Enhancement of pair creation due to locality in bound-continuum interactions
D. D. Su, Y. T. Li, Q. Z. Lv +1
Electron-positron pair production from vacuum is studied in combined background fields, a binding electric potential well and a laser field. The production process is triggered by…
Mapping electromagnetic fields structure in plasma using a spin polarized electron beam
X. Y. An M. Chen, J. X. Li, S. M. Weng +3
We propose a scheme to mapping electromagnetic fields structure in plasma by using a spin polarized relativistic electron beam. Especially by using Particle-in-Cell (PIC) and elect…
Phase space dynamics of a plasma wakefield dechirper for energy spread reduction
Y. P. Wu, J. F. Hua, Z. Zhou +12
Plasma-based accelerators have made impressive progress in recent years. However, the beam energy spread obtained in these accelerators is still at ~ 1 % level, nearly one order of…
