CERN LHC Reaches Its Goals For 2010
Anonymous Dupaeur writes "The goals for the first run of the most powerful particle collider (and the most energetic storage ring since ISR) were recently surpassing the 10^32 level of luminosity, with a destructive 15 MJ energy per-beam. This is a significant milestone, opening the way to collect more and more data. The current plan is to stop the proton collisions soon, and provide an ion (Pb) beam and conclude this year with a X-mass break. The next year is expected to bring at least one inverse femtobarn of data, which is achievable with such beam power. After that, the entire accelerator complex will be shut down for a year, due to budget costs for science in Europe."
conclude this year with a X-mass break.
Is that supposed to be some kind of punny joke?
The cost is too high to run next year. That is disappointing.
So you editors are going to go ahead and just post any old gibberish?
The next year is expected to bring at least one inverse femtobarn of data, which is achievable with such beam power.
Provided the inverse femtobarn doesn't react at a quantum level with the inverse tacheons (they're BOTH inverse!) then we should be fine.
I hope someone has thought of the possible interactions here.
wtf is a inverse femtobarn? Great term though
.
Summary is incorrect. The LHC is NOT shutting down due to budget cuts. It was planned to shut down to accommodate the upgrade to full 7TeV beams. The budget cuts are responsible for shutting down other accelerators (not LHC). If you can even name one of these other minor accelerators, you know more about CERN than I do (and IAAPP).
Have they used the Large Hardon Collider to make a black hole yet?
Everything still seems to be here, so I was hoping they tried it and everything went well.
they'll have to take the femto-hay out to make room for all that data.

Actually, it's only 14.9999999.... MJ, so we're safe. Thank goodness!

That is the holiday where they suppress the higgs field causing the destruction of the universe. Which is not so bad if it stops those fruitcakes from being delivered.
Were recently ... "achieved/reached" ... surpassing. Someone please edit that.
The article says 2012. Is it 2011 already? Did my nap take THAT long???
But Earth still exis
In the future you will be able to buy reproductions of tacky watercolor paintings depicting landscapes with inverse femtobarns. Will they have a weathered texture to their walls? Will they be colorful or drab? Will they be upside down? Will they sell them at Ikea?

Wait, are they trying to study particle behavior or build a Death Star?

One inverse femtobarn of data? Is that the euphemism they're using nowadays for "one shitload of data"?
You mean creating an Earth swallowing black hole wasn't on their list of goals?
The summary didn't mention how many MeV's the particles had. Is it that they weren't colliding the beams?

You do realize that "Budget cuts force CERN to shut accelerators for year" is yet another example of the God particle coming back in time and preventing its discovery. Indeed I'd wager that this entire "Great recession" is do to the God Particle's insistence on anonymity. That or the theory that in this universe the CERN collider cannot operate else a black hole would open and swallow us all.

* LHC did not explode into bits.
* finally find the other side of that wormhole (spills out into a closet in it).
* 30 consecutive days of no spontaneous human combustion.
* Do not destroy the galaxy with spurious black hole generation.

....to get the total number events that you should see.
Actually that gives you the number of event that should be produced. The number that you should see also depends on your detector's acceptance and efficiency.
Don't forget to remove the Beam from thine own eye before removing the Mote from thy neighbours eye.
I took out the Mote in Gods Eye once.
Borrrowed it from the library, a great read.
to restart it on December 12th, 2012. Yikes!
The earth hasn't been swallowed by a man-made pinpoint black hole yet!
Isn't LHC supposed to destroy the universe by creating some black holes? It'll be very disappointing if the 2 billion investment for LHC will not even destroy the universe. If I were putting my money on it, I would immediately want them back.
Right.
But the note correctly states that "entire accelerator complex", and not just LHC. If you could attend the meeting when the DG was announcing this, you could easily understand that the saving on the electricity due to the LHC's shutdown will help a lot to cut the budget. So now, only for 2012, but who knows what will happen next?
The upgrades (of LHC!!) were already postponed. For example LINAC4 and new SPS were postponed, the same will happen to PS. Perhaps PSB will be more lucky...
That translates to two days' caloric intake for a sedentary worker.
It is very interesting that over the years the bar for "success" has steadily lowered for LHC. Right now, with this press release, they are years behind their initial schedule and around 1 order of magnitude behind the "obsolete" Tevatron collider run by the Americans. At this rate, Tevatron will have the Higgs long before LHC. There is something to be said for a little pressure (just a little) to encourage hard work and efficiency in science. It has worked wonders for Tevatron. LHC, with a (giant) secure budget and no competition on the horizon lacks a certain urgency one generally finds in scientific research. When one experiment commands more funding than many entire scientific disciplines you end up with some strange things. One day, we'll hear publicly about the first class plane flights, the catered lunches and the unusually soft work schedules, but for now... bringing such things up is forbidden.
Yes, this is anonymous, I'd like to keep my job. Criticizing the LHC is about the worst career decision for a physicist outside of espousing geocentrism.
As in, "Give us money or we'll point our giant particle accelerator at your country and give you all cancer!" Evil laugh is optional...
I'm trying to teach myself to set people on fire with my mind... Is it hot in here?
They should just turn it up to whatever the full power is and answer the question about the "higgs boson" once and for all...
