Journal ArticleDOI
Simulation techniques for heavy ion fusion chamber transport
TL;DR: In this paper, a hybrid implicit algorithm was developed to treat dense plasmas accurately, and simulations of neutralized ballistic transport showed improved transport efficiency for a 4-GeV, 4-kA Pb ion beam by including a 1013 cm−3 plasma at initialization.
Journal ArticleDOI
Integrated simulation of the generation and transport of proton beams from laser-target interaction
TL;DR: In this article, a hybrid particle-in-cell (HPC) code is used to simulate the laser-plasmas interaction and its effect on the electron production and transport, as well as the distributed acceleration and spatial distribution.
Journal ArticleDOI

TL;DR: Longitudinal compression of a velocity-tailored, intense neutralized beam at 300 keV, 25 mA has been demonstrated and has been confirmed independently with two different diagnostic systems.

TL;DR: The 80-TW "Z" pulsed power facility at Sandia National Laboratories as discussed by the authors is the largest pulsed-power device in the world today, and it can discharge up to 22'MJ of energy stored in its capacitor banks into a current pulse that rises in 100'ns and peaks at a current as high as 30 MA in low-inductance cylindrical targets.

TL;DR: In this paper, the authors developed conceptual designs of two petawatt-class pulsed-power accelerators: Z 300 and Z 800, which are based on an accelerator architecture that is founded on two concepts: single-stage electrical-pulse compression and impedance matching.
