Název v původním jazyce

Laser-driven low energy electron beams for single-shot ultra-fast probing of meso-scale materials and warm dense matter

Popis výsledku v původním jazyce

Laser wakefeld acceleration has proven to be an excellent source of electrons and X-rays suitable for ultra-fast probing of matter. These novel beams have demonstrated unprecedented spatial and temporal resolution allowing for new discoveries in material science and plasma physics. In particular, the study of dynamic processes such as non-thermal melt and lattice changes on femtosecond time-scales have paved a way to completely new scientifc horizons. Here, we demonstrate the frst single-shot electron radiography measurement using an femtosecond electron source based on the downramp-density gradient laser-wakefeld-acceleration with the use of a compact Ti:sapphire laser. A quasi-monoenergetic electron beam with mean energy of 1.9 ± 0.4 MeV and charge 77 ± 47 pC per shot was generated by the laser incident onto a gas target and collimated using a two ring-magnet beam path. High quality electron radiography of solid objects with spatial resolution better than 150 µm was demonstrated.
