CERN has announced that it’s going to boost the beam energy of the Large Hadron Collider by 0.5 TeV this year in a bid to pull more data out of the micro-universe before the machine takes a break at the end of the year. The CERN management says running the LHC at 4 TeV per beam will help it meet a data target of 15 inverse …
Where's da Higgs at, yo?
> "full design power of 7 TeV per beam in 2015"
Sadly not. CERN seems to have settled for a maxout at 6.5 TeV for safety reasons. They don't want to risk blowing the interconnects, if I understand correctly.
And in particular, the summary of the Chamonix technical meeting [Not averse to skiing, are we?], here:
"DO NOT GO FOR 7TeV PER BEAM DUE TO THE RISK ASSOCIATED WITH MANY HUNDREDS (THOUSAND) QUENCHES - Around 6.5TeV/beam is safer and sufficient"

"They couldn't hit the broadside of a barn at this dist ..."
What I was going to say!
"In other words, how many barns are your particles going to hit?"
In more appropriate terms, what are the odds that your particles could hit a barn, i.e, broad side thereof?
If you're referring to the alleged famous last words of General John Sedgewick, the unit of measurement you require is the elephant...
Thank you, Mister Marsden. I know.
But we were discussing femtobarns, and there is an expression ... ah, hell. If you have to explain it, it's not quite as funny.
On the other hand, you live in a nanny state which has removed weaponry from the peons, so perhaps you've never heard the expression.
On the gripping hand, I vaguely remember "sheds" and "outhouses" being bandied about when I was working on the computers at SLAC.
"They couldn't hit the broadside of a barn at this dist ..."
Here we modified that to:
"They couldn't hit a barn if they were standing inside it."
With a femtobarn, this would create difficulties of course.
Call me when they crank it up to eleven.
But we need to know

Now I have a mental image of all the boffins sat at their desks playing femtofarmville on incredibly tiny portable devices.
used to house octohorses (a la Sleipner)?
Yes, I got it
"More power Igor!"
I really hope there actually is a wall of big old fashioned breaker switches, and they have a hunchbacked dwarf to pull them whilst cackling maniacally.
It won't really just be a person (not even in a white coat) tippy-tapping on a keyboard.
And they wonder why the lay-person can't connect with science...
Now Igor, while the storm is at its height!
Not forgetting the essential Jacob's ladder and the large wheels that can be cranked maniacally when required.
Computers may be efficient, but they just don't have the visual appeal of a brain in a tank.
We must have Blinkenlights!
Actually, in the original 1931 Frankenstein...
...the assistant was actually called Fritz. And in Bride of Frankenstein, he was Karl, apparently - played by the same actor. (Even though the Monster killed Fritz in the first one...)
Don't know when Igor became the norm...
Dilithium crystals, we need some dilithium crystals
But the question we ask ourselves
How many femtobarns in a nano-wales?
2.78*10^44 Femtobarns in a nanowales
I remember a load of stories before Xmas about how they'd almost found Higgs and it was only a matter of time.
Now they're cranking up the juice...does this press release come under the "errr, oops. Nothing here afterall. Maybe we better keep looking" heading?
Plus that whole 'breaking the speed of light' thing. All gone suspiciously quiet there. I reckon they've knocked up a time machine and are making a mint on the horses.
Well they will have had to have been going to have paid for all this somehow.
The increased energy is not the same as an increase in luminosity (measured in inverse femtobarns).
There's essentially two factors under control: Luminosity (or the NUMBER of particles in a beam) and Energy (or the "speed" at which they're travelling).
A la E=mc^2, only particles whose mass is lower than the Energy/c^2 can be created (mass-energy conservation). Increasing the energy opens up the mass range of the particles you can hope to observe.
Increasing the luminosity increases the number of collisions and therefore increases your hope of catching a rare event (like the Higgs Boson being generated). Now, they've already created a number of events which look like a Higgs, but they *could* be something else. I'm simplifying, but the idea is to generate more Higgs Bosons so that you're 99.9999% sure that it wasn't just something that looks like a Higgs. At the minute, they're *only* 99.95% sure that they've seen it, so they want a few more events to be sure.
Increasing the Energy gives us a higher chance of seeing something we're not expecting. We already know that the current theories will break down at a certain energy, so by upping the energy enough, *eventually* we'll make a massive breakthrough. Worth some tax pennies in my opinion.
If they have
They willen haven been winnened, and wollen be maken hay.
"running the LHC at 4 TeV per beam will help it meet a data target of 15 inverse femtobarns for the ATLAS and CMS experiments, with LHC bunch spacing to remain at 50 nanoseconds."
But what about the plasma phase inducers? Or the inertial damping field? Or the dilithium polarity reversers?
"Boffin" makes your article unworthy
Regardless of the content of your article here, it is marred by the fact that your use of the word "boffin" continues to reinforce a socially constructed stereotype of the scientist as a person who is an outgrouper from society that should be viewed with ridicule and contempt.
How banal your reference is, is irrelevant. It is just a reinforcement of a stereotype that needs to go away.
Unless you are trying to campaign to "take back boffin", don't use it.
Might I suggest a t-shirt? "Boffins do it better"? or "Boffins save the world!"... or similar.
I really don't understand this "anti Boffin" stance.
I have t-shirts that reference boffin. My coffee cup reads "Boffin at Large" on one side, and has a large familiar blue oval trademark on the other. Most of my race cars have had a 22"X10" stencil that reads "DANGER! Boffins at work!" for the last thirty years. I tried to get the CA State license plate "BOFFIN", but somebody already bagged it ...

And I'm a bloody yank!
