Investigations of the cascade of Langmuir wave turbulence over HAARP Observatory in Gakona, Alaska
This thesis investigates the cascade lines from Langmuir wave turbulence as a result of Parametric Decay Instability (PDI) in the ionosphere. This effect is studied using a high-frequency (HF) heater located at the NSF/DoD High Frequency Active Auroral Research Program (HAARP) Observatory in …

Excitation of Langmuir wave turbulence in high-frequency (HF) pump waves over Gakona, Alaska
… thesis are the excitation and observation of Langmuir wave turbulence caused by the parametric decay instability (PDI) in high-frequency space plasma heating experiments conducted at the NSF/DoD High Frequency Active Auroral Research Program (HAARP) facility in Gakona, Alaska during the spring …

Simultaneous multi-angle measurements of plasma turblence at HAARP
… HF transmitter to generate and study strong Langmuir turbulence (SLT) in the interaction region of overdense ionospheric plasma. Diagnostics included the Modular UHF Ionospheric Radar (MUIR) sited at HAARP, the Super DARN-Kodiak HF radar, and HF receivers to record stimulated electromagnetic …

Simulation of ionospheric plasma heating experiments in the versatile toroidal facility
… of either hydrogen or argon. The HF "pump" wave of ionospheric experiments is modeled by 2.45 GHz microwaves, launched perpendicular to the magnetic field and the density gradient of the VTF in the ordinary mode. The peak plasma density is several times greater than the critical density (nc …
