Ion acceleration by superintense laser-plasma interaction

A Macchi, M Borghesi, M Passoni - Reviews of Modern Physics, 2013 - APS
Ion acceleration driven by superintense laser pulses is attracting an impressive and steadily
increasing effort. Motivations can be found in the applicative potential and in the perspective …

Observation of magnetic field generation via the Weibel instability in interpenetrating plasma flows

CM Huntington, F Fiuza, JS Ross, AB Zylstra… - Nature Physics, 2015 - nature.com
Collisionless shocks can be produced as a result of strong magnetic fields in a plasma flow,
and therefore are common in many astrophysical systems. The Weibel instability is one …
