3.5 TeV accelleration ! WORLD RECORD !

Post by Xymox » Fri Mar 19, 2010 4:45 am

Records were smashed tonight when the LHC reached 3500GeV per beam. :scared-shocked:

Congratulations :happy-jumpyellow: to all of the LHC team and CERN...

Now on to collisions at 7TeV...

Exciting times...

Congrats :dance: CERN and LHC guys,girls :thumbup:

Can't wait for the collisions :thumbup:

Haven´t they already collided the beams? Since both beams were running a 3,5 TeV at the same time?

Yeah!
We can now hope for a few "accidental" collisions, but maybe they will delay the news for a good publicity moment.

So since both beams were ramped up to 3,5 TeV at the same time, have the beams technically collided?

I don't expect accidental collissions as long as they run both baem with only a few bunches.
The more they fill the ring with more bunches of protons accidental collissions will be more likely and I really don't belive they try to avoid them.
Nevertheless its interesting that the LHCb-detector appears in off-mode for a long time now since this one was the first one to show early collissions to the public in december.

Hi

At present the bunches are placed in the machine in such a way that they do not collide in the experiments. Imagine 2 cars driving in opposite directions around a racetrack. They will cross in 2 diametrically opposed locations. The LHC can arrange it so that these crossing points occur outside the experiments. This way they check out the settings of the machine for both beams together without the added complication of them colliding - that comes later.

Correct so far, only that htere are no crossing points outside the experiments onlypassages of bunches wich never meet.

It won't be too long before we see actual collisions.

They plan first collisions for 30th press conference or whatever are they planning to hold that day.
Technically speaking, half-energy (1.75 TeV) collisions are already happening (with residual particles in beam pipe, with beam pipe itself and in dump), yet another world record. It just doesn't happen in experiments.

Dont you think they will do some before? It would be embaresing if it did not work.

I don't think they can top the embarrassment they had in 2008 or when that bird dropped bread on the machine.

Each beam is 3.5 TeV, so total collision would be 7 TeV (with half being 3.5, not 1.75) - full power is 7 TeV and 14 TeV respectively.
