article_snippet.sent: Scientists in California said a particle accelerator could be sent 185 miles (300km) up into space (illustration of a satellite in orbit shown).
article_snippet.sent: a particle accelerator would then fire high-energy beams back at Earth's atmosphere .
article_snippet.sent: a particle accelerator would be three times stronger than anything like a particle accelerator before, producing a beam with particles 0.5 to 10 million electron volts.
article_snippet.sent: Pulses of a beam would last just 0.1 microseconds.
article_snippet.sent: a particle accelerator would be located in space, 185 miles (300km) above the ground, and would fire back towards Earth's atmosphere.
