Development of a High-Energy Neutron Sniffer and Subsequence Dose Quantification for High-Energy Particle Accelerator Shielding Surveys

Creator:: Overbay, Lauren A.
Abstract:: The objective of this research is to design a portable neutron detector that is lightweight and responds to neutrons with energies of 20 MeV and greater. The instrument will be used as a ‘sniffer’ probe for identifying shielding weaknesses at high-energy particle accelerators and be paired with a plastic scintillator...

Theoretical-experimental neutron spectrum comparisons by an orthonormal series expansion method

Creator:: Skeen, David Roy
Abstract:: This thesis presents and discusses a method for comparing the neutron flux of some calculational model with the actual flux of a critical system. Both the theoretical and experimental aspects of this method are investigated in this report. Experiments were performed to find neutron energy dependent data. These involved the...

Construction and calibration of a fast neutron spectrum generator

Creator:: Dobbin, Kenneth Dwight
Abstract:: 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...

Feasibility of neutron radiographing reactor fuel assemblies

Creator:: Oien, C. T. (Charles T.)
Abstract:: Verification of fast reactor safety requires experiments wherein fuel bundles, enclosed in massive steel capsules, are subjected to simulated accident conditions in reactors such as TREAT(16) at ANL Idaho. To date, only small bundles (one to seven pins) have been tested in the experimental series. Determination of the fuel configuration...

High speed motion neutron radiography of two-phase flow

Creator:: Wang, Shou-Kong Lancelot
Abstract:: Current research in the area of two-phase flow utilizes a wide variety of sensing devices, but some limitations exist on the information which can be obtained. Neutron radiography is a feasible alternative to "see" the two-phase flow. A system to perform neutron radiographic analysis of dynamic events which occur on...

Application of high speed motion neutron radiography techniques to liquid streams injected into a pressurized steel chamber

Creator:: Tollefson, Dennis A.
Abstract:: A high speed motion neutron radiography system has been developed at Oregon State University which is capable of taking high speed neutron radiographs of events which occur on the order of one to two milliseconds or more. This system was used previously to demonstrate the application of high speed motion...

Optimum temporal and contrast considerations in extremely high speed motion neutron radiography

Creator:: Greek, Kevin J.
Abstract:: A facility developed using the OSU TRIGA pulsing capability and high speed motion photography has been used successfully for more than a decade to produce dynamic neutron radiographs of solid propellant combustion, two phase flow, and liquid streamflow. The existing imaging components have undergone little modification since the experiment's inception...

Real-time neutron radiography

Creator:: Newell, Daniel L.
Abstract:: A real-time neutron radiography system has been developed at Oregon State University which is capable of producing neutron radiographs of objects and events concurrent with the incident radiation. The purpose of this thesis is to demonstrate the feasibility of the real-time technique as a further application of neutron radiography at...

Neutron radiography and tomography : determining and optimizing resolution of neutron sensitive multi channel plate detectors

Creator:: Williams, Walter James
Abstract:: The objective of this work was to determine and optimize the resolution of a neutron sensitive Multi-Channel Plate (MCP) detector in order to determine its capabilities in radiography and tomography. The Oregon State University, Neutron Radiography Facility added an MCP Detector in 2012 in order to analyze these capabilities. The...
