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.
Anomalous X-ray scattering (MAD or SAD phasing) – the X-ray wavelength may be scanned past an absorption edge [a] of an atom, which changes the scattering in a known way. By recording full sets of reflections at three different wavelengths (far below, far above and in the middle of the absorption edge) one can solve for the substructure of ...
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.
X-ray fluorescence (XRF) is the emission of characteristic "secondary" (or fluorescent) X-rays from a material that has been excited by being bombarded with high-energy X-rays or gamma rays.
The Rowley Village Forge Site is a historic colonia-era iron foundry site in Boxford, Massachusetts. The first iron forge in the area was established on Fish Brook in 1668 by Henry Leonard of the Leonard family, who were instrumental in the Saugus Iron Works further south. This business ran until about 1681, but the site also saw industrial ...
It was incorporated as a separate town in 1853. One notable resident from Lakeville who fought in the American Revolution was a Wampanoag man named Benjamin Simonds, who was an aide-de-camp to George Washington at Valley Forge, who died in either 1831 or 1836. He was likely a part of one of the two militias from Lakeville, the Pond Militia ...
