Cathode Spot Injection of Dielectric Particles with Applications for Communications Blackout Plasma Depletion.
(2012)
Vehicles traveling at hypersonic velocities in the atmosphere are readily enveloped by a dense plasma layer that blocks, reflects, and significantly attenuates radio signals typically used for communications. This problem ...
High-Energy-Density Field-Reversed Configurations for Sub-Microsecond Magnetized Target Fusion
(2023)
Magnetized target fusion (MTF) has gained popularity in recent decades as potentially a more economic route to fusion gain greater than unity in the laboratory. The magnetized liner inertial fusion (MagLIF) program on the ...
Modeling Dose-Function Response and Toxicity Pathways in Non-Small Cell Lung Cancer Patients Undergoing Radiation Treatment
(2021)
Radiotherapy is currently the standard of care for treating NSCLC patients, and while technological advancements in the field continue to improve our ability to successfully treat these patients, serious side-effects, i.e. ...
Spacecraft Charge Neutralization During Active Electron Emission
(2020)
Active (i.e. deliberate) electron emission in space is a powerful scientific technique that often proves problematic due to the spacecraft charging it induces. Indeed, effective spacecraft neutralization during active ...
The Importance of Light Collection Efficiency in Radiation Detection Systems That Use Organic Scintillators
(2018)
An organic scintillator is a transparent material that fluoresces when ionizing radiation interacts with it, making it a suitable radiation detector when coupled to a light-readout electronic device, such as a photomultiplier ...
The Plasma Water Reactor: A Geometric Approach to Scaling Electric Discharges for Water Treatment
(2019)
Advanced oxidation processes (AOPs) are established disinfection methods that can remove contaminants of emerging concern (CECs) by producing hydroxyl radicals and other reactive oxygen species (ROS) in situ. Production ...
Electron Acceleration and Radiation Generation from Relativistic Laser-Plasma Interactions and Statistical Methods at High Repetition-Rate
(2021)
This dissertation explores the interaction between high-intensity lasers and plasmas to accelerate electrons and produce radiation via experimental and computational efforts. The laser pulses used in this dissertation have ...
Effects of Pre-Ionization on the Gas-Puff Z-Pinch
(2022)
This dissertation presents: (1) the development of a gas-puff z-pinch system for the MAIZE pulsed power facility; (2) experiments carried out to characterize the system’s performance on MAIZE; and (3) experiments to test ...
Fast Magnetic Reconnection in Relativistic Laser-Plasma Interactions.
(2016)
Magnetic reconnection is a fundamental plasma process involving the transfer of magnetic potential energy to plasma kinetic energy through changes in the magnetic field topology. Results are presented of experimental ...
Kinetic Theory of Strongly Magnetized Plasmas
(2023)
Coulomb collisions in plasmas are typically modeled using the Boltzmann collision operator or its variants. These apply to weakly magnetized plasmas in which the typical gyroradius of particles significantly exceeds the ...
