    Gas Cherenkov detector (GCD)

    LLE and LANL collaborated on the development of a new gas Cherenkov detector (GCD-3) for gamma-ray spectroscopy on OMEGA. OMEGA experimental system technician (EST) Dan Neyland is shown with the GCD-3 (nearest Dan) and an earlier instrument (GCD-2) on the OMEGA target chamber platform.

    Isotope Separation System

    LLE's new Isotope Separation System will provide a flexible tritium fuel supply and ensure that the purity of that fuel supply meets LLE's inertial confinement fusion program requirements.

    25,000th shot on OMEGA

    In 2014, the Omega Laser Facility conducted its 25,000th target shot for experiments designed to create and study extreme states of matter. Shown in the large photo above is the interior of the OMEGA target chamber during one of the target shots. The insets illustrate some of the targets routinely used for the OMEGA experiments.

    DRACO

    The DRACO multidimensional hydrocode is routinely used by LLE scientists to model and design target implosions. DRACO plots show the density [ρ(g/cm3)] distributions at maximum compression from simulations of implosion targets illuminated by different-sized laser beams: beam radius/target radius = 1.07, 0.8, and 0.7.

    Rebuilt MIFEDS

    A 10-mm-diam MIFEDS (magneto-inertial fusion electrical discharge system) magnetic coil comprised of Kapton-insulated copper wire wound around a 3-D printed plastic coilform. Larry Folnsbee (LLE engineer) is assembling MIFEDS.

    AstroBEAR

    A sequence of images showing "triggered star formation," where a shock wave from a nearby supernova sweeps across a cloud of interstellar gas. The simulation was carried out with the parallel adaptive mesh refinement magnetohydrodynamic multiphysics code AstroBEAR, developed by the University of Rochester's computational astrophysics group led by Prof. Adam Frank, in collaboration with (and support from) LLE.

    Strong-shock experiment

    OMEGA experiments generated strong shocks in solid sphere targets with peak ablation pressures exceeding 300 Mbar. The x-ray framing camera images show the early coronal x-ray emission from the target surface during the laser interaction and, later, the x-ray flash from the target center generated from the converged shock wave

    NIF polar drive

    LLE scientist Matthias Hohenberger discussing a just-completed NIF (National Ignition Facility) polar-drive implosion. Matthias is stationed at Lawrence Livermore National Laboratory and is the Principal Investigator for the LLE polar-drive campaign on the NIF. The data is being used to validate modeling of ignition-scale, direct-drive implosions in anticipation of a polar-drive–ignition campaign by the end of the decade.
