they are going to try and brake into the 1e10 32-1 luminosity range this week. this was the ultimate goal they set out for this year, and since they still have the rest of october left for physics there is a good chance they will have a higher luminosty than that!

It seems that while they are repairing the LHC someone has posted a picture onto Page1 ! :)

Saves looking at just the ACCESS NO BEAMS banner :clap: :)

Higher beam energy in 2011?

At the beginning of the technical stop in December there will be a meeting in Evian.
According to the linked document they plan to discuss higher beam energies between
3.5 and 4.5TeV.

Great, two really good runs in the last 24h!
They gathered approx. 8.8/pb so far and plan to dump at 14:00h, by then they will have surely collected 10/pb.

So they should get 50/pb till the end of proton physics even if there are a few problems.
If they would stay with 368 bunches and simply do fill after fill for physics they may reach
even 100/pb this year. I'm really curious if they go for higher intensities the next days.
I would simply do physics because they have to check many things again after the winter,
maybe there are some things they could commission for higher intensities in parallel.

Edit:
Here is the new schedule (on page 5):
http://indico.cern.ch/conferenceDisplay ... fId=111336
In short: They will do further development (50ns) but they want at least 40/pb.

i wasnt expecting anything untill next year this is excting news :) while on the subject of exciting, it might be worth mentioning that they are going to push for 400 bunches tonight! good luck guys i hope all goes well ;)

Yeah wow ! :D Things have been moving so fast recently. 400+ bunch fills, 32 bunch injections, record luminosities, I noticed a 2m squeeze in there somewhere. They're also talking about 50ns bunch trains and 4.5 TeV energies.

I look back and see where the machine was six months ago and it's been amazing progress. :clap:

I wonder if they'll create some gold, too... :whistle:
