Modeling of interferences in gamma ray pulse height distributions

Creator:: Harris, Richard D. (Richard Donald), 1961-
Abstract:: The purpose of this study was to develop a model to calculate gamma ray pulse height distributions that closely approximate measured ones. The model was used to produce a pulse height distribution for a postaccident coolant sample from a nuclear reactor. Lower limits of detection were calculated for certain key...

Use of BC-523a liquid scintillator for simultaneous neutron spectroscopy and gamma counting with the implementation of a neutron history reconstruction algorithm

Creator:: Frey, Wesley D.
Abstract:: Real-time, high efficiency neutron spectroscopy has, historically, been a persistent challenge in the field of radiation detection and, for the most part, has gone unsolved. The most promising method to resolve this challenge, is the boron-capture technique using an organic scintillation system (BC-523a). Detectors that utilize this method possess an...

Deriving relationships between number of observed short gamma ray bursts and viewing angle

Creator:: Micallef, John T.
Abstract:: Gamma ray bursts are some of the brightest events in the entire observable universe. Since the late 1960’s, thousands of gamma ray bursts have been observed and they have been researched extensively. However, there are still many mysteries which remain unsolved. One such mystery is whether or not the viewing...

Computational Modeling of Photon Scattering In Gamma Ray Bursts Using Monte Carlo Techniques

Creator:: Nguyen, Bao
Abstract:: The current model for gamma ray bursts (GRBs) assumes that internal shocks are responsible for the emission of gamma-rays. Internal shocks occur when the fast expanding shell collides with the slowly expanding shells. The light curve of a GRB depends on the initial state and the expanding speed of the...

Temporal gamma-ray spectrometry to quantify relative fissile material content

Creator:: Williford, Russell S.
Abstract:: A new method for delayed gamma-ray spectrometry to quantify the relative content of fissile material is developed and demonstrated to support international efforts in bolstering non-destructive assay capabilities. Previous traditional delayed gamma-ray spectrometry techniques rely upon nuclear data that often carry very high uncertainty. The new method removes the requirement...

Triple angular correlations of gamma rays in ¹¹⁰Cd

Creator:: Schulz, Norbert S.
Abstract:: An experiment has been conducted using a triple directional correlation method developed by K. S. Krane, R. M. Steffen and R. M. Wheeler (ref. 3). This method is presented and two normal detection geometries are introduced. The performance of the N1- and N2- geometry was studied in four experiments using...
