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

Physicists have now demonstrated a particle accelerator so small it fits inside a single molecule, shrinking one of science’s most imposing machines to the scale of chemistry. Instead of ...

There is technology being perfected to make particle accelerators 100-1000 times lower cost. This would enable production of nuclear material for space propulsion that could reach up to 0.5% of light ...
