Experimental observation and computational modeling of radial Weibel instability in high intensity laser-plasma interactions

Autor: Ngirmang, Gregory K., Morrison, John T., George, Kevin M., Smith, Joseph R., Frische, Kyle D., Orban, Chris, Chowdhury, Enam A., Roquemore, W. Mel

When a relativistic intensity laser interacts with the surface of a solid density target, suprathermal electron currents are subject to Weibel instability filamentation when propagating through the thermal population of the bulk target. We present ti

We present an experimental demonstration of the efficient acceleration of electrons beyond 60 MeV using micro-channel plasma targets. We employed a high-contrast, 2.5 J, 32 fs short pulse laser interacting with a 5 \mu m inner diameter, 300 \mu m lon
