CMS has just recorded the first collisions with stable beams at a world-record collision energy of 8 TeV[1].

LHC Glossary



TeV

A TeV is a unit of energy used in particle physics. 1 TeV is about the energy of motion of a flying mosquito. What makes the LHC so extraordinary is that it squeezes energy into a space about a million million times smaller than a mosquito.

TeV stands for tera electron Volts. That is 1,000,000,000,000 electron Volts or 1012 electron Volts. [tera - f. Gr.{tau}{geacu}{rho}{alpha}{fsigma} monster.]

An electron volt is an unit of energy, particularly used in atomic and nuclear processes. It is the energy given to an electron by accelerating it through 1 volt of electric potential difference.
The abbreviation for electron volt is eV.
Energies in electron volts


An adult female mosquito weighs only about 2.0 milligrams (about 1/15,000 ounce).

1 eV = 1.6 x 10-19 Joules

1 TeV = 1.6 x 10-19 x 1012 Joules = 1.6 x 10-7 Joules

1/2 m v2 = 1.6 x 10-7 Joules, m = 2 x 10-6 kg therefore v = 0.4 m/s = 1.4 kph


Apparently Mosquitoes can fly about 1 to 1.5 miles per hour. 1 mph = 1.6 kph so our mosquito is a little slow, but the comparison is a good one.

so what happens then if an accelerated particle collides with a female mosquito?

Hey, it's a Spirograph!

So will all this energy be able to charge my new iPad or not?

Nothing . The mosquito would have died before getting anywhere near the beam. Which is 100 meters underground. In a vacuum. At about 4 degrees Kelvin. Within some mongo multi Tesla magnetic fields .

LOL - I was thinking the same thing

I wonder how many digits are in their electric bill.

about 10^12
