Next on the schedule is an intense commissioning phase aimed at increasing the beam intensity and accelerating the beams. All being well, by Christmas, the LHC should reach 1.2 TeV per beam, and have provided good quantities of collision data for the experiments’ calibrations.

1.2 tera-electro volts? Great. So until Christmas you can keep going with your normal beige lives, not taking any chances or risks, typing away in your hamster wheels. Two, remember that life can end at any moment, and get out of the wheel. To a beach. Preferably with another hamster. One with a nice butt and a pretty smile.

These are the computer images showing the first collisions:

Two circulating beams bring first collisions in the LHC

Geneva, 23 November 2009. Today the LHC circulated two beams simultaneously for the first time, allowing the operators to test the synchronisation of the beams and giving the experiments their first chance to look for proton-proton collisions. With just one bunch of particles circulating in each direction, the beams can be made to cross in up to two places in the ring. From early in the afternoon, the beams were made to cross at points 1 and 5, home to the ATLAS and CMS detectors, both of which were on the lookout for collisions. Later, beams crossed at points 2 and 8, ALICE and LHCb.

“It’s a great achievement to have come this far in so short a time,” said CERN* Director General Rolf Heuer. “But we need to keep a sense of perspective – there’s still much to do before we can start the LHC physics programme.”

Beams were first tuned to produce collisions in the ATLAS detector, which recorded its first candidate for collisions at 14:22 this afternoon. Later, the beams were optimised for CMS. In the evening, ALICE had the first optimisation, followed by LHCb.

“This is great news, the start of a fantastic era of physics and hopefully discoveries after 20 years’ work by the international community to build a machine and detectors of unprecedented complexity and performance,” said ATLAS spokesperson Fabiola Gianotti.

“The events so far mark the start of the second half of this incredible voyage of discovery of the secrets of nature,” said CMS spokesperson Tejinder Virdee.

“It was standing room only in the ALICE control room and cheers erupted with the first collisions,” said ALICE spokesperson Jurgen Schukraft. “This is simply tremendous.”

“The tracks we’re seeing are beautiful,” said LHCb spokesperson Andrei Golutvin, “we’re all ready for serious data taking in a few days time.”

These developments come just three days after the LHC restart, demonstrating the excellent performance of the beam control system. Since the start-up, the operators have been circulating beams around the ring alternately in one direction and then the other at the injection energy of 450 GeV. The beam lifetime has gradually been increased to 10 hours, and today beams have been circulating simultaneously in both directions, still at the injection energy.

Next on the schedule is an intense commissioning phase aimed at increasing the beam intensity and accelerating the beams. All being well, by Christmas, the LHC should reach 1.2 TeV per beam, and have provided good quantities of collision data for the experiments’ calibrations.

Whatever, I’m just happy we are not being sucked by a Black Hole right now. Life is good, my dear boys and girls. Life is good.

The LHC is a far better understood machine than it was a year ago. We’ve learned from our experience, and engineered the technology that allows us to move on. That’s how progress is made.

Wait wait wait. WAIT, Mr Director for Accelerators Steve Myers, Sir. What do you mean that the machine is “far better understood” now? How could they spend a billion bazillion dollars on this thing and not understand it in the first place? Do we really know what are we up to here? Should I book a ticket to Costa Rica and go watch the end of the world from the beach?

The LHC is now circulating beams for the first time since September 2008 when it suffered a serious malfunction. It has taken them a year to repair it, which will explain the origin of the Universe or kick all of our atomic arses out of it.

The LHC is back

Geneva, 20 November 2009. Particle beams are once again circulating in the world’s most powerful particle accelerator, CERN*’s Large Hadron Collider (LHC). This news comes after the machine was handed over for operation on Wednesday morning. A clockwise circulating beam was established at ten o’clock this evening. This is an important milestone on the road towards first physics at the LHC, expected in 2010.

“It’s great to see beam circulating in the LHC again,” said CERN Director General Rolf Heuer. “We’ve still got some way to go before physics can begin, but with this milestone we’re well on the way.”

The LHC circulated its first beams on 10 September 2008, but suffered a serious malfunction nine days later. A failure in an electrical connection led to serious damage, and CERN has spent over a year repairing and consolidating the machine to ensure that such an incident cannot happen again.

“The LHC is a far better understood machine than it was a year ago,” said CERN’s Director for Accelerators, Steve Myers. “We’ve learned from our experience, and engineered the technology that allows us to move on. That’s how progress is made.”

