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 ...

The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

Alex Bogacz, a senior scientist at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility since 1997, has spent his career in accelerator physics solving problems. From ...

Particle accelerators smash tiny particles together to reveal the universe's building blocks. These machines have grown dramatically in size and power over time, leading to major discoveries. The ...

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 ...

Scientists have successfully developed a pocket-sized particle accelerator capable of projecting ultra-short electron beams with laser light at more than 99.99% of the speed of light. To achieve this ...

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 ...

Scientists have succeeded in creating an experimental model of an elusive kind of fundamental particle called a skyrmion in a beam of light. Scientists at the University of Birmingham have succeeded ...
