Summary form only given. We have installed the National Ignition Facility Neutron Imaging System. The imaging system provides information about the areal density of fuel in the various regions of the capsule implosion. A long line of sight enables imaging both the primary 14 MeV neutrons as well as the down-scattered neutrons with energies in the range of 9-12 MeV. The imager is a pinhole camera w...Show More
Summary form only given. The neutron imaging diagnostic has recently been commissioned at the National Ignition Facility. We will present the diagnostic performance characteristics, which have been measured with the collection of these first neutron images. The goal for this diagnostic is to collect two pinhole images at two different times. The long flight path results in a chromatic separation o...Show More
Summary form only given, as follows. Inertial electrostatic confinement (IEC) devices have demonstrated significant neutron yields (as high as 2/spl times/10/sup 10/ neutrons/second, steady state) in a compact and inexpensive scale. Recent technological progress in plasma sources, vacuum technology and high voltage materials indicates that an order of magnitude increase in neutron yield may be ach...Show More
Summary form only given. Plasmas become strongly coupled (SCP) when the coulomb interaction energy between particles is comparable or greater than the thermal kinetic energy. This occurs at low temperatures (T/spl sim/1 eV) and high densities (n/sub c//spl sim/10/sup 21/ cm/sup -3/). SCPs are found in the interior of gas planets and white dwarf stars, as well as in high energy density physics expe...Show More
Summary form only given. Atlas is a high current (/spl sim/30 MA peak, with a current risetime /spl sim/4.5 /spl mu/sec), high energy (E/sub stored/=24 MJ, E/sub load/=3-6 MJ), pulsed power facility which is being constructed at Los Alamos National Laboratory with a scheduled completion date in the year 2000. When operational, this facility will provide a platform for experiments in high pressure ...Show More
Summary form only given, as follows. Atlas is a high-energy pulsed-power facility under development at Los Alamos National Laboratory to drive high-energy density experiments. It is optimized for materials properties and hydrodynamics experiments under extreme conditions. The system is designed to implode heavy liner loads with a peak current of 30-40 MA delivered in /spl sim/4 /spl mu/s. Atlas wi...Show More
Summary form only given. We are investigating experimentally the effects of sheath overlap during plasma source ion implantation of a large workpiece of complex geometry. The workpiece consists of 1000 aluminum, automotive piston surrogates mounted on 4 racks; total surface area is over 16 m/sup 2/. The 4 racks are positioned parallel to each other, 0.25 m apart, in an 8 m/sup 3/ vacuum chamber. T...Show More
Summary form only given. The United States Department of Energy complex has a significant legacy of equipment which has been used in the production of the nations nuclear weapons stockpile, and is consequently contaminated with Transuranic (TRU) material. Portions of this equipment set (glove boxes, ventilation ducts, large pipes, etc.) consist of relatively large, often geometrically complex item...Show More
