Effects of a magnetic field on the double-probe technique are studied experimentally by means of symmetric floating computer controlled fast double probes in low and intermediate pressure plasmas. In addition, the effects of the magnetic field on the electron temperature, electron density, and electric field have been investigated. As it is expected, when there is no magnetic field, properties of the discharge plasma are best described by Langmuir theory. Whereas, when there’s a magnetic field of sufficient strength Schottky’s theory of ambipolar diffusion applies.

Analysis of preformed plasma condition of Ni-like Mo X-ray laser media
İnce, Sevi; Bilikmen, Kadri Sinan; Department of Physics (2006)
The aim of this work is to produce X-ray laser source from a plasma produced by focusing a pulsed laser beam on a solid target. Preformed Molybdenum plasma is created by using Nd:YAG laser pulses with a pulse duration 6 ns and pulse intensity 5.09x1011 W/cm2. Detailed simulations of Ni-like Mo X-ray laser media are undertaken using the EHYBRID code which is a hydrodynamic code. X-ray resonance lines between 25 Å and 40 Å emitted from the molybdenum plasma have been obtained and analysed. EHYBRID code also g...
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...
Gravitational waves and gravitational memory
Korkmaz, Ali; Tekin, Bayram; Department of Physics (2018)
We study the gravitational waves produced by compact binary systems in the linear regime of massless general relativity and calculate the gravitational memory produced by these waves on a detector.
Measurement of the production cross section for pairs of isolated photons in pp collisions at root s=7 TeV
Chatrchyan, S.; et. al. (Springer Science and Business Media LLC, 2012-01-01)
The integrated and differential cross sections for the production of pairs of isolated photons is measured in proton-proton collisions at a centre-of-mass energy of 7TeV with the CMS detector at the LHC. A data sample corresponding to an integrated luminosity of 36 pb(-1) is analysed. A next-to-leading-order perturbative QCD calculation is compared to the measurements. A discrepancy is observed for regions of the phase space where the two photons have an azimuthal angle difference Delta phi less than or sim...
Simulation of the stabilization of magnetic islands by ecrh and eccd
Ayten, Bircan; Bilikmen, Kadri Sinan; Department of Physics (2009)
An almost universal instability in high pressure plasmas is the Neoclassical Tearing Mode (NTM). NTMs are driven by local perturbations in the current density and result in magnetic island like deformations of the magnetic topology. They can be stabilized by compensating the current perturbations with local electron cyclotron resonance heating (ECRH) or with non-inductive current drive (ECCD). The modified Rutherford equation describes the nonlinear evolution of tearing modes as determined by various contri...
