The results from the highest-energy particle experiments carried out at the Large Hadron Collider (LHC) in December have begun to yield their secrets.

Scientists from the LHC’s Compact Muon Solenoid detector has now totted up all of the resulting particle interactions.

They wrote in the Journal of High Energy Physics that the run created more particles than theory predicted.

However, the glut of particles should not affect results as the experiment runs to even higher energies this year.

The LHC is designed to smash together particles and atoms circling its 27km-tunnel in a bid to find evidence of further particles that underpin the field of physics as it is currently formulated.

The December announcement of particle beam energies in excess of one trillion electron volts made the LHC the world’s highest-energy particle accelerator.

Hey, now, this is some great news, right? The trouble-plagued Large Hadron Collider looks to be doing a bang up job in some of its primary tasks. After breaking the energy record previously held by the Tevatron particle accelerator back at the end of November, 2009, reports are now coming in that the LHC is, in fact, producing some extremely high energy collisions. A research team led by MIT, CERN and the KFKI Research Institute for Particle and Nuclear Physics in Budapest, Hungary have released a report detailing findings that the collisions are producing an “unexpectedly” high number of particles called mesons, subatomic particles composed of one quark and one antiquark. The research is considered one of the first steps in the search for rarer particles, and the elusive, theoretical Higgs Boson. The paper, published in the Journal of High Energy Physics has led scientists to fine-tuning their predictive models for how many mesons will be found in even higher energy collisions.

“Yesterday evening the Large Hadron Collider at CERN for the first time accelerated protons in both directions of the ring to 1.18 TeV. Even though the 1 TeV barrier per beam was first broken a week ago, this marks the first time that the beam was in the machine in both directions at the same time allowing possibly for collisions at a center of mass energy of 2.36 TeV. Although the test lasted mere minutes, it was enough to have detectors record the very first events at 2.36 TeV. LHC passes Tevatron (the particle collider at Fermilab that operates at 1.96 TeV) and becomes the highest energy particle collider in the world (so far it was effectively just the highest energy storage ring…)”

CERN announced early Monday that the Large Hadron Collider has become the world’s highest-energy particle accelerator. The LHC pushed protons to 1.18 TeV (trillion electron volts), surpassing the previous record of 0.98 TeV held by Fermilab’s Tevatron.

The LHC had a rough start: It suffered a mechanical failure just a week after it fired up for the first time in September 2008. Now, 10 days after it turned on again, scientists are celebrating with their fingers crossed that the machine is safely on its way to the physics experiments they plan to begin next year when the LHC has reached its target energy of 7 TeV.

“Physicists are getting excited about the possibility of micro-black holes (MBH) being produced by the LHC and an international group of researchers have done the math to see what kind of impact they could have on the Earth. Unfortunately, if you’re a megalomaniac looking for your next globe-eating weapon, you can scrub MBHs off your WMD list. If a speedy MBH is produced, flying through our planet, it will only have a few seconds to accrete the mass of a few atoms. It would then be lost to space where it will evaporate. If a slow MBH is produced, dropping into the Earth where it sits for a few billion years, the results are even more boring.”

The Large Hadron Collider, smasher of particles, will get another chance to prove itself this November. The restart will begin with tests at half power, a mere 7 trillion electron volts (TeV), and ramp up slowly to the designed goal of 14 TeV. “Measurements indicate that some of the electrical connections could not safely handle the amount of current needed to run at the full 14 TeV, so will need to be replaced before dialing up the energy that far. But even 7 TeV is much higher than physicists have ever probed in the laboratory before. The Tevatron accelerator at Fermilab in Batavia, Illinois, is the current record holder, with collisions at 2 TeV.”

Like many other people, I was following the events surrounding the switching-on of the Large Hadron Collider (LHC) at CERN yesterday with great interest. The BBC has had some quite good coverage, particularly The Big Bang Machine, however I felt a bit frustrated with some of the explanations. On all of the coverage of the LHC we learned that:

* It is 27 km in circumference
* It is cooled close to absolute zero (about -271°C)
* Twin proton beams will be accelerated to speeds very near to the speed of light
* The protons will then be collided, resulting in them being “smashed apart”
* This will recreate conditions as they were very shortly after the start of the Big Bang
* Detectors will record incredibly short-lived products of the collisions, looking (among other things) for the theoretically postulated but never observed Higgs boson.

Remember, no smashing will be done today, for that we’ll have to wait until later this month. We’ll update you here as things progress.

09:49 — Confirmed, the first beam of protons has been fired! It took 48-seconds for the pulse to generate and then a tiny flash of light on a computer screen indicated a successful firing around the first 3-km of the 27-km ring — they will methodically extend the range throughout the day.

10:25 — The beam just completed the full ring (in stages) in less than an hour. Things are going much more quickly than expected. Counterclockwise test next.

12:18 — CERN estimates that the LHC will be fully operational for physics work in the next few months. Added NASA-like video of the reaction to the full-loop, first beam success after the break (watch for two flashes on the left-most screen).
