Very nice run today, 10hrs + @ 3.5TeV and still going! I think this would be another record. Lots of fireworks in the experiments too!

Can't believe it, the 12 performance graph on the LHC_OP page is about to have a straight line all the way across!

Wowa! Over 14hrs now and counting!!! They up'd the bar and set the graph for 18hrs but heck, looks like thy might make it!!

Defiantly a record.

If I were them I would just let it run...

Good burn in for all the equipment... Good test for everything...

AND great for the experiments... After that last 3-4 days of oopsies...

from this mornings progess report -
Plan for the day:
Keep this fill depending on luminosity lifetime. Experiments to tell us

Well I don't think they made 24hrs, but it looks like they got past 18hrs which is certainly a record. The collisions from ATLAS look great.

Congrats again to Cern! :thumbup:

I've just checked the LHC status screen 1 and there's the energy set to 7864 GeV. Is it a test of the maximum energy setting or just some nonsense? I thought that the 2x7 GeV collisions will require major reconfiguration of the whole device after the 2x3.5 burn in.

Anyway, I was watching the 18+ hours run on the public pages and it was fascinating.

its just the software that that's all, the machine needs re-wiring for 100% safe 14TEV runs

It defaults to that number when in one of the modes - Access I think.

Looks like another good start, beam for almost 1hr and ramping now. Wish'em luck for another long run!

2 hrs+ uptime and flattop on P1, looks like a good run start for sure.



Harbles, could not get the cms link to work- overloaded?

Hope they go all day!
