The influence of pressure [from atmospheric pressure (AP) to 10(-2) torr] and beta-radiation (1-kGy beta doses) on the current-voltage characteristics, charge trapping effects in porous surfaces, and breakdown voltage (UB) in AP microplasmas are discussed for the first time. This is due to the zeolite cathode (ZC) exposure to beta-radiation resulting in substantial decreases in the UB, discharge currents, and conductivity due to increase in porosity of the material. Results indicated the enhancement of plasma light intensity and electron emission from the ZC surface with the release of trapped electrons which are captured by the defect centers following beta-irradiation. The porosity of the ZC and radiation defect centers has a significant influence on the electrical and optical properties of the devices manufactured on its base.

Ion implantation and deposition on the inner surfaces of cylinders by exploding metallic foils Demokan, O (2000-10-01) A novel scheme for ion deposition and possibly ion implantation on the inner surfaces of cylindrical targets is proposed and experimentally tested. A large current is passed through a coaxial table-type structure, composed of a straight conductor and a thin metallic foil, surrounding it. The foil evaporates and ionizes forming a metallic plasma, which is pushed radially outward due to the pressure of the magnetic field, confined to the region between the plasma and the conductor. The ions of the foil materi...
Kinetic study of the reaction between hydroxyl-terminated polybutadiene and isophorone diisocyanate in bulk by quantitative FTIR spectroscopy Kincal, D; Özkar, Saim (Wiley, 1997-12-05) A kinetic study of the reaction between a hydroxyl-terminated polybutadiene (HTPB) and isophorone diisocyanate (IPDI) was carried out in the bulk state by using quantitative Fourier transform infrared(FTIR) spectroscopy. The reaction is shown to obey a second-order rate law, being first order in both the HTPB and IPDI concentrations. The activation parameters obtained from the evaluation of kinetic data are Delta H-double dagger = 41.1 +/- 0.4 kJ mol, Delta S-double dagger = -198 +/- 2 J K-1 mol(-1) and E-a...
Computational elastodynamics of functionally graded thick-walled cylinders and annular coatings subjected to pressure shocks Abeidi, Abdelrahim; Dağ, Serkan (2022-12-01) A computational technique based on domain-boundary element method (D-BEM) is developed for elastodynamic analysis of functionally graded thick-walled cylinders and annular coatings subjected to pressure shock type of loadings. The formulation is built on the wave equation, which is derived in accordance with plane elastody-namics. Weighted residual statement for the wave equation is expressed by using the static fundamental solution as the weight function. Applying integration by parts and incorporating the...
Non-contact atomic force microscope in ultra high vacuum using radiation pressure excitation of cantilever with Fabry-Perot interferometer Karagöz, Ercan; Oral, Ahmet; Department of Physics (2017) In this study Non-Contact Atomic Force Microscope (NC-AFM) imaging was performed by excitation of the cantilever via radiation pressure in a custom Ultra-High Vacuum (UHV) system. Both the excitation of the cantilever and the measurement of the deflection of the cantilever were done by employing a fiber Fabry-Pérot interferometer obtained by a TiO2 coating of the fiber end. This coating allows for a several times higher interference slope. The second normal mode of the cantilever oscillation, along with the...
Beam test results from a fine-sampling quartz fiber calorimeter for electron, photon and hadron detection Akchurin, N; et. al. (1997-11-11) We present the results of beam tests with high-energy (8-375 GeV) electrons, pions, protons and muons of a sampling calorimeter based on the detection of Cherenkov light produced by shower particles. The detector, a prototype for the very forward calorimeters in the CMS experiment, consists of thin quartz fibers embedded in a copper matrix. Results are given on the light yield of this device, on its energy resolution for electron and hadron detection, and on the signal uniformity and linearity. The signal g...
