Particle accelerators reveal the heart of nuclear matter by smashing together atoms at close to the speed of light. The high-energy collisions produce a shower of subatomic fragments that scientists ...

A beam of electrons crossed just a few millimeters of plasma, then helped trigger an effect that usually belongs to massive research sites. In this case, the light produced fell in the extreme ...

Add Yahoo as a preferred source to see more of our stories on Google. An international team of researchers is pushing forward with plans for a radically smaller, cheaper particle accelerator by using ...

Scientists are unlocking new secrets of the universe with tiny particles called plasmons. These plasmons allow researchers to confine powerful electromagnetic energy within spaces smaller than a grain ...

Twenty-five feet below ground, SLAC National Accelerator Laboratory scientist Spencer Gessner opens a large metal picnic basket. This is not your typical picnic basket filled with cheese, bread and ...

Deep beneath the border of France and Switzerland is the most massive, most ambitious experiment ever undertaken by humanity. The Large Hadron Collider (LHC) is a particle accelerator that uses a ...

Particle and high energy physics seeks to understand the fundamental constituents of matter and the interactions that govern them across the smallest distance scales and highest energies. The Standard ...

Traditional particle accelerators, including radiofrequency linear accelerators and synchrotrons, have pushed physics forward for decades. They are also expensive, physically large, and limited in how ...
