Transverse instability in the "light sail" ion acceleration
Y. Wan, I. A. Andriyash, W. Lu +2
Acceleration of ultrathin plasma foils by laser radiation pressure promises compact alternatives to the conventional ion accelerators. It was shown, that a major showstopper for su…
Optimizing Laser Wakefield Acceleration in the Nonlinear Self-Guided Regime for Fixed Laser Energy
A. Davidson, A. Tableman, P. Yu +5
The scaling laws for laser wakefield acceleration in the nonlinear, self-guided regime [Lu et al. Phys. Rev. Spec. Top. Accel. Beams 10, 061301 (2007)] are examined in detail using…
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…
Ion motion in the wake driven by long particle bunches in plasmas
J. Vieira, R. A. Fonseca, W. B. Mori +1
We explore the role of the background plasma ion motion in self-modulated plasma wakefield accelerators. We employ J. Dawson's plasma sheet model to derive expressions for the tran…
Proton acceleration by a relativistic laser frequency-chirp driven plasma snowplow
Aakash A. Sahai, T. C. Katsouleas, R. A. Bingham +4
We analyze the use of a relativistic laser pulse with a controlled frequency chirp incident on a rising plasma density gradient to drive an acceleration structure for proton and li…
Long Term Evolution of Plasma Wakefields
Aakash A. Sahai, T. C. Katsouleas, F. S. Tsung +1
We study the long-term evolution (LTE) of plasma wakefields over multiple plasma-electron periods and few plasma-ion periods, much less than a recombination time. The evolution and…
