Generated by Shock Compression

用强平面激波对氘和氢氘等摩尔混合气体进行冲击压缩 ,产生密度约为 3.7× 10 - 3 — 7.0×10 - 3 g/cm3 等离子体 .由记录的等离子体发光过程的上升前沿 ,确定了氘和氢氘等离子体光谱吸收系数随光学波长变化 .

Plasma is generated by passage of strong planar shock wave through gas. Initial experiments in deuterium and equal mol mixture of hydrogen and deuterium have been performed to produce plasma with 3.7×10 -3-7.0×10 -3 g/cm 3density. The variation of the opacity of the plasma with wavelength is measured by recording the risetime of the emitted light.
