Considerations for an active and passive scanner to assay nuclear waste drums

Description: Radioactive wastes are generated at many DOE laboratories, military facilities, fuel fabrication and enrichment plants, reactors, hospitals, and university research facilities. At all of these sites, wastes must be separated, packaged, categorized, and packed into some sort of container--usually 208-L (55-gal) drums--for shipment to waste-storage sites. Prior to shipment, the containers must be labeled, assayed, and certified; the assay value determines the ultimate disposition of the waste con… more

A 3D Particle Simulation Code for Heavy Ion Fusion Accelerator Studies

Description: We describe WARP, a new particle-in-cell code being developed and optimized for ion beam studies in true geometry. We seek to model transport around bends, axial compression with strong focusing, multiple beamlet interaction, and other inherently 3d processes that affect emittance growth. Constraints imposed by memory and running time are severe. Thus, we employ only two 3d field arrays ({rho} and {phi}), and difference {phi} directly on each particle to get E, rather than interpolating E from … more

Development of deep drawn aluminum piston tanks

Description: An aluminum piston tank has been developed for applications requiring lightweight, low cost, low pressure, positive-expulsion liquid storage. The 3 liter (183 in{sup 3}) vessel is made primarily from aluminum sheet, using production forming and joining operations. The development process relied mainly on pressurizing prototype parts and assemblies to failure, as the primary source of decision making information for driving the tank design toward its optimum minimum-mass configuration. Critical … more

A quark-gluon plasma search in anti p --p at radical s = 1. 8 TeV

Description: The search by E-735 for QGP evidence in centrally produced particles in {bar p}p collisions has revealed several interesting results in the behavior with variation of dN{sub c}/d{eta} in the measured interval from 2--18. In {l angle}P{sub t}{r angle} we see a decrease in slope for all particles near dN{sub c}/d{eta} {approx equal} 9 corresponding to a Bjorken initial energy density of 2.2 GeV/{sub fm}{sup 3}. Above dN{sub c}/d{eta} = 10, the increase of {l angle}P{sub t}{r angle} is small excep… more
