DTL cavity design and beam dynamics for a TAC linear proton accelerator
(Chinese Physics C, 2012-02)
A 30 mA drift tube linac (DTL) accelerator has been designed using SUPERFISH code in the energy range of 3-55 MeV in the framework of the Turkish Accelerator Center (TAC) project. Optimization criteria in cavity design are ...
The Effect of Excess Y2O3 Addition on the Mechanical Properties of Melt-Processed YBCO Superconductor
(SPRINGER, 233 SPRING ST, NEW YORK, NY 10013 USA, 2010-12)
In this study, two kinds of melt-processed YBCO samples with Y2O3 addition were fabricated and their microstructures were defined by XRD analysis and polarized light optical microscopy. The mechanical properties of these ...
The Effect of Y2O3 on AC Susceptibility Measurements of MPMG YBCO Superconductor
(SPRINGER, 233 SPRING ST, NEW YORK, NY 10013 USA, 2013-04)
In this study, two kinds of melt-powder-melt-growth (MPMG) YBCO sample grown on a buffer layer of Y2O3 addition were fabricated. The compacted powders were located on a crucible with Y2O3 powder freely poured and a buffer ...
Effects of random material and geometrical properties on structural safety of steel–concrete composite systems
(INTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN BIOMEDICAL ENGINEERING, 2011)
A stochastic finite element-based algorithm for probabilistic analysis of structural systems made of composite sections with random material and geometrical properties under earthquake forces is proposed in this paper. ...
Elevated temperature resistance of welded tubular joints under axial load in the brace member
(Engineering Structures, 2014)
This paper presents the results of a study to obtain the ultimate capacity of welded steel tubular joints at elevated temperatures. Finite Element (FE) simulations of welded tubular joints with axially loaded brace member ...
Lateral variations of the modal (a/b) values for the different regions of the World
(Journal of Geodynamics, 2002)
Several catalogues of global earthquakes reported for the time period from 1900 to 2000 have been compiled to examine lateral variations of the modal (a/b) values as derived from the Gutenberg–Richter empirical law. For ...
Levitation force at different temperatures and superconducting properties of nano-structured MgB2 superconductors
(ELSEVIER SCIENCE SA, PO BOX 564, 1001 LAUSANNE, SWITZERLAND, 2010-03-04)
The levitation and pinning force properties of nanocrystalline MgB2 superconductors prepared by a mechanical alloying technique with varying milling duration have been investigated. Levitation force measurements under ...
Magnetic Properties of YBCO Single-Crystal Grown on Y2O3 Layer by a Cold Top-Seeding Method
(SPRINGER, 233 SPRING ST, NEW YORK, NY 10013 USA, 2012-02)
In this work, single-crystal samples 20 mm in diameter were grown by a cold top-seeding method. In order to study the effect of an Y2O3 buffer layer, a compacted precursor was located in a crucible on a buffer layer of ...
Measurment of L X-Ray Production Cross-Sections and Li Subshell Florescence Yields
(Journal of Electron Spectrometry And Related Phenomena, 2003-04-03)
Li (i=1, 2 and 3) X-ray production cross sections have been measured for 14 elements in the atomic number range 55≤Z≤81 at 15.73 keV. The values of Li subshell fluorescence yields (ω1, ω2 and ω3) have been determined using ...
A New Method to Compensate for Counting Losses due to System Dead Time
(Nuclear Instruments and Methods in Physics Research A, 2009-05-21)
Determination of count losses and pile-up pulse effects in quantitative and qualitative analysis became a vital step in various analyses. Therefore, compensating for counting losses is of importance. These counting losses ...
