Indeedy. We're all awaiting it - which is why I'm up waiting for data to look at, and not tucked up in bed.Xymox wrote:Different subject... From the CMS Page "gather the experts in preparation for the first physics fills of the LHC."
I think its approaching time...

I think I trust the Status Op page more on this. I've seen it cut out before if data is lost but not drop so I'm guessing the drop is accurate.Texanguy wrote:weird, eh? ._. or am i just missing something?DCWhitworth wrote:Yet page 1 still shows beam on at 1.22e+10Texanguy wrote: yeah, i noticed its intensity drop like a sack of bricks on the BRAN count rate chart..
This makes it clear now.Beam 1 with 4 bunches was kept for 45 minutes and then dumped. LHC page 1 is stuck again (LHC is working on
fixing it).
I think it's an error in the display system (as opposed to an error in the LHC workings)Texanguy wrote:Page 1: Global Beam Permit=Except? what does that mean? ._.
Definitely more attention. Man has appeared with video camera to film the moment . . .DCWhitworth wrote:Beam 2 circulating. More people paying attention at ATLAS now. . . .
