The Maryland Centrifugal eXperiment (MCX) is a novel rotating mirror plasma, which is axially confined by the centrifugal force. The interchange modes can be stabilized by the shear in the azimuthal rotation velocity. Both these goals can be accomplished if the rotation speeds are supersonic with a Mach number~5. So far Mach numbers~2 have been accomplished. Thus residual interchange fluctuations are observed on sixteen magnetic pick-up coils placed azimuthally at an axial location mid-way between the central section and the mirror throat. The fluctuations are analyzed and modeled using a low-dimensional system of equations for the interchange mode coupled to zonal flows.

High gradient plasma waves to accelerate charged particles
Yedierler, Burak; Bilikmen, Kadri Sinan; Department of Physics (2002)
In this thesis one of the most promising plasma based particle acceleration methods, the Laser Wakefield Acceleration (LWFA) mechanism is discussed in detail. Starting from the standard LWFA method, the wakefield generation in plasmas and the energy gain of electrons are formulated. The wakefield generation by a multi passage laser beam in a plasma model based on the resonant LWFA is proposed. The growth of the wakefield amplitude is demonstrated and the corresponding energy gain of electrons is calculated....
Low temperature operation of APD for quantum cryptographic applications
Kale, Zuhal; Ergül, Rüyal; Department of Electrical and Electronics Engineering (2005)
This thesis explains low temperature operation of an InGaAs Avalanche Photo Diode (APD) cooled using thermoelectric coolers in order to utilize in the quantum cryptographic applications. A theoretical background for the equipment used in the experiment was provided. Circuitry and mechanics used for the low temperature operation were designed. Performance measures for APD were explained and experiment results were presented.
Finite element study of biomagnetic fluid flow in a symmetrically stenosed channel
Turk, O.; Tezer, Münevver; Bozkaya, Canan (Elsevier BV, 2014-03-15)
The two-dimensional unsteady, laminar flow of a viscous, Newtonian, incompressible and electrically conducting biofluid in a channel with a stenosis, under the influence of a spatially varying magnetic field, is considered. The mathematical modeling of the problem results in a coupled nonlinear system of equations and is given in stream function-vorticity-temperature formulation for the numerical treatment. These equations together with their appropriate boundary conditions are solved iteratively using the ...
The gravitational effect on induced charge density for an obliquely rotating neutron start
De Paolis, F; Qadir, A; Tarman, Işık Hakan (1999-11-01)
The effect on the induced charge density of the gravitational field of a rotating neutron star with its magnetic axis inclined with respect to the rotational axis is investigated. While gravitation increases the charge density the obliquity reduces it.
Observations and analysis of magnetic fluctuations in the Maryland centrifugal experiment
Choi, S.; Guzdar, P. N.; Case, A.; Ellis, R.; Hassam, A. B.; Lunsford, R.; Teodorescu, C.; Uzun Kaymak, İlker Ümit (AIP Publishing, 2008)
Initial results from magnetic probes on the Maryland Centrifugal eXperiment (MCX) [R. F. Ellis , Phys. Plasmas 8, 2057 (2001)] provide details of the propagation and azimuthal mode structure of magnetic fluctuations in the edge region. Magnetic coils placed azimuthally along the edge measure changes in the axial magnetic field during the time history of the plasma discharge. The eight evenly spaced coils can resolve azimuthal modes up to m=3. The plasma rotates azimuthally in MCX due to an applied radial el...
