Journal ArticleDOI
Characterization of fusion burn time in exploding deuterium cluster plasmas
J. Zweiback,Thomas E. Cowan,Roland Smith,J. H. Hartley,Richard H. Howell,C. A. Steinke,G. Hays,Ken Wharton,John K. Crane,Todd Ditmire +9 more
TL;DR: High-resolution neutron time-of-flight spectroscopy on deuterium clusters shows that they yield fast bursts of nearly monochromatic fusion neutrons with temporal duration as short as a few hundred picoseconds, opening up the unique possibility of using these bright neutron pulses, either as a pump or a probe, to conduct ultrafast studies with neutrons.
Journal ArticleDOI
High-order harmonic emission from mixed fields
Michael D. Perry,John K. Crane +1 more
TL;DR: By controlling the relative polarization of the two fields, this work can control the mixing efficiency and produce coherent extreme ultraviolet (XUV) radiation polarized orthogonally to the strong driving field.
Journal ArticleDOI
An overview of LLNL high-energy short-pulse technology for advanced radiography of laser fusion experiments

Payne,Deanna Marie Pennington,L. Risinger,Michael C. Rushford,Kenneth M. Skulina,Mary L. Spaeth,Brent C. Stuart,G. L. Tietbohl,Benoit Wattellier +35 more
TL;DR: In this article, the technical challenges and motivations for high-energy short-pulse generation with the National Ignition Facility (NIF) and possibly other large-scale Nd : glass lasers are reviewed.
Journal ArticleDOI
Space-charge effects in high brightness electron beam emittance measurements
TL;DR: In this article, the role of space charge forces in a traditional measurement of transverse emittance, the quadrupole scan, is discussed and the mitigation of these effects by use of multislit-or pepperpot-based techniques is explained.
Journal ArticleDOI
Detailed study of nuclear fusion from femtosecond laser-driven explosions of deuterium clusters
J. Zweiback,Thomas E. Cowan,J. H. Hartley,Richard H. Howell,Ken Wharton,John K. Crane,Victor Yanovsky,G. Hays,Roland Smith,Todd Ditmire +9 more
TL;DR: In this article, a 35 fs laser pulse was used to irradiate deuterium clusters with van der Waals bonded clusters, and it was found that the fusion neutron yield is strongly dependent on such factors as cluster size, laser focal geometry, and gas jet parameters.
