ALICE's superconducting linear accelerator accelerated electrons to 99.9 percent of the speed of light, creating a beam with a total energy of 11 million electron volts
The most important radioactive-decay lines of astrophysical interest lie on the lower edge of Integral's energy range, between 0.5 and 5 million electron volts
(MeV), according to James D.
Washington, Nov 18 (ANI): UK's next-generation particle accelerator, ALICE, has achieved a major milestone by producing a high-energy particle beam with a total energy of nearly four and a half million electron volts
Their energies range from about 10 million to 100 million electron volts
, which means they're moving very fast but still far below the speed of light.
The missing energy would amount to about 1 million electron volts
, which is twice the rest mass of an electron, and would be a telltale signature of the mirror universe, Gninenko asserts.
But its energy range, from 5,000 to 30 million electron volts
, overlaps the low-end range of GLAST's Large Area Telescope to permit bursts seen by the latter to be compared with the database of bursts previously recorded.
Until an unexcited nucleus gains about 2 million electron volts
(MeV) of energy, theories predict, its nucleons should orbit in well-defined pairs of identical particles.
To produce the latter, the electric fields above storm clouds would have to accelerate electrons to energies of a million electron volts
, making them some 30 times more powerful than the fields normally associated with lightning.
These emissions, with energies between 3 million and 7 million electron volts
, appear to result from the bombardment of hydrogen and helium atoms by low-energy cosmic rays, chiefly carbon and oxygen nuclei.
A year's worth of observations by the satellite's Energetic Gamma Ray Experiment Telescope (EGRET) were combined to produce this false-color view of the cosmos at energies above 100 million electron volts
. Diffuse emissions from the Milky Way run horizontally across the map, which is shown in galactic coordinates with the galaxy's nucleus at center.
This is as far beyond low-energy gamma rays of 1 million electron volts
as those are from the near infrared.
The instrument counted photons with energies greater than 100 million electron volts
, produced when high-energy cosmic-ray particles (electrons and atomic nuclei) collide with interstellar material.
