First light for the pioneering SESAME light source

At 10:50 yesterday morning scientists at the pioneering SESAME light source saw First Monochromatic Light through the XAFS/XRF (X-ray absorption fine structure/X-ray fluorescence) spectroscopy beamline, signalling the start ...

New devices to control X-rays are less expensive, faster to make

Researchers at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have developed a less expensive and more efficient way of controlling x-ray beams used to study the intricate details of batteries, solar ...

Vortex photons from electrons in circular motion

Researchers at IMS and their coworkers have shown theoretically and experimentally that a high energy electron in circular/spiral motion radiates vortex photons from the radio wavelength to gamma rays. This greatly broadens ...
