PLEIADES 是一种紧凑、可调谐、高亮度、超短脉冲、汤姆逊散射 X 射线源。硬 X 射线皮秒脉冲 (10–200 keV) 是通过超相对论 (20–100 MeV) 皮秒持续时间电子束与高强度亚皮秒 800 nm 激光脉冲碰撞而产生的。该源的初始运行使用 57 MeV、0.3 nC、50 μm rms 宽度电子束和 180 mJ、15 μm rms 宽度激光脉冲产生 78 keV X 射线，每个脉冲 106 个光子。发现源的角分布、能量和能谱与理论和模拟非常吻合。源优化预计可将 X 射线输出增加到每脉冲 107 至 108 光子，峰值亮度接近 1020 光子/秒/0.1% 带宽/mm2/mrad2。
PLEIADES is a compact, tunable, high-brightness, ultra-short-pulse, Thomson-scattering X-ray source. Picosecond pulses of hard X-rays (10–200 keV) are created by colliding an ultra-relativistic (20–100 MeV), picosecond-duration electron beam with a high-intensity, sub-picosecond, 800-nm laser pulse. Initial operation of this source has produced 78-keV X-rays with 106photons per pulse using a 57-MeV, 0.3-nC, 50-μm rms width electron beam and a 180-mJ, 15-μm rms width laser pulse. The angular distribution, energy, and energy spectrum of the source are found to agree well with theory and simulations. Source optimization is expected to increase X-ray output to between 107and 108photons per pulse with a peak brightness approaching 1020photons/s/0.1% bandwidth/mm2/mrad2.
