This has been a great 24 hours for the LHC. Now the systems commissioning begins, so we’ll be tweeting less often for a while.

Nice animation of a beam splash in the LHCb experiment. Look at their page:

Welcome back beam 1! This is the clockwise direction:Point 2(ALICE experiment)->3->4->5(CMS)->6->7->8(LHCb)->Point1 (ATLAS).Its' circulating

Were you looking for an animation of the various steps I am describing? From bottle to bang:

Yes,the trick is the concentration of energy in tiny tiny tiny tiny particles.Now,let's move to step 5: particles enter the LHC

RT @: ALICE experiment records splashes as well!

Back to450GeV,the extraction energy from SPS.Crushing a nut easily involves more than 450GeV of your energy.So,where is the trick?

4 step: protons are sent to SPS, the last circle before the LHC.A few turns to increase the energy up to 450GeV. Do you know how much is it?

3rd step: protons are sent to circular accelerators (PSB and PS): it's were bunches are prepared. The energy increases. And then..

In reply to some tweets:there is no issue with any single dipole at LHC.Teams are simply improving the calibration of the protection system.

2nd step: protons are accelerated in a LINAC=linear accelerator. Their energy starts to increase. And then...

Some info about how we make beams for the LHC:protons are produced by stripping electrons from hydrogen atoms.This is easy.Then..
