2014年4月28日 · Let us start with eV (electron-volt). It is an energy unit used in High-energy physics. A MeV is the Mega electron-volt, e.g. million times more than eV. One eV is defined as the energy, that an electron ( or an other single-charged(q=1.6*10^-19 Coulombs) particle) gains when it undergoes a potential difference of 1 Volt.

2014年4月28日 · In order to create an antiproton you have to accelerate a proton to very high energy and slam it into a metal target. Fermilab's Main Ring (synchrotron ring) accelerates protons to 120 GeV of energy. An eV (electron volt) = 1.6 x 10-19 Joules of energy, a very small amount. A (Giga-)ev or GeV is 10 9 or a billion eV. A (Mega-)ev or MeV is 10 6 eV.

2001年2月23日 · For a 10-volt battery, the proton gains 10 electron volts, or 10 eV, as it accelerates between the plates. Putting many power supplies ("batteries") in a row, physicists have accelerated particles to millions of electron volts (MeV). More powerful accelerators

MeV (Mega-electron Volts): 10 6 electron volts. MiniBooNE (Mini- Booster Neutrino Experiment): This experiment, based at Fermilab, represents the first stage of the BooNE experiment. It is searching for oscillations between muon and electron neutrinos. If an encouraging signal is seen at MiniBooNE, construction of BooNE will proceed.

2002年1月15日 · The Tevatron receives 150 GeV protons and antiprotons from the Main Injector and accelerates them to almost 1000 GeV, or one tera electron volt (1 TeV). Traveling only 200 miles per hour slower than the speed of light, the protons and antiprotons circle the Tevatron in opposite directions.

In the News: Stalking the shadow universe. From The New York Times, July 16, 2014. For centuries people have found meaning — or thought they did — in what they could see in the sky, the shapes of the constellations echoing old myths, the sudden feathery intrusion of comets, the regular dances of the planets, the chains of galaxies, spanning unfathomable distances of time …

2014年4月28日 · The electrons are accelerated to an energy of 75,000 electron volts. This is about the energy of the electron beam found in a television picture tube. This done at Fermilab in a machine known as a Cockcroft-Walton. The negative ions then enter the Linac or linear accelerator and are accelerated to an energy of 400 million electron volts.
