Abstract

Trace rare gases optical emission spectroscopy has been used to measure the electron temperature (Te) in a high-density inductively coupled dichloride-argon (Cl2-Ar) plasma at 0.018Torr as function of the radio-frequency power of 13.56MHz frequency and argon (Ar) fraction. Only the krypton (Kr) and xenon (Xe) emission lines were used to determine electron temperature (Te) because of evidence of radiation trapping, when the argon emission lines were also used for larger Ar fractions. At 600W, electron temperature (Te) increases from 4.06±0.5eV to 6.06±2.0eV as the Ar fraction increases from 1% to 96%. In the inductive mode, electron temperature (Te) for chlorine plasma, including 1% of each He, Ne, Ar, Kr and Xe, increases only slightly from 3.8eV to 4.0eV as power increases from 450W to 750W. This increase is much larger for larger Ar fractions, such as from 4.0eV to 7.3eV for 78% Ar. Most of these effects can be understood using the fundamental particle balance equation.

Abstract

Special algorithm for FEL amplifier at saturation effects were dedicated to visualizing intensity distribution in planar undulator depending on one-dimension FEL amplifier theory. This efficient algorithm for FEL Simulation Code has been applied to study the field gain distribution along the undulator length to explain high gain FEL operating mechanism in nonlinear regime.

Abstract

Thin multilayer graded semiconducting, inorganic, metallic oxides films have wide applications such as optical designs and microelectronics industry. Knowledge of the refractive indices nf(λ) and of such films their dispersion are important. This paper is aimed to present an overview on the different methods that have been devised for the determination of the index of refraction of thin films along with their theoretical basis. Such methods are Abeles, Swanepoel, Kramers-Kronig, Ellipsometer, and others. Some experimental results are also presented. The accuracy of these methods is evaluated.

Abstract

The aim of this work is to produce composite materials with ceramic base covered by a layer of aluminum and its alloys by means of self infiltration. Al2O3 powder was used after been pressed by different pressures (58MPa, 117MPa and 176MPa) in metallic mold. The sintering process has been preformed at 1200°C for two hours. After that, the porosity percentage was measured and the samples were heated to 700°C and then immersed in the molten pure aluminum and its alloys and heated to about 1000°C for half an hour .Then the samples were cooled to 650°C and examined by an optical microscope and the scanning electron microscope. Moreover, the x-ray diffraction for the samples has been employed to define the structure of the resulting composite .The testing results reveal that the immersing process can be successfully done in Al-Mg alloy to obtain composite material of ceramic base with metal layers.

Abstract

In this work, ZnO thin films were prepared using spray paralysis technique at different molarities of aqueous zinc chloride solution. This study focused on the effect of morality on the optical and electrical properties, therefore, many samples were produced to explore and determine the optimum characteristics of the prepared samples. These properties include the optical properties such as transmittance, bandgap energy, skin depth, carrier concentration, photoconductivity, absorption edge shift, optical constants such as absorption coefficient and extinction coefficient, and electrical properties such as I-V characteristics, electrical conductivity and resistivity under dark or illumination conditions.
