Densitometer system for liquid hydrogen has high accuracy, fast response [PDF]
, 1966 Developmental densitometer system for cryogenic liquids uses two balanced ionization chambers containing xenon gas, with X rays as the radiation source. The X rays are heavily filtered with a lead shield to make the energy spectrum much less dependent on

Design of laser-electron storage ring lattice dedicated to generation of intense X-rays under Compton scattering [PDF]
arXiv, 2004 The lattice of laser-electron storage ring with controlled momentum compaction factor dedicated to generation of intense X-rays under Compton scattering is described. In such storage ring one can achieve the large energy acceptance and keep the long-term stable motion of electron beam with large energy spread. The intensity of X-rays may be very stable

Raios-x: fascinação, medo e ciência X-rays: fascination, fear and science
Química Nova, 2009 This work presents the discovery and the use of x-rays at the end of the XIXth and the beginning of the XXth century. X-rays greatly impacted science and everyday life. Their existence broke the idea that knowledge had reached a limiting step. In general,

Spectral Brilliance of Parametric X-rays at the FAST facility [PDF]
arXiv, 2015 We discuss the generation of parametric X-rays in the new photoinjector at the FAST (Fermilab Accelerator Science and Technology) facility in Fermilab. These experiments will be conducted in addition to channeling X-ray radiation experiments. The low emittance electron beam makes this facility a promising source for creating brilliant X-rays.

Electron beam welder X-rays its own welds [PDF]
, 1967 Beam of an electron beam welder X rays its own welds, enabling rapid weld quality checks to be made without removing the work from the vacuum chamber. A tungsten target produces X rays when hit by the beam.

A study on role of chest X-rays in children above 5 years admitted with asthma exacerbation
Muller Journal of Medical Sciences and Research, 2018 Context: Asthma is a heterogeneous disease characterized by chronic airway inflammation that causes airway hyperresponsiveness. The diagnosis of asthma is mainly clinical, and chest X-rays are not required for the diagnosis or grading of severity of ...

Coherent hard x-rays from attosecond pulse train-assisted harmonic generation [PDF]
, 2007 High-order harmonic generation from atomic systems is considered in the crossed fields of a relativistically strong infrared laser and a weak attosecond-pulse train of soft x-rays. Due to one-photon ionization by the x-ray pulse, the ionized electron obtains a starting momentum that compensates the relativistic drift which is induced by the laser ...

X-ray phase contrast imaging of biological specimens with tabletop synchrotron radiation [PDF]
, 2011 Since their discovery in 1896, x-rays have had a profound impact on science, medicine and technology. Here we show that the x-rays from a novel tabletop source of bright coherent synchrotron radiation can be applied to phase contrast imaging of ...
