8.38AM CET — Hello! It wouldn’t be the LHC without something going wonky and sure enough, we’re told a power converter went down while things were ramping up this morning. Not to worry though, apparently these things happen often, and will be overcome without much fuss. First collisions are expected in about two hours.
8.56AM — They’ve lost a beam. Cryogenics problems have caused one of the beams to go astray, meaning that the ramping process will have to be restarted. It’s been four minutes now and they’ve yet to determine what the particular cause was or where that beam went. People near the Franco-Swiss border should probably remain indoors this morning.
9.40AM — Time until the collisions is being filled with tours of the experiment control rooms. Lots of trendy people in there, wearing checked shirts, scruffy jumpers and denim jackets — and hey, a dude named Wolfram! This is like a bad Bond movie.
10.09AM — Earlier issue has been identified as an “electrical perturbation” that took out a couple of sectors of the LHC. The magnets in the relevant areas are presently being reset, which should take about an hour, to be followed by a new beam being injected and then ramping starting anew. Judging by all the interviews they’re doing, we suspect they might be stretching this thing out just to give all of their physicists some screen time.
11.47AM — Wake up, they’re back! The beams are now in position and are about to begin acceleration within minutes. Former project leader Lyn Evans was brought out for a quick interview and given just enough time to express that he’s “very confident” things will go right this time.
12.02PM — We’ve just passed 1 TeV of energy per beam and are slowly but surely ramping up to the full 3.5. Full energy is expected at 12.30PM CET, so if you have anything you want to do before the end of the world, now might be the time to do it. You know, just in case.
12.37PM — 3.5 TeV reached on each beam, and we’re still here. Everything is in place, now all that remains is the tiny matter of smashing the protons into another one.
12.59PM — The beams are being brought closer and closer together. And yes, they’re now aligned! The LHC is in collision mode, we’re almost there.
1.01PM — They need to establish stable beams before delivering the protonic crashes. We still think they’re teasing it out for dramatic effect.
1.05PM — Finally! First collisions at 7 TeV are now happening at a rate of 40 events per second.
1.24PM — Nothing exciting left for us here. Just a bunch of scientists tidying up particle trajectories and collating tons of data. We’ll leave them to it, and we’ll leave you with a video of the big excitement.
Update: The momentous first protonic collisions at 7 TeV have just taken place, at just past 1PM CET. Now the time comes for researchers to parse all the incoming raw data, pore over it, analyze it, etc. We’ll leave that to them, it’s not like you can expect the God Particle to be discovered instantly. To fill the time, we invite you to come past the break for our blow-by-blow updating adventure from this morning plus video of the big moment.
CERN Press release:
Geneva, 30 March 2010. Beams collided at 7 TeV in the LHC at 13:06 CEST, marking the start of the LHC research programme. Particle physicists around the world are looking forward to a potentially rich harvest of new physics as the LHC begins its first long run at an energy three and a half times higher than previously achieved at a particle accelerator.
“It’s a great day to be a particle physicist,” said CERN1 Director General Rolf Heuer. “A lot of people have waited a long time for this moment, but their patience and dedication is starting to pay dividends.”
“With these record-shattering collision energies, the LHC experiments are propelled into a vast region to explore, and the hunt begins for dark matter, new forces, new dimensions and the Higgs boson,” said ATLAS collaboration spokesperson, Fabiola Gianotti. “The fact that the experiments have published papers already on the basis of last year’s data bodes very well for this first physics run.”
“We’ve all been impressed with the way the LHC has performed so far,” said Guido Tonelli, spokesperson of the CMS experiment, “and it’s particularly gratifying to see how well our particle detectors are working while our physics teams worldwide are already analysing data. We’ll address soon some of the major puzzles of modern physics like the origin of mass, the grand unification of forces and the presence of abundant dark matter in the universe. I expect very exciting times in front of us.”
“This is the moment we have been waiting and preparing for”, said ALICE spokesperson Jürgen Schukraft. “We’re very much looking forward to the results from proton collisions, and later this year from lead-ion collisions, to give us new insights into the nature of the strong interaction and the evolution of matter in the early Universe.”
“LHCb is ready for physics,” said the experiment’s spokesperson Andrei Golutvin, “we have a great research programme ahead of us exploring the nature of matter-antimatter asymmetry more profoundly than has ever been done before.”
CERN will run the LHC for 18-24 months with the objective of delivering enough data to the experiments to make significant advances across a wide range of physics channels. As soon as they have “re-discovered” the known Standard Model particles, a necessary precursor to looking for new physics, the LHC experiments will start the systematic search for the Higgs boson. With the amount of data expected, called one inverse femtobarn by physicists, the combined analysis of ATLAS and CMS will be able to explore a wide mass range, and there’s even a chance of discovery if the Higgs has a mass near 160 GeV. If it’s much lighter or very heavy, it will be harder to find in this first LHC run.
For supersymmetry, ATLAS and CMS will each have enough data to double today’s sensitivity to certain new discoveries. Experiments today are sensitive to some supersymmetric particles with masses up to 400 GeV. An inverse femtobarn at the LHC pushes the discovery range up to 800 GeV.
