Elimination of the numerical Cerenkov instability for spectral EM-PIC codes
Peicheng Yu, Xinlu Xu, Viktor K. Decyk +7
When using an electromagnetic particle-in-cell (EM-PIC) code to simulate a relativistically drifting plasma, a violent numerical instability known as the numerical Cerenkov instabi…
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…
