研究了由直线加速器相干光源自由电子激光器产生的10（16）W/cm（2）强飞秒X光脉冲辐照下介观单粒子的等离子体动力学。同时记录衍射图案和离子光谱允许消除激光聚焦体积强度和粒度分布的影响。数据显示，对于用强烈的X射线脉冲照射的簇，产生了窄分布的高电荷电离碎片，并且有效地抑制了纳米等离子体复合。
The plasma dynamics of single mesoscopic Xe particles irradiated with intense femtosecond x-ray pulses exceeding 10(16) W/cm(2) from the Linac Coherent Light Source free-electron laser are investigated. Simultaneous recording of diffraction patterns and ion spectra allows eliminating the influence of the laser focal volume intensity and particle size distribution. The data show that for clusters illuminated with intense x-ray pulses, highly charged ionization fragments in a narrow distribution are created and that the nanoplasma recombination is efficiently suppressed.
