Thesis – Table of Contents Wavelet Analysis to Calculate Power Spectra Overview Wavelet analysis techniques, while not as commonly understood as Fourier analysis, are nonetheless frequently applied to problems in which time and frequency information are desired simultaneously. Analysis suites such as IDL (popular in plasma physics circles) provide complete libraries for easily incorporating these […]

## Thesis – Chapter 7: Conclusions

Thesis – Table of Contents Conclusions Studies of filamentary pressure structures are an ongoing work within the LAPD-U laboratory. The work of Burke, et al. [1998, 2000a, b] (and [Burke, 1999]) established the ability of this experimental geometry to observe classical transport in magnetically confined plasmas. An increase in transport and the loss of classical […]

## Thesis – Chapter 6: Plasma Flow Parallel to Background Magnetic Field

Thesis – Table of Contents Plasma Flow Parallel to Background Magnetic Field Plasma flow is studied in relation to another aspect of this thesis, namely the thermal wave. This section examines describes flows aligned with the applied background magnetic field, i.e., parallel flows. Spatiotemporal Behavior and Modeling A comparison of the time evolution of parallel […]

## Thesis – Chapter 5: Comparison between Temperature Filament and Limiter-Edge Experiments

Thesis – Table of Contents Comparisons Between Turbulent Features of the Temperature Filament and Limiter-Edge Experiments About the Limiter-Edge Experiment The limiter-edge experiment focuses on properties and generation of intermittent, or bursty, turbulence structures. As with the temperature filament experiment of this thesis, the turbulence study is motivated by the relevance to transport. Intermittent turbulence […]

## Thesis – Chapter 4: Exponential Frequency Spectrum and Lorentzian Pulses (Part 2)

Thesis – Table of Contents Exponential Frequency Spectrum and Lorentzian Pulses (cont.) 4.3 Lorentzian Pulses The normalized form of a temporal Lorentzian pulse, L(t) , is (Eq. 4.1), where the pulse is centered at time to and has width τ. In 4.1, the time width is equal to one-half of the full width at half […]

## Thesis – Chapter 4: Exponential Frequency Spectrum and Lorentzian Pulses (Part 1)

Thesis – Table of Contents Exponential Frequency Spectrum and Lorentzian Pulses During the early evolution of the temperature filament a pressure gradient forms in response to input heating from an electron beam. At these early times, the transport of thermal energy is observed to be in agreement with classical theory. This Chapter is concerned with […]
