Characterization of Lithium Aluminate Powders

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Bradley Johnson
Project type
Exploratory Research
Enriched lithium aluminate powders have been commercially produced for high-yield, high-through-put, dry press preparation of low temperature sintered pellets. These pellets are used for the tritium…

Amorphous Semiconductor Analysis using Ion Beam Tools

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Charles Henager
Project type
Large-Scale EMSL Research
The goal of this proposal is to develop new materials for high resolution, room temperature gamma radiation detection. We propose to develop high Z, high resistivity, amorphous, semiconductors to be…

Microsampling Isotope Ratio Mass Spectrometer Development

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Helen Kreuzer
Project type
Exploratory Research
We are using a combination of laser ablation, catalytic reactor technology, and systems engineering to develop a novel device that converts the O and H in solid organic samples to CO and H2,…

Chalcogenide Surface Science

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Bradley Johnson
Project type
Limited Scope
The objective of this work is to use XPS to study the surface chemistry of IR transparent chalcogenide fibers that have undergone photo-induced and/or opto-mechanical failures. Raytheon Missile…

Chalcogenide Surface Science

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Bradley Johnson
Project type
Exploratory Research
Chalcogenide nanowires have been observed to form on soda lime glass and fused quartz substrates. These materials have potential application for analytical and photonic devices. Further research is…
