The LHC will soon begin launching two beams with a power of 4 tera electron volts each
The Large Hadron Collider (LHC) in Sarn in Geneva began operating in "stable beam" mode starting on April 5 and continues to accelerate. The LHC experiment needs stable beams to collect data for physical analysis.
In its first six days of operation this year (in winter the accelerator, which receives its electricity from France, is inactive to save energy), it has already reached a brightness of 0.2 inverse femtobarns – a measure describing the performance of the accelerator equal to about 20 trillion collisions in the experiment. Last year it took six weeks to reach the same figure.
The number of protons sent in the facility - currently 624 proton bunches per beam, will increase in the coming weeks to 840, then to 1,092 and finally - 1,380 bunches, the maximum this year. The number of protons per bundle will also increase.
This year the protons will be launched at a power of 4 tera electron volts per beam, compared to 3.5 tera electron volts in 2011). And as a result, the large number of collisions will expand the detection capacity of the facility, and will open up possibilities for searching for new and heavier particles, the most famous of which is the Higgs boson.

Is it possible to get a reference to the data published by Saran?
Big particle, big trouble
Ehud, thank you very much.
Ori,
As far as I know from the newspapers, the maximum power that the accelerator was designed for is almost double, it is an energy of 14 tera electron volts, while today the accelerator reaches 8 tera. On the other hand, possible signs of the Higgs have already been discovered, so there is almost no point in increasing the energy, but many collisions with the relevant energies of 7-8 tera electron volts must be produced.
At what percentage of maximum power is the accelerator currently operating? And when is it supposed to reach its maximum power?
Thanks.