Recommissioning the LHC began in the summer, and successive milestones have regularly been passed since then. The LHC reached its operating temperature of 1.9 Kelvin, or about -271 Celsius, on 8 October. Particles were injected on 23 October, but not circulated. A beam was steered through three octants of the machine on 7 November, and circulating beams have now been re-established. The next important milestone will be low-energy collisions, expected in about a week from now. These will give the experimental collaborations their first collision data, enabling important calibration work to be carried out. This is significant, since up to now, all the data they have recorded comes from cosmic rays. Ramping the beams to high energy will follow in preparation for collisions at 7 TeV (3.5 TeV per beam) next year.

Particle physics is a global endeavour, and CERN has received support from around the world in getting the LHC up and running again.

“It’s been a herculean effort to get to where we are today,” said Myers. “I’d like to thank all those who have taken part, from CERN and from our partner institutions around the world.”

The book’s called Voyage To The Heart Of Matter – The Atlas Experiment At CERN and it’s written by Emma Sanders and crafted by Anton Radevsky. It’ll be out at the end of November and run for about $US33. I just want one because it’ll satisfy both the physics dork and the bookworm inside me all at once. [Atlas via Shiny Shiny via OhGizmo!]

Separate from the LHC itself, CERN’s labs are sprawling and fairly old, so it’s understandable if they’re a little industrio-creepy. Which they are!

But considering the facilities are intended for similar purposes (in theory), and the CERN already employs a real-life Gordon Freeman, the likeness here is just uncanny, as if CERN ripped the models and textures from Valve’s FPS and somehow actualised them. (Or, you know, the other way around, which actually makes sense.) Check out the full gallery at: [CERNLove via Reddit]

The results of that first test—a run of particle beams through the 27km tunnel—showed the machine in perfect working order. The scientists are hoping to have the LHC up and running as good as new in November, which after careful research I conclude is less than a week away. Sorry to drop the end of the world on you like that, but you’re all going to die in November. Them’s the breaks! [Pop Sci]

Except, obviously, in the case of the LHC this is real hyperdrive technology and testing we’re talking about, whereas, sadly, Han’s bucket of bolts will remain firmly in the realm of sci-fi.

But no matter. If physicist Franklin Felber gets his way then an ancient, unknown German research paper from the 1920s could get dusted off and have its thesis tested in the LHC. Called the “Foundations of Physics,” the paper proposed that under certain circumstances a stationary mass can, on occasion, repel a “relativistic particle.” Ferber’s theory proposes that the opposite must also be true, and that this can be tested at the LHC.

In the experiment, Felber would monitor a test mass inside the ring as particles shoot past it. The work would not interfere with other already scheduled projects, and if it works we’d be one small step closer to unlocking that coveted near light speed achievement. That is, if the LHC ever starts up again. Where’s R2? [Technology Review via Engadget]

Click for artistic impression of terrorist at CERN.

According to French newspaper Le Figaro, judicial sources point that the man—who has been working as a particle physics contractor since 2003—has links to Al Qaeda groups in the Islamic Maghreb. Le Figaro said that he had suggested terrorist targets in French soil. There’s word if the target list also included the LHC, however.

In a public statement, CERN was quick to remember that the LHC is peaceful, and no gain can be obtained from it by any terrorist:

None of our research has potential for military application, and all our results are published openly in the public domain.

Indeed. Let CERN work alone in peace and fix the LHC while the rest of us don’t do our homework.

One message to all those trying to hurt others in the world, like Osama and Co.: Go f—k yourself. [Daily Mail]

A bunch of students at a Brisbane high school filmed a dirty porno in a high school bathroom the last time news of the Large Hadron Collider was hot. Yeah, that video was literally dirty. Remember high school bathrooms?

Basically the guy convinced his sweet, innocent and oh-so-stupid girlfriend that it was her last chance to lose her virginity as his buddy played hidden camera man, producer and distributor. The camera phone recorded underage sex act made its way through the community and could potentially result in child pornography production charges, although news.com.au claims it unlikely due to the age of all the participants.

No word on whether the sweet talker managed to hang on to the girl by convincing her that a miracle spared the world until November. [news.com.au]

The reasons floated for the collider’s foibles are many as of late, from faulty hoses to un-magnetic magnets to the aforementioned libidinous couple who’ve been assaulting coworkers’ ear drums with wanton abandon.

Nevertheless, pressure from scientists have forced CERN to start the LHC up in November, where it will then smash atoms at half power until next year—when it will have to be shut down again.

Meanwhile, this may all be moot, at least for now, as many scientists (publicly and privately) have turned their eager eyes to other colliders around the world, like Fermilab’s Tevatron, for use with similar experiments. [MSNBC]
