The copper target was operated at voltages of 11 kV, 12 kV, 13 kV, and 14 kV for the electron source, and a 50 kV configuration using a molybdenum target was used as a representative example for the ...

Images and spectra—charts showing the distribution of light across different wavelengths from an object—are the two main ways astronomers investigate the universe. Images tell them what things look ...

The X-Ray Imaging and Spectroscopy Mission (XRISM) isn’t the first of its kind, but the state-of-the-art spectroscopic instruments onboard have opened new doors for high-energy astrophysics. Active ...

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 X-ray pulses being circulated between crystal mirrors and amplified in the ...
