Design of Instrumentation and Methodologies for Determination of Free Neutron Characteristics
(University of Missouri -- Kansas City, 2017)
Measuring neutron source‐dependent free neutron properties over a large neutron energy range, with human‐portable instrumentation, continues to push the frontier of neutron detection instrumentation design and analysis ...
Photoemission Spectroscopy Studies of New Topological Insulator Materials
(2015-08-04)
As the size of a solid shrinks, the ratio of surface area to bulk volume grows and
surface effects become more important. In a world where technologies advance with the
shrinking size of electronic devices, one phase of ...
Uranium Oxides for Solid-State Direct-Conversion Neutron Detection
(2020)
to achieve absorption probabilities of a few percentages: 1.5–4% for 10 MeV neutrons for natural uranium oxides, ∼2% for 1 MeV neutrons for ²³⁵U-based uranium oxides, and 7–9% for thermal neutrons for natural uranium oxides, assuming each detector is 1 cm...
Amorphous hydrogenated boron carbide for solid-state direct-conversion thermal neutron detection
(2021)
have investigated the effect of single-carrier transport and low charge carrier mobility, which are expected in a-BC:H films, on detection efficiency and spectral performance of a thin-film B4C detector using numerical Monte Carlo calculations...
RF coupling to realistic wire systems in complex environments
(2021)
With the continuous emergence of new wireless technologies, the possibility of unintentional electromagnetic interference (EMI) increases significantly. EMI coupling pathways to any Device Under Test (DUT) can be classified ...
Frequency and Field Strength Materials Characterization with Complementary Split-ring Resonators, Coplanar Waveguides, and the Virtual Ground Method
(University of Missouri -- Kansas City, 2019)
In the radiofrequency bands, measuring the power-dependent complex permittivity
and permeability of materials that undergo metal–insulator transitions is a significant
challenge which is important for defense and ...
Neutron Response Vectorization and Optimization of Moderating Neutron Spectrometers for Active Interrogation
(University of Missouri–Kansas City, 2015)
The detection of special nuclear material (SNM) is no trivial task; the low activity of isotopes such as 235U and the ease of shielding make their passive detection virtually impossible in the maritime environment. Active ...
