实验靶对半黑腔辐射源辐射温度的影响

间接驱动惯性约束聚变和高能量密度物理实验中使用黑腔作为强X射线辐射源，黑腔源靶的等效辐射温度受安装在辐射出口的实验用靶的影响而与单独进行辐射源特性研究时有所不同。通过对几种不同辐射输运靶对半黑腔辐射源的影响进行的实验研究发现，添加不同填充材料的输运管能够使测量到的黑腔辐射源的辐射温度升高3~8 eV。实验结果的统计显示，输运管越长，填充材料密度越大，辐射温度越高。

Influence of different targets on halfraum radiation source temperature

Hohlraums/halfraums are used as an intensive X-ray radiation sources in indirect drive inertial confinement fusion and high energy density physics experiments to study material properties and physical problems like radiation transport. The equivalent radiation temperatures of the hohlraums are different from those with experimental targets attached on the wall. Experiments are carried out to study influence of different types of foam-filled cylinders attached to the halfraum bottom and 3-8 eV increase of the halfraum radiation source temperature is found. The statistics show that the radiation temperatures are higher with longer and denser-foam-filled cylinders.
