High-field pinning potential in YBCO films with nanoengineered pinning centres
(Springer, 2015)
Frequency-dependent AC susceptibility measurements have been used to estimate the critical current densities and pinning potential of two 1.1-mu m-thick YBCO films with nanoengineered pinning centres. the films were grown ...
The effect of magnetic field distribution and pole array on the vertical levitation force properties of HTS maglev systems
(Ieee-Inst Electrical Electronics Engineers Inc, 2015)
In this paper, the levitation force measurements have been carried out by the magnetic force measurement system under both field-cooling and zero-field-cooling regimes, whereas the magnetic field distribution over the ...
Design and simulation of 31/2-cell superconducting gun cavity and beam dynamics studies of the SASE-FEL System at the Institute of Accelerator Technologies at Ankara University
(Elsevier Science Bv, 2015)
Design and simulation of a superconducting gun cavity with 31/2 cells have been studied in order to give the first push to the electron beam for the linear accelerating system at the Institute of Accelerator Technologies ...
Determination of tritium concentrations in humans before the development of a nuclear power plant in Turkey
(Taylor & Francis Ltd, 2015)
The most widely used method to determine the level of tritium in humans is testing urine. Tritium concentrations in urine samples of 100 persons aged 18-66 years selected randomly from a pilot region in Turkey were analysed. ...
Cu(In,Ga)(Se,Te)(2) pentenary thin films formed by reaction of precursor layers
(Elsevier Science Sa, 2015)
Sodium doped CuIn(1 - x) Ga-x(Se(1 - y) Te-y)(2) (CIGST) thin films were grown on Mo-coated soda lime glass substrates by a two-stage technique. the effects of Te content and annealing temperature on the microstructural ...
The nanoscale structure and unoccupied valence electronic states in FeSe1-xTex chalcogenides probed by X-ray absorption measurements
(Royal Soc Chemistry, 2015)
We have studied the nanoscale structure and unoccupied electronic states in FeSe1-xTex by a combined analysis of Se K, Te L-1 and Fe K-edges X-ray absorption measurements. Extended X-ray absorption fine structure (EXAFS) ...
The size effect on the magnetic levitation force of MgB2 bulk superconductors
(Elsevier Sci Ltd, 2016)
In this study, the size effect on the magnetic levitation performance of disk-shaped MgB2 bulk superconductors and permanent magnets was investigated. MgB2 samples with varying diameters of 13 mm, 15 mm and 18 mm, each of ...
Influence of copper composition and reaction temperature on the properties of CZTSe thin films
(Elsevier Science Sa, 2016)
In this study Cu2ZnSnSe4 (CZTSe) compound layers were grown using a two-stage technique that involved deposition of metallic precursors (Cu, Zn, and Sn) and Se in the first stage, followed by reaction of all the species ...
Dynamic magnetic hysteresis properties in a two-dimensional mixed ising system designed with integer and half-integer spins
(Springer, 2016)
Dynamic magnetic hysteresis properties in a two-dimensional mixed Ising system designed with integer and half-integer spins, namely spin-1 and spin-5/2, are investigated comprehensively on the basis of the mean-field ...
Distribution of Cs-137 in the mediterranean mussel (Mytilus galloprovincialis) in Eastern Black Sea Coast of Turkey
(Pergamon-Elsevier Science Ltd, 2016)
This study presents the results of Cs-137 and K-40 radionuclide concentrations in mussel (Mytilus galloprovincialis) samples collected during the period of February-November 2014 from twelve different stations within the ...
