Interstellar gas and X-rays toward the Young supernova remnant RCW 86; pursuit of the origin of the thermal and non-thermal X-ray

open access: yesJournal of High Energy Astrophysics, 2017
We have analyzed the atomic and molecular gas using the 21 cm HI and 2.6/1.3 mm CO emissions toward the young supernova remnant (SNR) RCW 86 in order to identify the interstellar medium with which the shock waves of the SNR interact.

X-ray microscopy

Nuclear Instruments and Methods in Physics Research, 1983
Owing to the short wavelengths of X-radiation X-ray microscopes allow higher resolution than optical microscopes. In contrast to electron microscopes, X-radiation can be used to study relatively thick aqueous specimens in their natural environment. X-ray microscopes require intense X-radiation, which is best provided by electron storage rings, as well ...

X-Ray and X-Ray-CT

2011
Since their discovery in 1895, X-rays have been widely used for imaging humans. Recently, they have also gained an importance in small animal imaging (SAI). Most techniques known from clinical medicine, including single- and dual-energy X-ray imaging, have been successfully ported to SAI and are the subject of this chapter.

X-Rays and X-Ray Diffraction

2012
X-rays are an electromagnetic radiation of short wavelength, and can be produced by the sudden deceleration of rapidly moving electrons at a target material. If an electron falls through a potential difference of V volt, it acquires an energy eV electron-volt (eV), where e is the charge on an electron.

Demonstration of X-ray Holography with an X-ray Laser

Science, 1987
An x-ray hologram was made by means of an x-ray laser and a laser-quality near normal incidence x-ray mirror. The high brightness and large coherence lengths of x-ray lasers now offer the potential for in vitro three-dimensional high-resolution holographic images of dynamically varying biological microstructures.

X Rays and X-Ray Regulations

2010
The regulations on the handling of X rays are very similar to the regulations on standard radiation protection. The X-ray regulations in the European Union apply to those X-ray tubes and X-ray installations in which electrons are accelerated at least to 5 keV and in which they are limited to a maximum energy of 1 MeV.
