It provides an extremely high precision of about 1.2 x 10-4 at a photon energy of around 18.6 keV. Compared to conventional spectrometers, it achieves a signal strength that is four to 22 times ...

Astronomers have traced a mysterious blast of X-rays to a star that, like a cosmic action hero, just refused to die.

High-energy X-rays leave a trace of destruction in bone collagen. ScienceDaily . Retrieved June 2, 2025 from www.sciencedaily.com / releases / 2022 / 12 / 221222101006.htm ...

A distant cluster of galaxies is wrapped in a vast halo of high-energy particles that could be the work of supermassive black ...

"The high-energy photons from the X-ray light trigger a cascade of electron excitations. Ionization of calcium and phosphorus in the mineral then damages proteins like collagen in bone," Sauer says.

A distant galaxy cluster has turned into a giant particle accelerator, spinning electrons over vast distances at high speeds. IE 11 is not supported.

When that happens, the electron gives the photon part of its energy, which ramps low-energy infrared light up to the high-energy x-rays and gamma rays that light up the black hole’s jets.

China is set to unveil its High-Energy Photon Source (HEPS) that will transform scientific research with high-energy X-rays. With an investment of $665 million, ...

High-energy clinical X-ray radiotherapy systems are typically based on a room-temperature RF linac that accelerates electron beams to the MeV level. These electrons then irradiate a target that ...

Scientists currently use high-energy X-rays to better look at atoms and molecules, giving us glimpses into how they are arranged. The researchers capture diffracted beams of x-ray light, ...
