Longitudinally pumped Ni-like Mo x-ray laser media is modeled using EHYBRID and a post-processor code. The required atomic data are obtained using the Cowan code. In this study the pre-formed plasma is pumped on longitudinal direction with a grazing angle. Variation of the x-ray laser gain of the 18.9 nm and 18.2 nm Ni-like Mo lines according to the incidence angle of the main heating pulse normal to the target surface is calculated for different main pulse energies. X-ray resonance lines between 26 and 37 angstrom emitted from molybdenum plasma have been simulated using post-processor coupled with EHYBRID.

Production and characterization of porous titanium alloys Esen, Ziya; Bor, Şakir; Department of Metallurgical and Materials Engineering (2007) In the present study, production of titanium and Ti6Al4V alloy foams has been investigated using powder metallurgical “space holder technique” in which magnesium powder were utilized to generate porosities in the range 30 to 90 vol. %. Also, sintering of titanium and Ti-6Al-4V alloy powders in loose and compacted condition at various temperatures (850-1250oC) and compaction pressures (120-1125 MPa), respectively, were investigated to elucidate the structure and mechanical properties of the porous cell walls...
Simulation of thermal, mechanical and optical behavior of yag ceramics with increasing Nd3+ concentration under lasing conditions. Kenar, Necmettin; Öke, Gülay; Department of Physics (2007) Two-dimensional thermal, mechanical and optical simulations are carried out to investigate the effect of Nd3+ concentration on thermal, mechanical and optical behavior of Nd:YAG ceramic laser materials under continuous wave laser operation. In the analyses, rods are pumped longitudinally with laser diodes, in three, six, nine and twelve fold structures. Rods having diameters of 3 and 6 mm are pumped with 808 nm and 885 nm sources separately having Nd+3 concentrations of 0.6, 1, 2, 3, 4 and 6 at. %. Total ab...
Analysis of preformed plasma condition of Ni-like Mo X-ray laser media İnce, Sevi; Bilikmen, Kadri Sinan; Department of Physics (2006) The aim of this work is to produce X-ray laser source from a plasma produced by focusing a pulsed laser beam on a solid target. Preformed Molybdenum plasma is created by using Nd:YAG laser pulses with a pulse duration 6 ns and pulse intensity 5.09x1011 W/cm2. Detailed simulations of Ni-like Mo X-ray laser media are undertaken using the EHYBRID code which is a hydrodynamic code. X-ray resonance lines between 25 Å and 40 Å emitted from the molybdenum plasma have been obtained and analysed. EHYBRID code also g...
Studies on flame retardancy of polyacrylonitrile fiber treated by flame-retardant monomers in cold plasma Akovalı, G; Gündogan, G (Wiley, 1990) Plasma polymer hexamethyldisiloxane, ethyldichlorophosphate and tris(butoxyethyl)phosphate modified polyacrylonitrile fibers were examined by FTIR, XRF, and SEM and the extend of flame retardancy introduced were checked. Certain levels of concentrations of flame‐retardant elements grafted or coated at the fiber surface during plasma treatment are believed to overcome some negative effects of a number of reactions that usually are concurrent with plasma polymerization, such as crosslinking.
Modeling of a generic laser guided weapon with velocity pursuit guidance and its performance analysis using various control strategies Güner, Dünya Rauf Levent; Platin, Bülent Emre; Department of Mechanical Engineering (2004) In this thesis, a base for the modeling and analysis of laser guided weapons is constituted. In particular, the effects of several control schemes on the performance of a generic laser guided weapon system are investigated. In this generic model, it is assumed that the velocity pursuit guidance is employed via a velocity aligning seeker as the sole sensor. The laser seeker is modeled experimentally, based on data obtained by conducting a series of tests. The laser reflection is also modeled. Aerodynamic coe...
