Total reflection X-ray fluorescence analysis (TXRF) of light elements, such as C, O and Al (atomic numbers 5–13) generally has poor sensitivity and detection limits due to poor excitation and low fluorescent yields. Special excitation sources are n

Synchrotron radiation from SSRL (Stanford Synchrotron Radiation Laboratory) Beam Line III-4 was used as excitation source for Total Reflection X-ray Fluorescence Analysis (TXRF) of light elements (Z < 14). Due to the outstanding features of synchrotr

Characterization of mixed wastes (that is, radioactive and otherwise hazardous) requires that all hazardous, non-conforming, and radioactive materials be identified, localized, and quantified. With such information, decisions can be made regarding wh

We have investigated three small explosive parts for the Pantex Plant in Amarillo, Texas using computed tomography (CT). A medium resolution, fan beam system was used to test imaging capabilities for small holes drilled into one of the parts, and to

Monochromatization combining total reflection by a selected mirror and an appropriate filter offered an alternative approach in order to increase measurable intensity with reasonable spectral resolution. Recently, the use of synthetic multilayers, wh

The Lawrence Livermore Laboratory brine treatment test system has been used to carry out a short-term evaluation of a number of proprietary chemical additives as antiscalants for the hypersaline brine of the Salton Sea Geothermal Field. In addition,

A non-destructive method is described for the quantitative measurement of impurities in KDP (KH/sub 2/PO/sub 4/) crystals. Part per million concentrations of impurities can be determined with good accuracy in about one hour of instrument time. An ene

Factors affecting the precipitation of solids and deposition of scale from the hypersaline brines of the Salton Sea geothermal field - two potential problems in the proposed utilization of these brines for electric power generation - were investigate
