    [35]: 99–100 [36] On June 12, 2008, Intel demonstrated a special version of Enemy Territory: Quake Wars, titled Quake Wars: Ray Traced, using ray tracing for rendering, running in basic HD (720p) resolution. ETQW operated at 14–29 frames per second on a 16-core (4 socket, 4 core) Xeon Tigerton system running at 2.93 GHz. [37]

  3. X-ray optics - Wikipedia

    en.wikipedia.org/wiki/X-ray_optics

    X-ray optics is the branch of optics dealing with X-rays, rather than visible light.It deals with focusing and other ways of manipulating the X-ray beams for research techniques such as X-ray diffraction, X-ray crystallography, X-ray fluorescence, small-angle X-ray scattering, X-ray microscopy, X-ray phase-contrast imaging, and X-ray astronomy.

    Similarly to Lyman-alpha, the K-alpha emission is composed of two spectral lines, K-alpha 1 (Kα 1) and K-alpha 2 (Kα 2). [6] The K-alpha 1 emission is slightly higher in energy (and, thus, has a lower wavelength) than the K-alpha 2 emission. For all elements, the ratio of the intensities of K-alpha 1 and K-alpha 2 is very close to 2:1. [7]

  5. X-ray fluorescence - Wikipedia

    en.wikipedia.org/wiki/X-ray_fluorescence

    X-ray generators in the range 20–60 kV are used, which allow excitation of a broad range of atoms. The continuous spectrum consists of " bremsstrahlung " radiation: radiation produced when high-energy electrons passing through the tube are progressively decelerated by the material of the tube anode (the "target").

    Natural color X-ray photogram of a wine scene. Note the edges of hollow cylinders as compared to the solid candle. William Coolidge explains medical imaging and X-rays.. An X-ray (also known in many languages as Röntgen radiation) is a form of high-energy electromagnetic radiation with a wavelength shorter than those of ultraviolet rays and longer than those of gamma rays.

  7. X-ray reflectivity - Wikipedia

    en.wikipedia.org/wiki/X-ray_reflectivity

    X-ray reflectivity (sometimes known as X-ray specular reflectivity, X-ray reflectometry, or XRR) is a surface-sensitive analytical technique used in chemistry, physics, and materials science to characterize surfaces, thin films and multilayers.

  8. X-ray microscope - Wikipedia

    en.wikipedia.org/wiki/X-ray_microscope

    An X-ray microscopy image of a living 10-days-old canola plant [1]. An X-ray microscope uses electromagnetic radiation in the X-ray band to produce magnified images of objects. . Since X-rays penetrate most objects, there is no need to specially prepare them for X-ray microscopy observatio

  9. X-ray machine - Wikipedia

    en.wikipedia.org/wiki/X-ray_machine

    An X-ray generator generally contains an X-ray tube to produce the X-rays. Possibly, radioisotopes can also be used to generate X-rays. [1]An X-ray tube is a simple vacuum tube that contains a cathode, which directs a stream of electrons into a vacuum, and an anode, which collects the electrons and is made of tungsten to evacuate the heat generated by the collision.
