Electron Trapping in Self-Modulated Laser Wakefields by Raman Backscatter.
Abstract
Simultaneous measurements of high energy electrons and plasma wave characteristics have been conducted in a self-modulated laser wakefield accelerator. Approximately 10(exp 8) electrons were accelerated from the background plasma to energies greater than 1 MeV with a peak energy of approximately 30 MeV. A strong correlation between the plasma wave amplitude and electron production was measured with no evidence of wave breaking. Simulations indicate plasma electrons are trapped by the low phase velocity beat waves produced by backward Raman scattering.
