Crunch-in regime - Non-linearly driven hollow-channel plasma
Aakash A. Sahai
Plasma wakefields driven inside a hollow-channel plasma are significantly different from those driven in a homogeneous plasma. This work investigates the scaling laws of the accele…
Longitudinal instabilities affecting the moving critical layer laser-plasma ion accelerators
Aakash Ajit Sahai, Thomas C. Katsouleas
In this work we analyze the longitudinal instabilities of propagating acceleration structures that are driven by a relativistically intense laser at the moving plasma critical laye…
Self-injection by trapping of plasma electrons oscillating in rising density gradient at the vacuum-plasma interface
Aakash A. Sahai, Thomas C. Katsouleas, Patric Muggli
We model the trapping of plasma within the density structures excited by a propagating energy source () in a rising plasma density gradient. Rising density grad…
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…
