Phase-Space Shaping in Wakefield Accelerators due to Betatron Cooling
Pablo J. Bilbao, Thales Silva, Luis O. Silva
Plasma-based accelerators are beginning to employ relativistic beams with unprecedented charge and ultrashort durations. These dense driver beams can drive wakes even in high-densi…
The electron cyclotron maser instability in laser-ionized plasmas
Thales Silva, Pablo J. Bilbao, Luis O. Silva
We show that circularly polarized lasers create plasmas with long-lasting ring-shaped weakly relativistic momentum distributions which, in the presence of an ambient magnetic field…
Relaxation to universal non-Maxwellian equilibria in a collisionless plasma
Robert J. Ewart, Michael L. Nastac, Pablo J. Bilbao +3
Generic equilibria are derived for turbulent relaxing plasmas via an entropy-maximization procedure that accounts for the short-time conservation of certain collisionless invariant…
Weibel instability beyond bi-Maxwellian anisotropy
Thales Silva, Bedros Afeyan, Luis O. Silva
The shape of the anisotropic velocity distribution function, beyond the realm of strict Maxwellians can play a significant role in determining the evolution of the Weibel instabili…
