Recent experiments on the interaction of intense, ultrafast pulses with large van der Waals bonded clusters have shown that these clusters can explode with sufficient kinetic energy to drive nuclear fusion. Irradiating deuterium clusters with a 35 fs laser pulse, it is found that the fusion neutron yield is strongly dependent on such factors as cluster size, laser focal geometry, and deuterium ...
Detector Crystal The Laser Fusion Experiments Groups from the Laboratory for Laser Energetics (LLE) and the Los Alamos National Laboratory (LANL) have jointly developed an instrument capable of simultaneously space-, time-, and spectrally resolving x-ray emission from inertial confinement fusion (ICF) targets. Uses of the instrument include framed imaging of line emission from fuel or shell dop...
230 LLE Review, Volume 96 Introduction In an inertial confinement fusion (ICF)1 experiment, a capsule filled with deuterium (D2) or a deuteriumtritium (DT) fuel is heated by either direct laser illumination or soft-x-ray radiation in a laser-heated hohlraum. The target is compressed to conditions under which thermonuclear fusion occurs. The fusion burn begins with spark ignition of the central...
As the basic conditions for laser inertial confinement fusion (ICF) research, the targets are required to be well specified and elaborately fabricated. Because of the characteristics of the targets, the research and fabrication process is a systematically tough task, which needs fundamental and deep insights into film deposition, mechanical machining, precise measurement and assembly, etc. As a...
We demonstrate the hohlraum radiation temperature and symmetry required for ignition-scale inertial confinement fusion capsule implosions. Cryogenic gas-filled hohlraums with 2.2 mm-diameter capsules are heated with unprecedented laser energies of 1.2 MJ delivered by 192 ultraviolet laser beams on the National Ignition Facility. Laser backscatter measurements show that these hohlraums absorb 87...
Recently NAano-Plasmonic, Laser Inertial Fusion Experiments (NAPLIFE) were proposed, as an improved way to achieve laser driven fusion. The improvement is the combination of two basic research discoveries: (i) possibility detonations on space-time hyper-surfaces with time-like normal (i.e. simultaneous detonation in a whole volume) and (ii) increase this volume target, by regulating light absor...
Robot map navigation and localization are challenges that, if they are to be overcome, require the solving of the data association problem for local and global features. Data fusion approaches allow highlight the advantages of two or more sensors, and complementary cooperation can be obtained. This paper presents two methods to embed depth information in omnidirectional images using the extrins...
For the investigation of the completely unknown atomic level structure of the element nobelium a novel experimental procedure has been developed. It is based on Radiation Detected Resonance Ionization Spectroscopy (RADRIS) which had to be improved and modified to accommodate the prerequisites at SHIP. It can be applied to elements like nobelium produced at rates of a few ions per second. The io...
Quantitative measurements of the x-ray emission from laser-produced plasmas have been a subject of considerable interest since the early 1970s.l With the fabrication of large, in some cases multibeam, highpower laser systems, much work has been performed on the analysis of x-ray emission from laser-produced plasmas of high-atomic-number materiak2 Measurements of soft x-ray emission from the pla...
