Enhanced proton acceleration in an applied longitudinal magnetic field
Alexey Arefiev, Toma Toncian, Gennady Fiksel
Using two-dimensional particle-in-cell simulations, we examine how an externally applied strong magnetic impacts proton acceleration in laser-irradiated solid-density targets. We f…
A Relativistic Plasma Polarizer: Impact of Temperature Anisotropy on Relativistic Transparency
David J. Stark, Chinmoy Bhattacharjee, Alexey V. Arefiev +2
3D particle-in-cell simulations demonstrate that the enhanced transparency of a relativistically hot plasma is sensitive to how the energy is partitioned between different degrees…
Temporal resolution criterion for correctly simulating relativistic electron motion in a high-intensity laser field
Alexey V. Arefiev, Ginevra E. Cochran, Douglass W. Schumacher +2
Particle-in-cell codes are now standard tools for studying ultra-intense laser-plasma interactions. Motivated by direct laser acceleration of electrons in sub-critical plasmas, we…
Compact tunable Compton x-ray source from laser-plasma accelerator and plasma mirror
Hai-En Tsai, Xiaoming Wang, Joseph Shaw +8
We present an in-depth experimental-computational study of the parameters necessary to optimize a tunable, quasi-monoenergetic, efficient, low-background Compton backscattering (CB…
New mechanisms for generating super-ponderomotive electrons in laser-irradiated targets
A. V. Arefiev, A. P. L. Robinson, V. N. Khudik +2
It is shown that static longitudinal and transverse electric fields can significantly alter electron acceleration by a long laser beam in a sub-critical plasma, enabling generation…
