Refractive effects in phase objects and associated phenomena.
The effect of the refraction of a laser beam propagating through three different phase objects, i.e. a laser produced plasma and two different gas media, is investigated in this thesis. It is shown that these effects ...
Linear and nonlinear electron-acoustic waves in plasmas with two electron components.
Measurements of broadband electrostatic wave emIssons in conjunction with particle distributions in the earth's magnetosphere, have provided motivation for a number of studies of waves in plasmas with two electron components. ...
Velocity, vorticity and turbulence measurements in the surf zone.
The coastal regions of the world play a significant role with regards to social and economic development, and with the ever increasing human activities along the coast, it has become necessary to understand and protect ...
Electrostatic wave phenomena in dusty plasma.
This thesis is concerned with the some aspects of electrostatic wave phenomena dusty plasmas. In particular Debye shielding, nonlinear potential structures such as diploar vortices and solitons are investigated. The ...
The measurement of electric quadrupole moments of gas molecules by induced birefringence.
Determining the electric quadrupole moments of gas molecules from measurements of birefringence induced in the gas by an applied electric field gradient is widely recognised as being the most direct experimental technique ...
The influence of rotating and locked magnetic islands on edge transport in Tokoloshe tokamak.
The turbulence and fluctuation induced transport in the edge plasma of the Tokoloshe tokamak was studied using a Langmuir probe array. In this thesis three separate experiments are presented, each of which examines a ...
Low frequency electrostatic instabilities in a two-dust component plasma.
The kinetic dispersion relation for a magnetized dusty plasma comprising of ions, electrons and massive, charged dust particles is solved for low frequency electrostatic instabilities in the dust plasma frequency ...
A study of plasma source ion implantation.
The work described in this thesis is an analysis of the Plasma Source Ion Implantation (PSII) process. A metal target is placed within a plasma, and pulsed to a high negative potential (10 - 50 kV). The electrons in the ...

The effect of antisymmetrization in diquark models of baryons.
In this thesis the effect of antisymmetrization in diquark models of baryons composed of light (u and d) quarks is investigated. The diquark in this study is considered alternately as a pointlike and as a composite ...
