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…
Refraction of beams due to plasma lensing at a plasma-vacuum interface -- applied to beam deflection in a Copper cell with electrical RF-breakdown plasma
Aakash A. Sahai, T. C. Katsouleas
We formulate a possible description of the deflection of a relativistic beam in an inhomogeneous copper plasma, encountered by the beam when propagating through a acceleratin…
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…
