  3. Particle accelerator that can fit on a tabletop opens new chapter for science research

    The laser plasma accelerator has accelerated about half a billion electrons to 2 gigaelectronvolts over a distance of about 1 inch. It's a downsizing of a factor of approximately 10,000, and marks a major milestone in the advance toward the day when multi-gigaelectronvolt laser plasma accelerators are standard equipment in research laboratories around the world.
