The shower peppered the ground with io billion particles, and when it hit the atmosphere, it carried 20 to 40 billion billion electron volts. This made it by far the most powerful ray ever detected.

For reference, 1 exa-electron volt equals 1 billion gigaelectron-volts, and 1 gigaelectron volt is 1 billion electron volts. That would make the Amaterasu particle 244,000,000,000,000,000,000 ...

Researchers have demonstrated a compact particle accelerator less than 20 meters long that produces an electron beam with an energy of 10 billion electron volts (10 GeV). There are only two other ...

When they have been fattened to about 1 billion electron-volts (or 1 BEV, as physicists call it), they begin to radiate visible light. At 2 BEV, they radiate the more powerful ultraviolet rays.

Ruling out the pulsar’s radiation allowed the astrophysicists to see a source of even higher-energy gamma rays — 10 to 500 billion electron volts — somewhere in the middle part of the cloud.

The accelerator automatically stopped when it rose to about 540 billion electron volts, about 90 billion electron volts more than the energy at which the Large Hadron Collider has been operating ...

The USA has only two accelerators that can produce 10 billion electron-volt particle beams, and they're each about 1.9 miles long. "We can now reach those energies in 10 cm," said the CEO of TAU ...

And now there’s Vela, with gamma rays blasting out of its poles with 20 trillion electron volts of energy (and flashing us every 11 seconds as the pulsar twirls frantically on its axis).

The first observation of gamma rays with energies of more than a billion electron volts came from NASA's Fermi Gamma-ray Space Telescope in 2011.

Now, for the first time, the team has shown that the energies of the sun’s rays extend into the tera electron volts range, up to nearly 10 TeV, Nisa said. She noted that level does appear to be ...

Researchers from The University of Texas at Austin, several national laboratories, European universities and the Texas-based company TAU Systems Inc. have demonstrated a compact particle accelerator ...
