    • An apparatus and method for the generation of ultrabright multikilovolt x-rays from saturated amplification on noble gas transition arrays from hollow atom states is described. Conditions for x-ray amplification in this spectral region combine the production of cold, high-Z matter, with the direct, selective multiphoton excitation of hollow atoms from clusters using ultraviolet radiation and a nonlinear mode of confined, self-channeled propagation in plasmas. Data obtained is consistent with the presence of saturated amplification on several transition arrays of the hollow atom Xe(L) spectrum (&lgr;˜2.9 Å). An estimate of the peak brightness achieved is ˜1029 &ggr;·s−1·mm−2·mr−2 (0.1% Bandwidth)−1, that is ˜105-fold higher than presently available synchotron technology.
    • 描述了从空心原子状态的稀有气体过渡阵列上的饱和放大产生超立方多千伏X射线的装置和方法。 在该光谱区域中的x射线放大的条件将冷,高Z物质的产生与使用紫外辐射的簇的空心原子的直接,选择性多光子激发和等离子体中的限制,自通道传播的非线性模式相结合。 获得的数据与空心原子Xe(L)光谱(λ〜2.9)的几个过渡阵列上存在饱和扩增一致。 所获得的峰值亮度的估计为〜10 29Ω-1 -1 mm -2(0.1%带宽)< - 1>,即〜10 -5 - 高于目前可用的同步电子技术。

    • The generation of ultrabright, multikilovolt coherent tunable x-radiation resulting from amplification on hollow atom transition arrays is described. Amplification has been demonstrated by physical evidence including (a) the observation of selected spectral components of several Xeq+ hollow atom transition arrays (q=30, 31, 32, 34, 35, 36, 37) radiated axially from confined plasma channels, (b) the measurement of line narrowing that is spectrally correlated with the amplified transitions, (c) evidence for spectral hole-burning in the spontaneous emission, a manifestation of saturated amplification, that corresponds spectrally with the amplified lines, and (d) the detection of an intense narrow (δθx˜0.2 mr) directed beam of radiation in the far field of the source.
