Particle accelerators are often framed as exotic machines built only to chase obscure particles, but they are really precision tools that use electric fields and magnets to steer tiny beams of matter ...

In 1820, Hans Christian Oersted gave a demonstration on electricity to a class of advanced students at the University of Copenhagen in Denmark. Using an early battery prototype, he looked to see what ...

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 ...

The phenomenon of crystal channeling, whereby charged particles are guided along the interatomic corridors of a crystalline material, continues to yield transformative advances in particle beam ...

Physicists at the world’s largest atom collider have observed three new exotic particles as they continue to search for clues about the mysterious forces that bind subatomic particles together, they ...

A beam of electrons crossed just a few millimeters of plasma, then helped trigger an effect that usually belongs to massive ...

Some of the most fundamental questions about our universe are also the most difficult to answer. Questions like what gives matter its mass, what is the invisible 96 percent of the universe made of, ...

Particle-beam spectroscopy is a class of analytical methods in which a focused beam of charged or neutral particles (e.g., electrons, ions, neutrons) is directed at a target to probe its electronic, ...

Laser physicists have built a novel hybrid plasma accelerator. Particle accelerators have become an indispensable tool for studies of the structure of matter at sub-atomic scales, and have important ...
