飞秒激光-固体靶相互作用中γ射线发射研究
A study for the γ-ray emission in femtosecond laser-solid target interaction
摘要
Abstract
The space distribution and energy distribution of γ-ray from the interaction of femtosecond laser-solid target have been measured by using LiF thermoluminescence dosimeters (TLDs) which had been calibrated absolutely with a137Cs-γ radiocesium. The result shows that the γ-ray emission located mainly in the directions of the specular reflection of laser and the target normal. The γ-ray spectrum is a Maxwellian-like distribution, fitted with Maxwellian distribution, the temperature of γ-ray is about 12. 52 keV which is more consistent with a result from the other experiment.关键词
