Some of the X-ray radiation circulating in the cavity is allowed to escape downstream, providing a beam of monochromatic and coherent X-ray pulses. They have called their system X-ray Free-Electron ...

Researchers have uncovered how atoms subtly rearrange themselves for up to a trillionth of a second before releasing low-energy electrons after X-ray excitation.

A team of engineers and scientists has shown for the first time that a hard-X-ray cavity can provide net X-ray gain, with ...

Together with an international team, researchers from the Molecular Physics Department at the Fritz Haber Institute have ...

TPU researchers have developed a mathematical model that accurately describes how Cherenkov radiation propagates in an exotic ...

Techniques that exploit the phase of X-rays, not just their absorption, have the potential to transform X-ray imaging in hospitals, reports Jude Dineley Improved imaging Marian Willner from the ...

Modern biomedical research depends on the ability to see what is happening inside biological tissue. Among the available ...

“Space is big. Very, very large”, Douglas Adams has once written, and interstellar comet 3I/ATLAS has made that famous statement look like a practical challenge to space vessels: how to scan the ...
