我们提出了一个设计概念和模拟的性能紧凑的x射线，自由电子激光器驱动的超高梯度射频直线加速器。加速器的设计是基于LLNL/SLAC/LBL合作的高梯度技术的最新进展，以及BNL和LANL开发的明亮的高电流电子源。用这种加速器产生的GeV电子束可以通过Rocketdyne正在设计的短周期高场强摇摆器转换为2-10 nm范围内的软X射线。这种类型的线性光源可以产生极高光谱亮度的皮秒（或更短）脉冲串，适用于活体生物标本的闪光全息术和快速化学反应的研究。
We present a design concept and simulation of the performance of a compact x-ray, free electron laser driven by ultra-high gradient rf-linacs. The accelerator design is based on recent advances in high gradient technology by a LLNL/SLAC/LBL collaboration† and on the development of bright, high current electron sources by BNL and LANL. The GeV electron beams generated with such accelerators can be converted to soft x-rays in the range from 2-10 nm by passage through short period, high field strength wigglers as are being designed at Rocketdyne. Linear light sources of this type can produce trains of picosecond (or shorter) pulses of extremely high spectral brilliance suitable for flash holography of biological specimens in vivo and for studies of fast chemical reactions.
