Event pictures!! September 10, 2008

Lots of event pictures are available from the CMS web site specifically designed to comment on the activities going on today.

For instance, in the graphical display below, you can see the energy deposited in the calorimeter system (in blue) from beam-induced debris. The directionality of the energy flowing through CMS is obvious.

Check the others out here, where continuous updates are given.

[…] So the LHC got switched on. Its got some good publicity on the Internut. Right now the latest post by Quantum Survivor is the WordPress “Hawt Post” and the Google front page has a cartoon of the LHC !! My […]

Hi Rajendra, thank you for visiting.

Happysphere, that’s because you did not get the right glasses.

Scott, thanks for visiting.

Hi Tomasso,

Can you tell me when the LHC is expected to have accumulated 10fb ^-1 of data? How about 30 etc? I’m sure I saw a graph of this information once but now I can’t find it.

Hi Vlad,

no, actually precise LHC schedules are not available as far as I know. I mean, I have seen some graphs myself, but the schedule is constantly revised, so I think it is useless for practical purposes.

In any case, a ballpark estimate is not too hard to make. Before the winter 2008, estimates are between 5 and 40 inverse picobarns (at 10 TeV), most likely around 15/pb (the machine has done better than expected during this first week). Then, in six months of 2009 running, one might reasonably expect about 10 Ms run time, times a few 10^33 cm^-2 s^-1 = a few fb-1. Probably by the end of 2010 we’ll get well past 10/fb but I would think it far-fetched to hypothesize 30… I think estimates of this kind are really difficult, anyway, so of limited use.
