This is bunny and friends. He is fed up waiting for everyone to help him out, and decided to help himself instead!
It's partical physics which is (probably) going to give us the best solutions for replacing our crude, fossil burning technologies.
Either that or wipe out the world and possibly the universe in an instant.
Either way, let them have their fun with their giant frikkin laser.

Some very interesting pictures there, thanks. No. 12 (with all the magnetic tape) particularly caught my attention - how much data (in terabytes/petabytes) is the LHC expected to produce when running properly?Originally Posted by Fraz
Yeah, that system is called CASTOR. It's good and bad. In certain circumstances, you can certainly be waiting for quite a while for your data to be staged on the hard-disk front-end. I guess that's pretty unavoidable though.
Raw data alone - i.e. before it gets turned into more useful physics analysis objects - the CMS experiment that I'm working on will be producing about 10 peta-bytes per year. Once you factor in converting the raw data into more useful formats, add on some Monte-Carlo simulation data, and then some data duplication to 2 or 3 other large centres (such as Fermilab), it'll be pushing 100 peta-bytes per year.
The ATLAS experiment will be producing about the same amount. I'm not sure about the two other smaller experiments, LHCb and ALICE, but let's call them about 100 peta-bytes together.
So... ball-park, the LHC experiments altogether will be producing about 300 peta-bytes of data per year, and we'll be running for about ~10 years before we upgrade things. So, for the lifetime of all current LHC-related CERN experiments, I guess the total dataset will be in the region of 3 exa-bytes.
That's a lot of data to be in one place... any backup ?
or is that the data duplication with fermilab?
Your all missing the main point, and the important point..think of the amount of PORN you could store!!That's a lot of data to be in one place... any backup ?

It didn't fall off, it merely became insufficient at it's purpose and got a bit droopy...

There isn't enough porn in the world!

nope

Yes, data duplication with other major data centres, such as the one at Fermilab. Basically CERN forms the "Tier 0" data centre, where one copy of the entire dataset will be stored. There are then a number of "Tier 1" data centres, such as at Fermilab in the US and the Rutherford Appleton Laboratory here in the UK. Between all these Tier 1 centres, the data will be duplicated, but not all of it at any single Tier 1 centre. Then there are Tier 2 centres at various universities, which again between them duplicate all the data at each Tier 1. So, it should be fairly safe.That's a lot of data to be in one place... any backup ?

Better get humping (and videoing).
You sooo underestimate the amount of porn out there...

The LHC is now officially the highest energy accelerator in the world, after breaking the previous record in the early hours of this morning:

Congratulations Gordon.... er...Fraz

May I suggest a large pile of empty cardboard boxes, neatly stacked with an old matress on the top?
Every stuntman in the world knows how effective that is for catching their beer and paracetemol swollen bodies at the bottom of a 5 floor fall
Oi Fraz!!!
That is all.

Congrats Fraz et al
Now, *try* not to vaporise most of the franco-swiss border, at least not this side of Christmas, it does vex people when that happens
