The los alamos national laboratory neutron-neutron scattering program

Performance of the Los Alamos National Laboratory spallation-driven solid-deuterium ultra-cold neutron source.

In this paper, we describe the performance of the Los Alamos spallation-driven solid-deuterium ultra-cold neutron (UCN) source. Measurements of the cold neutron flux, the very low energy neutron production rate, and the UCN rates and density at the exit from the biological shield are presented and compared to Monte Carlo predictions. The cold neutron rates compare well with predictions from the...

EA-1131; Environmental Assessment of the Relocation of Neutron Tube Target Loading Operations Los Alamos Laboratory Los Alamos, New Mexico

Waste Burial Site, Los Alamos National Laboratory

Small mammals were sampled at two waste burial sites (Sites 1 and 2) at Area G, TA-54, and a control site outside Area G (Site 3) to identify radionuclides that are present within surface and subsurface soils at waste burial sites, to compare the amount of radionuclide uptake by small mammals at waste burial sites to a control site, and to identify the primary mode of contamination to small mam...

arXiv.org: the Los Alamos National Laboratory e-print server

Since its creation nearly ten years ago, the Los Alamos National Laboratory (LANL) e-print service (arXiv.org) has revolutionized scholarly communication within many scientific communities. It has also inspired the development of alternatives to conventional and electronic journal publication in a variety of other disciplines. The LANL e-print database is also serving as the core collection for...

Validation of Structural Dynamics Models at Los Alamos National Laboratory

This publication proposes a discussion of the general problem of validating numerical models for nonlinear, transient dynamics. The predictive quality of a numerical model is generally assessed by comparing the computed response to test data. If the correlation is not satisfactory, an inverse problem must be formulated and solved to identify the sources of discrepancy between test and analysis ...
