"A few minutes ago, one of the beams of the LHC was ramped up to an energy of 1180 GeV, besting the Tevatron’s top beam energy of 980 GeV.

 

Update: Actually the beam was lost at 1070 GeV, which is still a record high energy."

 

==========================

 

An update says that they now have gotten each beam up to 1180 GeV. It also gives a figure for the brightness (how many particles fly past per second).

 

So with two beams each at 1.2 TeV they could be looking at collisions with a total energy of 2.4 TeV. Already this is somewhat higher than what has been produced at the older Fermilab collider---the socalled "Tevatron".

I posted the official 'update' on this in the news thread.

If I am hijacking this thread, I apologize, but since there are already threads about the LHC I didn't want to start another. I have two questions about the "beams" circulating in the LHC. Firstly, I have heard the path followed described as being a spiral, is this true even when no collisions are being done like during stability tests? Secondly, how long can the beam be held stable before substantial decay sets in (last I heard was about 10 hours) and will it ever be possible to maintain it indefinitely?

 

Well, maybe that was three questions, but then math was never my strongest subject.
