This thesis deals with a one and two dimensional numerical modeling of a low-pressure DC glow discharge in argon gas. We develop two-component fluid model which uses the diffusion-drift theory for the gas discharge plasma and consists of continuity equations for electrons and ions, as well as Poisson equation for electric field. Numerical method is based on the control volume technique. Calculations are carried out in MATLAB environment. Computed results are compared with the classic theory of glow discharges and available experimental data.

Ion implantation and deposition on the inner surfaces of cylinders by exploding metallic foils
Demokan, O (2000-10-01)
A novel scheme for ion deposition and possibly ion implantation on the inner surfaces of cylindrical targets is proposed and experimentally tested. A large current is passed through a coaxial table-type structure, composed of a straight conductor and a thin metallic foil, surrounding it. The foil evaporates and ionizes forming a metallic plasma, which is pushed radially outward due to the pressure of the magnetic field, confined to the region between the plasma and the conductor. The ions of the foil materi...
Investigation of dc generated plasmas using terahertz time domain spectroscopy
Karaoğlan, Gülten; Altan, Hakan; Department of Physics (2010)
This thesis is on the topic of investigation of the characteristics of DC Glow Discharge plasmas. Emphasis is given on characterizing the plasma electron density. The methods of generating and detecting THz pulses are described. THz transmission spectroscopy and plasma emission spectroscopy is examined. Transmission spectrum is taken for Air, gaseous Nitrogen and Argon plasmas. Moreover, emission spectrum of Air, N2 and Ar plasma analysis were done respectively. It was found that the transmission of teraher...
Numerical analysis of radio frequency inductively coupled ion thruster and computation of its performance parameters
Bozkurt, Erdal; Alemdaroğlu, Nafiz.; Department of Aerospace Engineering (2019)
The main goal of this thesis is geometric and parametric analysis of a simulated cylin-drical two-gridded Radio Frequency Inductively Coupled (RF-ICP) ion thruster. Inaddition, instrumental performance of this thruster and the effects of a fixed shapeof the electrodes on ion trajectories are investigated. The simulations of the plasmaand the ion optics are performed by using COMSOL Multiphysics software. The firststep is checking the reliability of the software. Radial and axial simulation parametricresults...
Modelling of a nonequilibrium spherical electric discharge under higher modes of incident microwaves
Rafatov, İsmail; Çakır, Serhat (2005-05-02)
The work deals with the modelling of a nonequilibrium spherical microwave discharge. An effect of the higher modes of the incident electromagnetic waves on the properties of the discharge plasma is investigated. Numerical experiments are carried out for the discharge in an argon at atmospheric pressure. Results are presented for the characteristics of the discharge plasma against the external parameters (the mode, frequency and power of the applied electromagnetic field and the size of the discharge chamber).
Adsorption of aromatic molecules on rutile TiO2(110) surfaces
Mesta, Murat; Ellialtıoğlu, Süleyman Şinasi; Department of Physics (2009)
Transition metal oxides having high dielectric constants and wide band gaps find very important and interesting technological applications in surface physics. In particular, titania is the most commonly used material in heterogeneous catalysis because of its stable and flat surfaces. Having Ti cations at different charge states within the system brings about various novel electronic properties which are mainly surface related. Adsorption of catalytically important or chemically useful molecules on titania s...
