In 2004, using a 3D particle-in-cell ͑PIC͒ model ͓F. ͑2004͔͒, it was predicted that a 16.5 TW, 50 fs laser propagating through nearly 0.5 cm of 3 ϫ 10 18 cm −3 preformed plasma channel would generate a monoenergetic bunch of electrons with a central energy of 240 MeV after 0.5 cm of propagation. In addition, electrons out to 840 MeV were seen if the laser(More)
The interaction of intense lasers with solid matter generates a hot plasma state that is well described by the Vlasov–Fokker–Planck equation. Accurate and efficient modeling of the physics in these scenarios is highly pertinent, because it relates to experimental campaigns to produce energy by inertial confinement fusion on facilities such as the National(More)
Accelerators are the largest and most costly scientific instruments of the Department of Energy, with uses across a broad range of science, including colliders for particle physics and nuclear science and light sources and neutron sources for materials studies. COMPASS, the Community Petascale Project for Accelerator Science and Simulation, is a broad,(More)
— We use the quasi-static particle-in-cell code Quick-PIC to perform full-scale, one-to-one LWFA numerical experiments , with parameters that closely follow current experimental conditions. The propagation of state-of-the-art laser pulses in both preformed and uniform plasma channels is examined. We show that the presence of the channel is important(More)
