Characteristics of light charged particle emission in spontaneous and neutron induced fission of Cm and Cf isotopes
… fragments are accompanied by a light charged particle. Ternary fission data are of interest for nuclear physics, however also the nuclear industry requests accurate data for ternary fission yields, especially 3H and 4He, since they are at the origin of the production of He gas and the …

Beta-delayed proton emission of magnesium-20 and the RCMP silicon detector array
… state. The goal was to investigate delayed particle emission for isotopes near proton drip line. The main secondary beam was ²²Si while other exotic beam such as ²⁰Mg,²²Al,²³Si was also produced. The delayed particle emission from ²⁰Mg is of particular interest in this thesis and has been …

Combustion of fine magnesium particles
… prompted studies of combustion mechanisms for particles of such alloys with different Al/Mg ratios. Reference experiments with pure Al and Mg powders are also desired to better understand and model combustion of the respective alloys. While combustion of pure Al powders has been addressed in …

Finite kinematics in radiative energy loss
We investigate the behaviour of particle emission spectra in the largex region derived from a rigorous implementation of the exact kinematic constraints in the framework of a scalar model of radiative emissions. We find that the small-x kinematic constraints in the simpler theory are identical to …

Modeling Size-Resolved Particle Number Emissions From Advanced Technology And Alternative Fueled Vehicles In Real-Operating Conditions
Two particle number emission datasets were analyzed in detail. The first data set contained particle number emissions from four transit buses, including two hybrid diesel-electric buses, under a variety of driving conditions and technological/fuel treatments including: diesel oxidation catalysts, …

Performance of metallic and carbon based materials under the influence of intense transient energy deposition
… associated with evaporation and liquid or solid particles emission are also serious issues to influence plasma contamination. In order to estimate the lifetime of the components during above mentioned events (ELMs, disruptions, VDEs), the thermal erosion mechanisms and performance of carbon-based …

Two-Particle Correlations at 40, 80, and 158 AGeV Pb-Au Collisions
… this thesis, a centrality dependent study of tow-particle momentum correlations of like-sign pions (HBT interferometry) from Pb-Au collisions at beam energies of 40, 80 and 158 AGeV is presented. The three-dimensional correlation function C_2, depending on the relative momentum components of the …

Measurements that fill gaps in emission inventories: gas flares, household biomass stoves, and brick kilns
… purpose of this body of work is to fill gaps in emission inventories that in turn serve as inputs to global climate models. Emissions of aerosols are a focus because they can vary by orders of magnitude even for the same fuel, making field emissions measurements necessary. Three sources were …

Observation and study of giga electron volt solar energetic particles using the Milagrito extensive air shower detector
<p>Measurements of high energy emission from solar events can lead to an understanding of the solar energetic particle acceleration mechanism(s). Although the energy source of these mechanisms is known to reside in the solar magnetic field, the details of the acceleration process(es) have continued …
