Opis:: Cancer is one of the most deadly diseases posing threat for our health. The most important method for eradicating of cancer cells is photoradiotherapy. Electrons accelerated by the accelerator are converted to photons in the process of bremsstrahlung. These photons are focused on diseased cells. Photon leaving accelerator head should assure a given dose intensity in cancer cells. Measuring of beam parameters at apparatus output is essential to determine the dose. In this study, Suleyman Demirel University research and education hospital in radiation Oncology department which has located at 18 MeV accelerator in energy gamma dose was measured.

Opis:: Single crystal $Y_3Fe_5O_{12}$ (YIG) film was grown onto (111) oriented gadolinium gallium garnet (GGG) substrate by the liquid phase epitaxy (PLD) technique. The X-ray diffraction measurements showed that epitaxial growth of the film along its (111) axis. The surface characteristic was investigated by atomic force microscopy (AFM) measurement. The magnetic field sensor consisted of a rectangular shape with 5 mm wide, 15 mm long and 5 μm thick YIG film and a pair of identical 50 μm wide microstrip copper transducers elements separated by 6 mm. The filter was tested by measuring reflection $S_{11}$ characteristic at various bias magnetic fields. The results have showed that when the bias field increased from 0 to 2.5 kOe, the frequency value corresponding to $S_{11}$ maxima increased from 1 GHz to 9 GHz. This suggests that the wide range magnetic field sensing and the highly sensitive field sensing are simultaneously fulfilled with the YIG film.

Opis:: The $L_{3l},$ $L_{3α},$ $L_{3β},$ $L_{2β},$ $L_{2γ},$ $L_{2η},$ $L_{1β}$ and $L_{1γ}$ X-ray production cross-sections and L shell average fluorescence yields were measured for the elements from Re to U using excitation energy of 123.6 keV. Measurements were performed using an $\text{}^{57}Co$ annular radioactive source and a Si(Li) detector. The theoretical values of the cross-sections were calculated using theoretically tabulated values of subshell photoionization cross-sections;the Coster-Kronig transition probabilities were based on the Dirac-Hartree-Slater theory and radiative emission rates. Experimental results were compared with the theoretically calculated values of L shell X-ray cross-sections. The present experimental results are in agreement with theoretical values.

Opis:: In this work, the technological aspects of great importance $YBa_2Cu_3O_{7-x}$ superconducting materials were produced in the form of nanotube by electrochemical method. The electrochemical deposition conditions for the Y-Ba-Cu deposition in nanoporous $Al_2O_3$ were investigated. The heat treatment was applied to $Y-Ba-Cu//Al_2O_3$ nanopatterns, to form superconductive phase. The resulting nanostructures were found to be in length 4-5 μm, 177-210 nm in diameter. The produced nanostructures at - 4 V and more positive potentials were Y-Ba-Cu nanowires, while the nanostructures deposited at the more negative potentials were of nanotube form.

Opis:: In this study, densely packed $Co_3O_4$ nanotubes for supercapacitors have been obtained by means of chemically depositing cobalt hydroxide within a porous anodic aluminum oxide and then annealed at 360°C. The morphological properties obtained $Co_3O_4$ nanotubes were studied by scanning electron microscopy, the chemical composition was determined by examination of the energy dispersive X-ray spectra. Supercapacitor characteristics such as charging/discharging and impedance (Z) characteristics were also examined.
