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.
Neil Gehrels Swift Observatory, previously called the Swift Gamma-Ray Burst Explorer, is a NASA three-telescope space observatory for studying gamma-ray bursts (GRBs) and monitoring the afterglow in X-ray, and UV/visible light at the location of a burst. [5]
The x-ray tube was removed to render the apparatus harmless before being put on public display, due to the possible risk of radiation burn or other health problems if it were switched on. The risk of radiation burns to extremities was known since Wilhelm Röntgen 's 1895 experiment, but this was a short-term effect with early warning from ...
X-ray telescopes were first used for astronomy to observe the Sun, which was the only source in the sky bright enough in X-rays for those early telescopes to detect. Because the Sun is so bright in X-rays, early X-ray telescopes could use a small focusing element and the X-rays would be detected with photographic film.
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
First short burst with a detected radio, optical, and X-ray counterpart, as well as an unambiguous association with an elliptical galaxy. GRB 060218: z = 0.0331 [Ref 8] Swift: First GRB with an accompanying supernova which could be tracked starting immediately after the burst. GRB 060614: R.A. 21 h 23 m 27.0 s Decl. −53° 02′ 02″ z = 0. ...
Scorpius X-1 was the first extrasolar X-ray source discovered, and, aside from the Sun, it is the strongest apparent non-transient source of X-rays in the sky. [3] The X-ray flux varies day-to-day, and is associated with an optically visible star , V818 Scorpii , that has an apparent magnitude which fluctuates between 12-13.
X-ray microscopes are sometimes used for these analyses because the samples are too small to be analyzed in any other way. A square beryllium foil mounted in a steel case to be used as a window between a vacuum chamber and an X-ray microscope. Beryllium, due to its low Z number, is highly transparent to X-rays.
