金箔靶背侧X光辐射的实验研究

Experimental Study of X Ray Emission from the Rear Side of Gold Foil

利用星光Ⅱ激光装置钕玻璃三倍频激光辐照金箔靶，实验研究了金箔靶背侧发射的Ｘ光能谱、时间过程和透过激光能量。结果表明：金箔背侧发射的Ｘ光可以作为一种较干净的强Ｘ光辐射源。

Temporal and spectral behaviors of X ray radiation emitted from the rear side of laser irradiated gold foil, and transmitted laser energy have been investigated experimentally. An X ray source with high X ray flux and low transmitted laser energy could be obtained in laboratory.
