Simulations of ion distributions
// Journal Covers
We describe fully self-consistent time-dependent simulations of radio frequency (RF) generated ion distributions in the ion cyclotron range of frequencies and RF-generated electron distributions in the lower hybrid range of frequencies using combined Fokker–Planck and full wave electromagnetic field solvers.
Computed temperature field inside the target
// Journal Covers
A detailed computation of the temperature profile for liquid hydrogen inside a hollow shell, as is found in inertial confinement fusion research, shows that seeds are likely to form at the equatorial plane of the shell.
Temperature simulations
// Journal Covers
Experiments on the Titan laser at the Lawrence Livermore National Laboratory were carried out in order to study the properties of fast electrons produced by high-intensity, short pulse laser interacting with matter under conditions relevant to fast ignition.
Product of the deuterium and tritium number densities in simulation
// Journal Covers
Presents the first results from an experimental campaign to measure the atomic ablator-gas mix in the deceleration phase of gas-filled capsule implosions on the National Ignition Facility.
Marine organisms
// Journal Covers
Research team analyzes records of bulk and amino-acid-specific 15N/14N isotopic ratios (δ15N) preserved in the skeletons of long-lived deep-sea proteinaceous corals collected from the Hawaiian archipelago; these isotopic records serve as a proxy for the source of nitrogen-supported export production through time.

Research shows that the interaction of relativistic-intensity, picosecond laser pulses with solid targets is affected by the reflected light through the strong currents and 104  T magnetic fields it produces.
Molecular model
// Journal Covers
This paper reports observations of shock compressed, unreacted hydrogen peroxide at pressures up to the von Neumann pressure for a steady detonation wave, using ultrafast laser-driven shock wave methods.
Graphic of waveguide
// Journal Covers
A new generation of hollow waveguide (HWG) gas cells of unprecedented compact dimensions facilitating low sample volumes suitable for broad- and narrow-band mid-infrared (MIR; 2.5–20 μm) sensing applications is reported: the substrate-integrated hollow waveguide (iHWG).
Plasma images and data
// Journal Covers
We report a study of materials recovered from a uranium-containing plasma generated by an electric arc.
