LHC portal

Hi there,

I don't think this link has been posted yet, so I give it here: http://cms-service-lumi.web.cern.ch/cms ... erview.php

There's a similar one for ATLAS, if you want I'll post it as well...

Enjoy!

Does anybody know why they witness such a drop in instantaneous luminosity (50% in a few hours), where the beam intensity stays nearly constant?

Nearly every day, just have a look at the "coordination" page on the vistars...

By the way, new record today, they've just broken the 3e30 barrier!

High intensity stable beams in progress!!!!

I see a 2.5e29 /cm²/s right now!

The LHC team has really done a great work in order to establish high intensity stable beams so fast!
I hope they'll be able to increase the number of bunches just as fast!

Thanks for you info, I would just like to say that i would never dream of saying i understand something and i would never say i was anything like a Scientist or a physicist because it's something i will never now or ever be.....popular science is a great thing to want to learn about, i have only be...

Hm what do you want exactly? Are you looking for "popular science" books or rather something formal? In the one case I can't recommend enough the "Nature of Physics" by Feynman, "The Elegant Universe" by Greene, "A Brief History of Time" and "The Universe in a Nutshell" by Hawking, "The Cosmic Lands...

What's the unit of the integrated lumi? (pb)^-1? Haha slide 2 made me laugh... "It's a lot easier to inject a lot of high intensity bunches into an equation than into a particle accelerator" :D I have a question... When they say "separation on", they do actually mean the beams don't collide don't th...

So they even have plan changes planned? :D If you have a change of plan planned is it still a change of plan ? :crazy: I'd say yes, as you don't know yet what you're gonna change ^^ (In a railway station not far from here, they have a special board with the planned delays of train departures ^^ Don...

poor kids!

Very nice, thanks!

I like the plot on the 7th slide from the ATLAS status report: male/female age distribution of the collaboration ^^

Nice!

The narrator also made a very beautiful vid about the hubble ultra deep field...

By the way I found this some years ago: http://casa.colorado.edu/~ajsh/schww.html

It's a bit old but well explained

Hmm maybe that's why we don't hear from our friend ivan anymore ^^

He's there, in Switzerland, trying to slow down the LHC operations!

I'm out XD

Well the fact is the LHC is roughly 100m under the ground... You'd need a hell of a big TV to be able to cause any disturbance...

Plus, the frequency of the hump varies, which would not be if it came simply from some regular apparatus above the ground.

There we go! The LHC is back online!

The experiments are headingfor a busy weekend: 3 days with 13 bunches/beam...
