back to article LHC boffins crank beams to 3.5 TeV redline

Big news from the Large Hadron Collider (LHC) overnight. The titanic proton-punisher has once again smashed all records to achieve the most powerful particle beams ever generated by the human race, at energies of 3.5 Tera-electron-volts - the maximum redline power at which the mighty machine can currently be safely run. Slide …

So that's what happened!

"much the same as if HMS Invincible had suddenly popped out of nowhere"

So that's the origin of all those stories about time-travelling warships! When they switch it to full power the black hole it creates will rip open a gap in time.

It's obviously what the Philadelphia Experiment was based on.

Someone from the future got sent back in time and that's how the story started!

The Philadelphia Experiment?

Nah, it was "The Final Countdown" (1980) starring Dirk Kouglas.

7 TeV beams, which can be crossed

They really didn't listen to the safety advice in ghostbusters did they?

Special relativity fail

The energy in the beams, measured in GeV, really is the energy, not the velocity. Half the energy is half the energy. If the beam is at 3.5TeV rather than 7 it's still going near-as-dammit at the speed of light. Oh, and it's also proportional to the luminosity (brightness) of the beams - how many protons are in all the bunches. Which at this early stage is a tiny fraction of the maximum. The energy of a trundling Reliant Robin, perhaps.

Commentard Fail

The total energy in the beams is the particle energy in GeV (normally called the beam energy) multiplied by the number of particles. at 7TeV this equates to the kinetic energy stored in an aircraft carrier at 12 knots. Relativity does not apply to things whose speed is measured in knots, they were excused.

So, half the beam energy of 3.5TeV, assuming the same luminosity = number of protons, results in the aircraft carrier moving at root2 x 12 knots.

In full running condition, dozens of individual beams are packed into a square lattice within the beam cross-section, Im not sure how many of these they are running right now. This aspect of the machine is incredibly clever - how they cool down the transverse momentum of the protons so that they stay in tight 0.5mm beams for 100 hours. This looks to be working, as the screenshot suggests - and is worthy of another Reg article.

Keep up the good work.

Sounds complicated.

Has it become one of those French aircraft carriers that can't go very fast? Why is the aircraft carrier in a tunnel? Aircraft carriers are not supposed to ram things. If the Swiss fund their Navy to build aircraft carriers in tunnels, that might explain the current importance of the Swiss Navy. Should the Swiss rethink their naval policy?

Thank you very much.

Although I am sure some politician somewhere could give grant money to determine how to reverse the polarity of a particle without polarity.

Wow ..... that would be Tantamount to IT Performing Remote Miracles too, Tom Kelsall, and who would be Fool enough to Rule it Out, given what is Now Known about IT in ITs Remote Leading Circles and Circuses.

I would Fear for their Sanity though whenever they Realise the Damage they have been Doing to Themselves and Innocents, in the Name of Peace and Stability/Democracy and Capitalism .....which is surely their Madness confirmed.

I'm not convinced a chunk of 750 tonnes of concrete would stop a 12knot aircraft carrier?

750 tonnes of concrete AND...

a giant graphite sponge.. it works like a gravel trap where 4 tonnes of gravel can stop a 40 tonne truck (by creating 4 tonnes of grapeshot? and a 'ton' of noise). anyway The graphite converts the kinetic energy into something else, im not sure what but I do know that it is pretty radioactive and nasty.

Calm down Lewis

"unimaginably violent particle collisions at 14 TeV"

That's about 1 hundred thousandth of a Joule. Quite a lot for a single particle, but hardly unimaginable. A fart is several orders of magnitude more violent.

@Ken Hagan

Yeah. But we're not talking about a single particle, are we? We're talking about several billion of them in a stream travelling at nearly the speed of light. I don't, therefore, think you're being entirely fair.

RE: aircraft carriers - at 8-12 knots an aircraft carrier takes several football-pitch lengths to stop using its own engines. If one hit something solid at that speed the damage would be very, very serious.

Aircraft carrier analogy

Analogies are good when you have the relevant experience to picture the them in your mind. I'm struggling with how destructive an aircraft carrier at 8 or 12 knots might be though. Seen an Australian Navy Frigate plough in to Hobart harbour at a couple of knots at the 75th Royal Australian Navy celebrations in the 80's and that did a fair amount of damage.

Still, with the way Royal Navy commanders have been handling their vessels recently I suppose it's only a matter of time....

HMAS Melbourne

was quite good at stopping things, too; HMAS Voyager and USS Frank E Evans. And she was only a "light" aircraft carrier.

Why Struggling?

You have your own ballpark example right there. You just need to imagine a ship around 4 times as heavy at 4 times the speed (16x energy). A factor of 64 should be easy enough to imagine.

I have never seen a Frigate ramming a harbour, so I do indeed struggle with the analogy, but I will shortly be visiting YouTube to see what I can find :-)

Pah. How hard can it be?

I'm sure most of the Reg readership have dumped core at some point in their careers.

Figuring out why it dumped is usually *much* more difficult.

Not to question where the dump is located cos that may make things worse!!

Mini-carrier

The beams weren't at full intensity (only 'pilot'), a mere 5 x10^9 protons as opposed to around 10^14 for a nominal run.

So more like the aircraft carriers you bring at bathtime.
