利用１０道滤波荧光谱仪（ＦＦＳ）研究了强激光和薄壁腔靶相互作用时超热电子产生的特征，结合ＧａＡｓ硬Ｘ射线角分布探头、受激喇曼散射光探头、针孔相机的测量结果，分析得出：在内爆腔靶中，超热电子产生在源区，大部分超热电子被静电场和转换体约束在源区，只有小部分能量较高的超热电子进入到内爆区；内爆靶区超热电子总能量占超热电子总能量的约２０％，占入射激光能量的１％—２％。
The characteristics of superheated electrons generated by the interaction between intense laser and thin-walled cavity were studied by using 10-channel fluorescence spectrometer (FFS). Combining the measurements of GaAs hard X-ray angle probe, stimulated Raman scattering light probe and pinhole camera The results show that in the implosion chamber target, hot electrons are generated in the source region, most of the hot electrons are confined by the electrostatic field and the converter in the source region, and only a small fraction of the hot electrons with higher energy enters Blasting area; the total energy of the hot electron in the target area of implosion accounts for about 20% of the total energy of the hot electron and 1% -2% of the incident laser energy.
