Most published material on the popular high power soft-switched full bridge phase-shift converter has focused on its use in telecommunications and similar power supply applications. In such service the load tends to be resistive and nonfluctuating in nature, so published literature, with one notable exception has not probed the behavior of the topology(More)
Plutonium (Pu) dioxide particles were produced from certified reference material (CRM) 136 solution (CRM 136-plutonium isotopic standard, New Brunswick Laboratory, Argonne, IL, U.S.A., 1987) using an atomizer system on December 3, 2009 after chemical separation of americium (Am) on October 27, 2009. The highest density of the size distribution of the(More)
Physical, chemical, and isotopic analyses of individual radioactive and other particles in the micron-size range, key tools in environmental research and in nuclear forensics, require the ability to precisely relocate particles of interest (POIs) in the secondary ion mass spectrometer (SIMS) or in another instrument, after having been located, identified,(More)
