Using beam weapons to zap ballistic missiles has been a dream since Ronald Reagan’s “Star Wars” initiative. Now the U.S. Missile Defense Agency is looking for technologies that will enable space-based ...

In 2016, the European Organization for Nuclear Research (CERN) approved the high-luminosity large hadron collider (HL-LHC) upgrade project. LHC is currently the largest and most powerful particle ...

James Benford presents his Ultrahigh Acceleration Neutral Particle Beam-Driven Sails at Space Access 2019. The Neutral Particle Beam-Driven Sails could enable an interstellar probe to alpha centauri ...

Shaping up: A new machine learning algorithm helps physicists reconstruct the shapes of particle accelerator beams from tiny amounts of training data. (Courtesy: Greg Steward/SLAC National Accelerator ...

Whenever SLAC National Accelerator Laboratory's linear accelerator is on, packs of around a billion electrons each travel together at nearly the speed of light through metal piping. These electron ...

When a beam of energetic electrons travels through a plasma, the space charge at the tip of the beam knocks electrons from the ions in the plasma, leaving the ions with a larger positive charge. If ...

Defense officials are taking a step back from one of its most ambitious research goals: launching a massive neutral-particle-beam generator, essentially a ray gun, into space to fry the electronics of ...

There have been many discussions on our page (and many other science websites) about the matter vs. anti-matter debacle in recent times. Most of the time, these topics seem pretty far from the realm ...

The world's cutting-edge particle accelerators are pushing the extremes in high-brightness beams and ultrashort pulses to explore matter in new ways. To optimize their performance -- and to prepare ...

Many advances in medicine and drug development were possible owing to flow cytometry, a single-cell analysis technique that analyzes cells using the emitted fluorescence of their chemical tags while ...
