A standard fast reactor spectrum can be created by the partial moderation of the U-235 fission spectrum in an air cavity. Spherical natural uranium shells are driven by thermal neutrons from a thermal column. The uranium is placed at the center of a spherical graphite hohlraum to reduce the anisotropic...
A system to perform neutron radiographic analysis of dynamic
events taking place over the order of several milliseconds has been
developed at Oregon State University. The design consists of a TRIGA
reactor capable of pulsing to 3000 MW peak power, a neutron beam
collimator with an L/D of about 30:1,...
Narrow angle light scattering measurements were made for various sizes of spherical particles suspended in water. These were compared to calculated theoretical scattering values as derived from the theory of Mie (1908). Through measurements with different particle concentrations at angles between 0.2° and 0.7° the effect of the unscattered main...
During May and September of 1978, cruises were made in Monterey Bay
to study the relationship of ocean color spectra measured by aircraft and
in situ optical, hydrographic, and chemical parameters. These cruises were
carried out by the Oregon State University optical oceanography group and
by the Naval Postgraduate School...
Hydrographic and optical measurements were made in situ in the Congo River and the Angola Basin during May 1978. These measurements were made by members of the optical oceanography group at Oregon State University in cooperation with scientists from the Netherlands Institute for Sea Research. The data taken by the...
Measurements of total irradiance versus depth and beam transmission versus depth were made at
stations near shore along the west coast of the North and South American continents. The water types at
each station were optically classified according to the system of Jerlov (1976), thus providing additional
information for the...
Spectral beam attenuation coefficients, spectral volume scattering
function meaurements at 45°, 90°, and 130° particle size distributions
and chlorophyll a and phaeophytin pigment concentrations were measured during
May and September, 1977 in Monterey Bay, California. This data is examined
and statistical interrelationships between the parameters measured are
explored.
It was...
The solar energy flux as a function of depth (the irradiance profile) in the ocean is an important function. It influences the dynamics of the mixed layer via the heat budget as well as the biology of the euphotic zone. The following three-parameter model can take into account the very...
