Downramp-assisted underdense photocathode electron bunch generation in plasma wakefield accelerators
Alexander Knetsch, Oliver Karger, Georg Wittig +12
It is shown that the requirements for high quality electron bunch generation and trapping from an underdense photocathode in plasma wakefield accelerators can be substantially rela…
Reducing ion energy spread in hole-boring radiation pressure acceleration by using two-ion-species targets
S. M. Weng, M. Murakami, Z. M. Sheng
The generation of fast ion beams in the hole-boring radiation pressure acceleration by intense laser pulses has been studied for targets with different ion components. We find that…
Enhanced laser-driven electron beam acceleration due to ionization-induced injection
Song Li, Nasr A. M. Hafz, Mohammed Mirzaie +5
We report an overall enhancement of a laser wakefield acceleration (LWFA) using the ionization injection in a mixture of 0.3 % nitrogen gas in 99.7 % helium gas. Upon the interacti…
Enhanced electron yield from a laser-plasma accelerator using high-Z gas jet targets
Mohammad Mirzaie, Nasr A. M. Hafz, Song Li +5
An investigation of the multi-hundred MeV electron beam yield (charge) form helium, nitrogen, neon and argon gas jet plasmas in a laser-plasma wakefield acceleration experiment was…
Investigation of transient surface electric field induced by femtosecond laser irradiation of aluminum
Run-Ze Li, Pengfei Zhu, Long Chen +5
Transient surface electric fields induced by femtosecond laser irradiation of an aluminum film were investigated directly by ultrashort electron pulses. At pump intensities of 2.9~…
Coherent keV backscattering from plasma-wave boosted relativistic electron mirrors
F. Y. Li, Z. M. Sheng, M. Chen +5
A new parameter regime of laser wakefield acceleration driven by sub-petawatt femotsecond lasers is proposed, which enables the generation of relativistic electron mirrors further…
