半圆柱壳槽靶的激光等离子体软X射线光谱发射特点的研究

Investigation of soft X-ray emission characteristics of laser plasma in a half-cylindrical shell target

通常对一种半圆柱壳槽靶与平面靶激光等离子体软X射线光谱空间分布特点和流体动力学行为的比较,证实这种槽形靶可以有效地提高槽区内等离子体温度,从而增强该区域内的软X＇射线光谱发射.

Through the comparison of the soft X-ray emissive and hydrodynamic characters of a half-clindrical-shell-target and a planar target, we proved that this kind of grooved target can effectively increase the plasma temperature in the groovy region, hence Increase the soft X-ray emission in this region.
