一个紧凑的软X射线源，使用汤姆逊散射，使皮秒激光器和电子射频枪的组合，旨在生物学研究，如使用X射线显微镜。X射线源包括光电注入器系统和皮秒激光系统，桌面尺寸为2× 2 m2。从全固态锁模Nd：YLF激光器系统中获得了波长为1047 nm的红外激光，并注入到加速器系统的光电阴极中。用激光驱动光阴极射频电子枪系统产生了4.2MeV电子束。用闪光灯泵浦的激光放大器将剩余激光束放大到约4.2mJ/脉冲。当电子束与放大的激光束碰撞时，通过汤姆逊背散射产生300 eV的软X射线。利用同一种子激光脉冲照射光阴极，并与激光光子发生散射，实现了两束光的稳定相互作用。
A compact soft x-ray source using Thomson scattering, enabled by the combination of a picosecond laser and an electron rf gun, was developed aiming at biological studies such as those using an x-ray microscope. The x-ray source included both a photoinjector system and a picosecond laser system with a tabletop size of 2×2m2. An infrared laser beam (λ0=1047nm) was obtained from an all-solid-state mode-locked Nd:YLF laser system and injected into the photocathode of an accelerator system. A 4.2MeV electron beam was generated from a laser-driven photocathode rf gun system. The residual laser beam was amplified up to about 4.2mJ/pulse using a flash-lamp-pumped laser amplifier. Upon collision of the electron beam with the amplified laser beam, 300eV soft x rays were generated by Thomson backscattering. The stable interaction between the two beams was achieved using the same seed laser pulse for irradiating the photocathode and the scattering process with laser photons.
