Magnetized Current Filaments as a Source of Circularly Polarized Light
U. Sinha, J. Martins, J. Vieira +3
We show that the Weibel or currente filamentation instability can lead to the emission of circularly polarized radiation. Using particle-in-cell (PIC) simulations and a radiation p…
Experimental observation of proton bunch modulation in a plasma, at varying plasma densities
E. Adli, A. Ahuja, O. Apsimon +109
We give direct experimental evidence for the observation of the full transverse self-modulation of a relativistic proton bunch propagating through a dense plasma. The bunch exits t…
A compact tunable polarized X-ray source based on laser-plasma helical undulators
Ji Luo, Min Chen, Ming Zeng +7
Laser wakefield accelerators have great potential as the basis for next generation compact radiation sources because their accelerating gradients are three orders of magnitude larg…
Self-modulation instability of ultra-relativistic particle bunches with finite rise times
J. Vieira, L. D. Amorim, Y. Fang +3
We study the evolution of the self-modulation instability using bunches with finite rise times. Using particle-in-cell simulations we show that unlike long bunches with sharp rise…
Electromagnetic field generation in the downstream of electrostatic shocks due to electron trapping
A. Stockem, T. Grismayer, R. A. Fonseca +1
A new magnetic field generation mechanism in electrostatic shocks is found, which can produce fields with magnetic energy density as high as 0.01 of the kinetic energy density of t…
Electron trapping and acceleration by the plasma wakefield of a self-modulating proton beam
K. V. Lotov, A. P. Sosedkin, A. V. Petrenko +6
It is shown that co-linear injection of electrons or positrons into the wakefield of the self-modulating particle beam is possible and ensures high energy gain. The witness beam mu…
