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…
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…
Relativistically Induced Transparency Acceleration (RITA) of Protons and Light-ions with Ultrashort Laser Interaction with Heavy-ion Plasma Density Gradient
Aakash A. Sahai, F. S. Tsung, A. R. Tableman +2
The relativistically induced transparency acceleration (RITA) scheme of proton and ion acceleration using laser-plasma interactions is introduced, modeled, and compared to the exis…
