Understanding how helical, curved beams operate — how their spiral cuts accommodate angular and parallel misalignment, axial motion, and system vibrations — is the key to knowing how they will perform ...

BUFFALO, N.Y. — In a physics first, a team including scientists from the University at Buffalo and the National Institute of Standards and Technology (NIST) has created a way to make beams of neutrons ...

If you shine a beam of light from a laser or flashlight, the beam will spread out over distance, becoming wider and less intense far from the source. That phenomenon is called diffraction, and it is ...

Bright idea: researchers in China have found a new way to accelerate electrons using pulses of light. (Courtesy: iStock/7io) A laser wakefield accelerator (LWFA) that guides its laser beams along ...
