The Super Dual Auroral Radar Network (SuperDARN) of HF coherent radars has been originally designed to monitor echoes, and thus study physical processes, from within the auroral oval, the area with the most frequent ...

The diffraction efficiency is critical to the speed and sensitivity of grating-based spectroscopy instruments. This becomes particularly important for soft x-ray instruments, used on material science beamlines at synchrotrons ...

Density fluctuations in high temperature fusion plasmas have been a central challenge to the development of fusion power. They are the cause of excessive anomalous losses from the plasma and are still not fully understood. ...

According to current cosmological theory, the rate of expansion of the universe depends on the average energy densities of matter, radiation, and a possible vacuum energy described by a cosmological constant, Λ, in the ...

Arising out of the EPR debate, the Bell and Wigner inequalities of quantum theory are experimentally testable relations which address the question of quantum completeness. This thesis provides feasibility results for a ...

The enhanced Polar Outflow Probe (ePOP) satellite is to be launched in 2007. One of the 8 instruments it will carry is a Radio Receiver Instrument (RRI) which is a passive radio receiver. The RRI will detect HF (High ...

In this thesis, the relationship between several high-latitude phenomena and the ionospheric conductance in both hemispheres is studied theoretically and experimentally. Theoretically, the high-latitude electrodynamics is ...

Magnetohydrodynamic (MHD) flows in annular channels are of great current interest due to experimental search for the so-called magnetorotational instability (MRI) which is important for astrophysical applications (accretion ...

World energy demands are increasing while the ability to generate that energy currently requires relying on non-renewable, and increasingly unsustainable, sources. If this trend is going to be curbed, either the energy ...

The original objectives of this thesis were to use the new PolarDARN radars to study the convection patterns at high latitudes and to attempt to explain them in terms of reconnection. Because the IMF is important in ...
