PXAMS -- Projectile X ray AMS: X ray yields and applications

Description: Characteristic x rays have recently been explored as a method for the detection and identification of ions in accelerator mass spectrometry (AMS). After analysis in the AMS spectrometer, the ions stop in an appropriately chosen target and the induced x rays identify the ions by atomic number. For the application of AMS to higher mass isotopes, characteristic x rays allow significantly better discrimination of competing atomic isobars than is possible using energy loss detectors. Characteristic … more

Spool assembly support analysis

Description: This document provides the wind/seismic analysis and evaluation for the pump pit spool assemblies. Hand calculations were used for the analysis. UBC, AISC, and load factors were used in this evaluation. The results show that the actual loads are under the allowable loads and all requirements are met.

Aerogel commercialization: Technology, markets and costs

Description: Commercialization of aerogels has been slow due to several factors including cost and manufacturability issues. The technology itself is well enough developed as a result of work over the past decade by an international-community of researchers. Several extensive substantial markets appear to exist for aerogels as thermal and sound insulators, if production costs can keep prices in line with competing established materials. The authors discuss here the elements which they have identified as key… more

Dose Contribution from High Level Waste Uranium and Plutonium. Revision 1

Description: Radiological source terms for safety analyses traditionally have been curie lists of radionuclides. Converting the source term to dose values allows each radionuclide to be evaluated for its impact on dose, which is the purpose of the source term. This report is one in a series of reports establishing source terms for High Level Waste (HLW) by evaluating the dose impact of each radionuclide. These reports will be used in establishing the source terms to be used in HLW Safety Analysis Reports. T… more

Polarization and N-N elastic scattering amplitudes

Description: We discuss the role of polarization measurements and scattering amplitudes for elastic nucleon-nucleon processes at high energy. The relative normalization of these amplitudes involves a ``leading order form factor`` which we determine empirically. These amplitudes provide an economical description of a large body of existing data and make some nontrivial predictions for spin observables. In particular, we have investigated cross sections and asymmetry data at large angles (including 90{degrees… more

Optimizing the length of the stores and related effects

Description: This memo is an attempt to create an accurate analytical model for the luminosity obtained in the Fermilab Tevatron during collider operation. Other people, in particular Alan Hahn and, aledgedly, Vinod Bharadwaj and Gerry Dugan, have addressed this topic and predicted an optimum store duration. The approach taken here is slightly different from Hahn`s, in particular, analytic forms for the model are written down and the optima are found directly, through differentiation. Also, specifying the p… more

In situ sampling device development engineering task plan

Description: This engineering task plan (ETP) supports the development for facility use of an improved packaging method or device for the sorbent media used during in situ sampling of waste tanks. Improvement is being sought due to problems with internal and external radioactive contamination. In situ sampling refers to placing sample collection media (primarily sorbent tubes) directly into the tank headspace, then drawing tank gases through the collection media to obtain samples. Development for facility u… more

High power ultrashort pulse lasers

Description: Small scale terawatt and soon even petawatt (1000 terawatt) class laser systems are made possible by application of the chirped-pulse amplification technique to solid-state lasers combined with the availability of broad bandwidth materials. These lasers make possible a new class of high gradient accelerators based on the large electric fields associated with intense laser-plasma interactions or from the intense laser field directly. Here, we concentrate on the laser technology to produce these … more

Integrated assessment and the relation between land-use change and climate change

Description: Integrated assessment is an approach that is useful in evaluating the consequences of global climate change. Understanding the consequences requires knowledge of the relationship between land-use change and climate change. Methodologies for assessing the contribution of land-use change to atmospheric CO{sub 2} concentrations are considered with reference to a particular case study area: south and southeast Asia. The use of models to evaluate the consequences of climate change on forests must al… more
