The application of an external 26 Tesla axial magnetic field to a D2 gas-filled capsule indirectly driven on the National Ignition Facility is observed increase ion temperature by 40% and neutron yield factor 3.2 in hot spot with areal density approaching what required for fusion ignition [1]. improvements are determined from energy spectral measurements 2.45 MeV neutrons D(d,n)3He reaction, compressed central core B estimated be ∼4.9 kT using 14.1 secondary D(T,n)4He reactions. experiments...
Application of a magnetic field to an indirect drive inertial confinement fusion target requires diffusion the through high-Z and electrically conducting Hohlraum. The onset external generates eddy currents in Hohlraum wall that result (1) reduction peak at capsule, (2) heating Ohmic dissipation, (3) movement due inward force from current interacting with field. Heating causes increase blackbody radiation which can preheat capsule frozen deuterium–tritium fuel, while motion leads potential...
Magnetizing a cryogenic deuterium–tritium (DT)-layered inertial confinement fusion (ICF) implosion can improve performance by reducing thermal conduction and improving DT-alpha in the hot spot. A room-temperature, magnetized indirect-drive ICF platform at National Ignition Facility has been developed, using high-Z, high-resistivity AuTa4 alloy as hohlraum wall material. Experiments show 2.5× increase deuterium–deuterium (DD) neutron yield 0.8-keV hot-spot temperature with application of 12-T...

Abstract The Mochi device is a new pulsed power plasma experiment designed to produce long, collimated, stable, magnetized jets when set up in the LabJet configuration. configuration aims simulate an astrophysical jet laboratory by mimicking accretion disk threaded poloidal magnetic field with concentric planar electrodes front of solenoidal coil. unique setup consists three electrodes, each azimuthally symmetric gas slits. Two are biased independently respect third electrode control radial...
Implantations of degradable biomaterials for drug delivery or restoration and regenerative medicine cause fibrosis acute inflammation which may lead to chronic side effects. Additionally, the fibrous encapsulation can itself inhibit local cells from proliferating forming new healthy tissue. Current models require a method decrease adverse effects following implantation in patients activation signaling sent quiescent fibroblasts. This research details novel chemical physical properties...
The National Ignition Facility (NIF), the world's most energetic laser, focuses 192 laser beams onto a pea-sized target inside 10-meter diameter chamber. While relying on its three major pulsed power systems to generate more than 1.8 MJ of UV light, NIF benefits from several other applications, ranging low front end diagnostics for broad spectrum physics experiments. In this paper, we will discuss our recent development efforts and provide projection into future projects, including...
