Generation of attosecond x-ray pulses is attracting much attention within the x-ray free-electron laser (FEL) user community. We propose a novel scheme for the generation of coherent stable attosecond x-ray pulse trains in a seeded FEL. via a process of mode-locked amplification. Three modulators and two chicanes are used for generating separated attosecond scale microstructures in th... https://www.ealisboa.com/quick-save-Pentair-Female-to-Female-Hose-Adapter-4-For-Sectional-Hose-K21241B-top-mega/
