Prior Experience and Past Performance as Evaluation Criteria in the Award of Federal Construction Contracts

Description: A publication issued by the Government Accountability Office with an abstract that begins "Over the last 10 fiscal years, federal agencies have increased their spending on construction contracts, leading to obligations of almost $54 billion in fiscal year 2010. When awarding contracts, the Federal Acquisition Regulation (FAR) requires agencies to consider firms' performance records to help ensure that taxpayer dollars go to capable contractors. The FAR also provides agencies with broad discreti… more

Matlab Based LOCO

Description: The LOCO algorithm has been used by many accelerators around the world. Although the uses for LOCO vary, the most common use has been to find calibration errors and correct the optics functions. The light source community in particular has made extensive use of the LOCO algorithms to tightly control the beta function and coupling. Maintaining high quality beam parameters requires constant attention so a relatively large effort was put into software development for the LOCO application. The LOCO… more

Neutron-capture Cross Sections from Indirect Measurements

Description: Cross sections for compound-nuclear reactions play an important role in models of astrophysical environments and simulations of the nuclear fuel cycle. Providing reliable cross section data remains a formidable task, and direct measurements have to be complemented by theoretical predictions and indirect methods. The surrogate nuclear reactions method provides an indirect approach for determining cross sections for reactions on unstable isotopes, which are difficult or impossible to measure othe… more

Pre-shot simulations of far-field ground motion for the Source Physics Experiment (SPE) Explosions at the Climax Stock, Nevada National Security Site: SPE2

Description: The Source Physics Experiment (SPE) is planning a 1000 kg (TNT equivalent) shot (SPE2) at the Nevada National Security Site (NNSS) in a granite borehole at a depth (canister centroid) of 45 meters. This shot follows an earlier shot of 100 kg in the same borehole at a depth 60 m. Surrounding the shotpoint is an extensive array of seismic sensors arrayed in 5 radial lines extending out 2 km to the north and east and approximately 10-15 to the south and west. Prior to SPE1, simulations using a fin… more
