Propagation instabilities of high-intensity laser-produced electron beams
Physical Review Letters 90:17 (2003)
Abstract:
An innovative target design was used to perform the first studies of the propagation of very high current laser-produced electron beams in a regime relevant to the fast ignition scheme. Although it appears that (Weibel) and two-stream instabilities in plasmas where the beam density was close to the background plasma density-use of cone-guided schemes for fast ignition may be able to reduce the propagation distance of the electron beam and reduce the effect of these instabilities.Basic and integrated studies for fast ignition

Abstract:
The process of fast ignition (FI) using various laser systems was analyzed. A Petta watt (PW) laser system was used to study the basic elements relevant to FI, which could also be injected to a compressed core. Using a spherical target inserted with a Au cone guide for the PW laser pulse, an imploded core was heated upto 1 keV resulting in neutron increase which is 1000 times more than that without heating pulse.Propagation Instabilities of High-Intensity Laser-Produced Electron Beams
