【摘要】 介绍了在“神光”装置上进行的不同类型腔靶Ｘ射线面、体发射物理机制的实验研究。实验采用波长为１．０５３μｍ的激光，脉冲波形为高斯型，能量为５００一７００Ｊ／束，脉冲宽度为６００一１０００ｐｓ．典型靶由三个柱型腔组成，采取双束对打，两端的腔为吸收－转换区（源区），中间腔为辐射加热的内爆区。给出源区及内爆区Ｘ射线面、体发射测量结果，并通过分析、估算给出面、体发射强度比。更多还原

【Abstract】 We present the studies of physical mechanisms of wall and volume emissions of X-ray for different type cavity targets on “Shen-guang”facility.The wavelength1.053μm,pulse shape-Gauss type,energy～500一700J/beam,pulse width～600一1000ps laser are used to irradiate cylindrical Hohlraum from two ends.The typicaltarget consists of three cylindrical sections of which two ends are absorption-Conver-sion regions of laser energy(source region),and the median is imploding region,which is heated by radiation energy from source region. The experiment results ofX- ray wall and volulne emission and some analyses are presented.更多还原
