Successive innovations in particle accelerators have continually expanded the frontiers of scientific discovery. Laser wakefield accelerators promise to transform science, medicine…
Focal-point scanning for dose delivery and optimization with focused laser-accelerated very-high-energy electron beams
Zhiyuan Guo, Yifei Pi, Junwei Zhou +10
Focused very-high-energy electron (VHEE) beams can produce localized dose enhancement at selected depths, but irradiation of a finite target requires coordinated control of multipl…
Terahertz-based longitudinal phase space diagnostics of laser wakefield accelerated electron beams
Zhihao Chen, Yu Fang, Ran Li +5
Femtosecond relativistic electron beams are key probes of ultrafast dynamics, and their pulse duration directly limits the achievable temporal resolution. Laser wakefield accelerat…
Absolute charge calibration of DRZ phosphor screens for relativistic electron bunches
Shuang Liu, Bing Zhou, Pengwei Huang +9
Laser-plasma accelerators have been the subject of extensive research in recent years. The electron beams they generate exhibit a broad energy spread. To conveniently characterize…
Evolution of Quadrupole Wakefield Driven by Transversely Asymmetric Electron Beams in Hollow Plasma Channels
Siqin Ding, Jianfei Hua, Fei Li +2
Plasma wakefield acceleration in hollow plasma channels has emerged as a promising approach for positron acceleration, since an electron beam can drive wakes with a transversely un…
