Gadolinium oxysulfide phosphor doped with trivalent terbium have been synthesized using urea homogenous precipitation and followed by sulfurization at 800 °C under argon atmosphere. Structural and morphological of synthesized phosphor powder were characterized by x-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier transform infrared spectrometry (FT-IR). Hexagonal structure ...
Recent experiments at the 20 MA Z Accelerator have demonstrated, for the first time, implosion velocities up to 110–130 cm/ls in imploding stainless steel wire arrays. These velocities, the largest inferred in a magnetically driven implosion, lead to ion densities of 2 Â 10 20 cm À3 with electron temperatures of $5 keV. These plasma conditions have resulted in significant increases in the K-she...
Image entropy as prior in Bayesian inference was applied to the restoration of X-ray digital images with additive zero mean Gaussian distributed noise. An iterative algorithm based on a conjugate gradient method with numerical evaluation of partial derivatives was developed to efficiently minimize the potential function associated to any positive, additive distribution. The correlation matrix o...
We demonstrate directional output from a deformed disk laser of dimensions comparable to the emission wavelength. Unlike larger deformed cavity lasers, which exhibit universal output directionality determined by chaotic ray dynamics, the far-field patterns differ between lasing modes. The directional emission results from weak coupling of isotropic high-quality modes to anisotropic low-quality ...
