Two types of X-ray sources are currently used in X-rayCT. The most simple type is the fixed-anode X-ray tube, in which the anode is cooled by oil and is continuously energized. A typical focal spot size of this type is about 2mm×16mm on a 20° angletungstentarget. The relatively ...
As pioneers of the world’s brightest X-ray sources, Excillum is relentlessly pushing the limits of X-ray source technologies to enable new breakthroughs in manufacturing, medicine and science. New frontiers are waiting to be explored. The world’s brightest X-ray sources help make it possible....
IV. The X-Ray Source Luminosity Function and the Nature of Ultraluminous X-Ray Sources We derive the X-ray luminosity function (XLF) of the X-ray source population detected in the Chandra observation of NGC 4038/4039 (the Antennae). We explic... A Zezas,G Fabbiano - 《Astrophysical ...
opening up a new window into the universe and revealing the existence of several new classes of astronomical objects, was themost importantsingle scientific fruit of the whole space program. The newly discovered x-ray sources gave an entirely fresh picture of the universe, dominated by violent eve...
Applications of a non-interferometric x-ray phase contrast imaging method with both synchrotron and conventional sources We have developed a totally incoherent, non-interferometric x-ray phase contrast imaging (XPCI) method. This is based on the edge illumination (EI) concept... M Endrizzi,PC Die...
Today’s brightest X-ray beams are generated by synchrotron radiation (SR) sources1,2,3. In industry, biology and basic research, this radiation is used for ultrafast transient imaging with angstrom resolution. SR is produced by electrons, which are accelerated to relativistic energies and injected...
Ultra-Luminous X-ray sources (ULX) are X-ray binaries with Lx>1E^39 ergs/s. The most spectacular examples of ULX occur in starburst galaxies and are now understood to be young, luminous High Mass X-ray Binaries. The conditions under which ULX form are poorly understood, but recent evi...
The meaning of DUAL-ENERGY X-RAY ABSORPTIOMETRY is absorptiometry in which the density or mass of a material (such as bone) is measured by comparing the material's absorption of X-rays of two different energies and which is used especially for determinin
Introduction Laser-plasma hard x-ray sources are a suitable alternative to conventional accelerator-based x-ray sources of high brightness1,2and for applications requiring a high x-ray flux and a micrometric size such as x-ray phase contrast imaging3,4. Their characteristics and operating capabili...
