We studied the effect of the laser beam focusing geometry on the continuous optical discharge (COD) properties. We used a full two-dimensional radiative gas-dynamic model for the COD, maintained by a vertical CO(2) laser beam in free air atmosphere, in the Earth's gravitational field. The model takes into account all of the factors that are of importance in laser-sustained plasma processes, and uses realistic quasi optics to describe the laser radiation propagation. Results are presented for the optical discharge parameters as functions of applied laser power and degree (f-number) to which the laser beam is focused.

Spatial variations of non-uniform argon glow discharge Akbar, D.; Bilikmen, S.; Akbar, H. (Springer Science and Business Media LLC, 2006-01-01) The spatial variation of a non-uniform glow discharge due to the different diameters of the same discharge tube on the plasma parameters is attracting a considerable attention. For this reason the fundamental spatial plasma parameters of an argon. glow discharge have been measured by using fast three couple of Langmuir double probe (TCDP) technique. The orbital motion limited (OML) theory has been used, since the probe radius is smaller than Debye length xi < 1. The axial and radial variation of the electro...
Studies of Charm Quark Diffusion inside Jets Using Pb-Pb and pp Collisions at root s(NN)=5.02 TeV Sirunyan, A. M.; et. al. (American Physical Society (APS), 2020-09-01) The first study of charm quark diffusion with respect to the jet axis in heavy ion collisions is presented. The measurement is performed using jets with p(T)(jet) > 60 GeV/c and D-0 mesons with p(T)(D) > 4 GeV/c in lead-lead (Pb-Pb) and proton-proton (pp) collisions at a nucleon-nucleon center-of-mass energy of root s(NN) = 5.02 TeV, recorded by the CMS detector at the LHC. The radial distribution of D-0 mesons with respect to the jet axis is sensitive to the production mechanisms of the meson, as well as t...
Effect of Thickness on Magnetic Properties of Fe36Co36B19.2Si4.8Mo2W2 Thin Film Prepared by Thermionic Vacuum Arc Perincek, F.; Erturk, K.; AYKOL, M.; Kucuk, I.; Akdeniz, Mahmut Vedat (Institute of Physics, Polish Academy of Sciences, 2012-01-01) Fe36Co36B19.2Si4.8Mo2W2 amorphous thin films have been produced by thermionic vacuum arc with thickness varying from 200 nm to 260 mn. X-ray diffraction has been employed to reveal a predominant amorphous phase in the as-prepared samples, although a small crystalline fraction cannot be excluded. The bulk magnetic properties of thin films were examined at room temperature using an ADE Magnetics EV9 vibrating sample magnetometer with maximum magnetic field strength of 1750 kA/m, real-time field control and dy...
Effect of parallel and antiparallel configuration on magnetic damping in Co/Ag/Co/Gd Demirtas, S.; Salamon, M. B.; Koymen, A. R. (AIP Publishing, 2011-06-01) When two ferromagnetic layers have a common resonance frequency, the usual spin-pumping broadening may be reduced by dynamic exchange coupling. Utilizing the antiferromagnetic coupling between Co and Gd, we explore the change in ferromagnetic resonance accompanying a spontaneous transition from parallel to antiparallel magnetic alignment of two Co films below the compensation temperature T-comp. Above T-comp, the data are consistent with conventional models. However, a rapid doubling of magnetic damping acc...
Tuning Optical Absorption Edge by Composition and Temperature in TlGaS2xSe2((1-x)) Layered Mixed Crystals (0 <= x <= 1) Hasanlı, Nızamı (Institute of Physics, Polish Academy of Sciences, 2012-10-01) Optical properties of TlGaS2xSe2((1-x)) mixed crystals (0 <= x <= 1) have been studied using the transmission and reflection measurements in the wavelength range of 400-1100 nm. The optical indirect band gap energies were determined through the analysis of the absorption data. It was found that the energy band gaps increase with increase of sulfur atoms content in TlGaS2xSe2(1-x) mixed crystals. From the transmission measurements carried out in the temperature range of 10-300 K, the rates of change of the i...
