Journal ArticleDOI
Electron-hose instability in the ion-focused regime.
TL;DR: The asymptotic growth of beam-centroid oscillations is computed, and the growth length is found to be very rapid, indeed much less than the betatron period of the beam.
Journal ArticleDOI
Computational Methods in the Warp Code Framework for Kinetic Simulations of Particle Beams and Plasmas
Alex Friedman,Ronald H. Cohen,David P. Grote,Steven M. Lund,W.M. Sharp,Jean-Luc Vay,Irving Haber,R. A. Kishek +7 more
TL;DR: Warp as discussed by the authors is a framework for particle-in-cell simulations of space-charge-dominated ion beams in accelerators, for heavy-ion-driven inertial fusion energy, and related experiments.
Journal ArticleDOI
Results on intense beam focusing and neutralization from the neutralized beam experiment
Prabir K. Roy,Simon S. Yu,Shmuel Eylon,Enrique Henestroza,André Anders,F.M. Bieniosek,Wayne G. Greenway,B.G. Logan,William Waldron,D.L. Vanecek,Dale Welch,David V. Rose,Ronald C. Davidson,Philip Efthimion,Erik P. Gilson,Adam B Sefkow,W.M. Sharp +16 more
TL;DR: In this paper, a radial mesh liner that is positively biased inside a beam drift tube is used to suppress the unwanted secondary electrons produced at the wall by halo particle impact, and measurements of current transmission, beam spot size as a function of axial position, beam energy, and plasma source conditions are presented along with detailed comparisons with theory.
Journal ArticleDOI
An Updated Point Design for Heavy Ion Fusion
Simon S. Yu,Wayne R. Meier,Ryan P. Abbott,John J. Barnard,T. Brown,Debra Callahan,P. Heitzenroeder,Jeffery F. Latkowski,B.G. Logan,S.J. Pemberton,Per F. Peterson,David V. Rose,G. Sabbi,W.M. Sharp,Dale Welch +14 more
TL;DR: In this paper, an updated, self-consistent point design for a heavy ion fusion (HIF) power plant based on an induction linac driver, indirect-drive targets, and a thick liquid wall chamber has been completed.
Journal ArticleDOI
Recent US advances in ion-beam-driven high energy density physics and heavy ion fusion $
B.G. Logan,F.M. Bieniosek,Christine M. Celata,Joshua Coleman,Wayne G. Greenway,Enrique Henestroza,J.W. Kwan,Edward P. Lee,Matthaeus Leitner,Prabir K. Roy,Peter A. Seidl,Jean-Luc Vay,W.L. Waldron,Simon S. Yu,J.J. Barnard,Ronald H. Cohen,Alex Friedman,David P. Grote,M. Kireeff Covo,A.W. Molvik,S.M. Lund,Wayne R. Meier,W.M. Sharp,Ronald C. Davidson,P. C. Efthimion,Erik P. Gilson,Larry R. Grisham,Igor Kaganovich,Hong Qin,Adam B Sefkow,Edward A. Startsev,Dale Welch,Craig L. Olson +32 more
TL;DR: In this article, the authors assess how these new techniques might apply to heavy ion fusion drivers for inertial fusion energy, and assess the feasibility of using them to accelerate ion-beam-driven warm dense matter.
