2023-12-07 Multi-GeV cascaded laser wakefield acceleration in a hybrid capillary discharge waveguide doi:10.57760/sciencedb.14012 en Based on a 6 cm-long two-segment hybrid capillary discharge waveguide, a multi-GeV electronbeam with energy up to 3.2 GeV and 9.7% rms energy spread was achieved in a cascaded laserwakefield acceleration scheme, powered by an on-target 210 TW laser pulse. The electron beamwas trapped in the first segment via ionization-induced injection, and then seeded into the secondsegment for further acceleration. The long-distance stable guiding of the laser pulse andsuppression of the dark current inside the second-segment capillary played an important role inthe generation of high-energy electron beams, as demonstrated by quasi-three-dimensionalparticle-in-cell simulations. laser wakefield acceleration; capillary discharge waveguide; ionization-induced injection; high-energy electron beams; particle-in-cell-simulations Zhiyong Qin Wentao Li Jiaqi Liu Jiansheng Liu Wentao Wang Changhai Yu Zhijun Zhang Xinliang Wang Jinfeng Li Yuxin Leng Xiaoyan Liang Ruxin Li Zhizhan Xu PUBLIC https://creativecommons.org/licenses/by-nc-nd/4.0/ dataset http://www.doi.org/https://doi.org/10.1088/1367-2630/ac81e2 Science Data Bank