“The LHC has a real chance over the next two years of discovering supersymmetric particles,” explained Heuer, “and possibly giving insights into the composition of about a quarter of the Universe.”
Even at the more exotic end of the LHC’s potential discovery spectrum, this LHC run will extend the current reach by a factor of two. LHC experiments will be sensitive to new massive particles indicating the presence of extra dimensions up to masses of 2 TeV, where today’s reach is around 1 TeV.
“Over 2000 graduate students are eagerly awaiting data from the LHC experiments,” said Heuer. “They’re a privileged bunch, set to produce the first theses at the new high-energy frontier.”
Following this run, the LHC will shutdown for routine maintenance, and to complete the repairs and consolidation work needed to reach the LHC’s design energy of 14 TeV following the incident of 19 September 2008. Traditionally, CERN has operated its accelerators on an annual cycle, running for seven to eight months with a four to five month shutdown each year. Being a cryogenic machine operating at very low temperature, the LHC takes about a month to bring up to room temperature and another month to cool down. A four-month shutdown as part of an annual cycle no longer makes sense for such a machine, so CERN has decided to move to a longer cycle with longer periods of operation accompanied by longer shutdown periods when needed.
“Two years of continuous running is a tall order both for the LHC operators and the experiments, but it will be well worth the effort,” said Heuer. “By starting with a long run and concentrating preparations for 14 TeV collisions into a single shutdown, we’re increasing the overall running time over the next three years, making up for lost time and giving the experiments the chance to make their mark.”
“The study – which is based on the concept that physics can be used to characterize the evolution of civilization – indicates:
- Energy conservation or efficiency doesn’t really save energy, but instead spurs economic growth and accelerated energy consumption.
- Throughout history, a simple physical “constant” – an unchanging mathematical value – links global energy use to the world’s accumulated economic productivity, adjusted for inflation. So it isn’t necessary to consider population growth and standard of living in predicting society’s future energy consumption and resulting carbon dioxide emissions.
- “Stabilization of carbon dioxide emissions at current rates will require approximately 300 gigawatts of new non-carbon-dioxide-emitting power production capacity annually – approximately one new nuclear power plant (or equivalent) per day,” Garrett says. “Physically, there are no other options without killing the economy.”
Garrett says his study’s key finding “is that accumulated economic production over the course of history has been tied to the rate of energy consumption at a global level through a constant factor.”
That “constant” is 9.7 (plus or minus 0.3) milliwatts per inflation-adjusted 1990 dollar. So if you look at economic and energy production at any specific time in history, “each inflation-adjusted 1990 dollar would be supported by 9.7 milliwatts of primary energy consumption,” Garrett says.
“Viewed from this perspective, civilization evolves in a spontaneous feedback loop maintained only by energy consumption and incorporation of environmental matter,” Garrett says. It is like a child that “grows by consuming food, and when the child grows, it is able to consume more food, which enables it to grow more.”
He says the idea that resource conservation accelerates resource consumption – known as Jevons paradox – was proposed in the 1865 book “The Coal Question” by William Stanley Jevons, who noted that coal prices fell and coal consumption soared after improvements in steam engine efficiency.
Garrett says often-discussed strategies for slowing carbon dioxide emissions and global warming include mention increased energy efficiency, reduced population growth and a switch to power sources that don’t emit carbon dioxide, including nuclear, wind and solar energy and underground storage of carbon dioxide from fossil fuel burning. Another strategy is rarely mentioned: a decreased standard of living, which would occur if energy supplies ran short and the economy collapsed, he adds.
“Fundamentally, I believe the system is deterministic,” says Garrett. “Changes in population and standard of living are only a function of the current energy efficiency. That leaves only switching to a non-carbon-dioxide-emitting power source as an available option.”
full article from this mash-up
interesting that by taking a physics perspective, he steps outside the bounds of the normal view of climate change and its relation to the economy. we are always assuming that certain parts of our equations are true, leaving no room for fundamentally shaking our ideation of change and limiting what we have to work with. instead of reworking things form ground up, we always get stuck tweaking.
its the economy stupid. through and through. but what does that really mean…?
Nassim Haramein is now blogging….Thank Tetragrammaton
You can also become friends with him on Facebook
He actually updates multiple times a day
It’s fuckin tight
If you like these things Graham Hancock has a nice newsfeed here as well.

homad, deadindenver, Nassim Haramein and The Alien Ark Capacitor « The Teleomorph, and 2 others are discussing. Toggle Comments
After billions of Euros and decades of preparation, the worlds largest particle accelerator was booted up yesterday. The initial low energy tests ran successfully and encouraged the scientists to look forward to the massive collisions that will be underway in the coming months in an attempt to find the Higgs-Sposon (god particle), lauch inquiries into the nature of anti and dark matter and attempt to reach or exceed the Planck time as defined by Quantum Mechanics as the farthest back we can look into the past. Particles will be collided into one another traveling at 99.99% of the speed of light creating enough energy to coalesce into physical matter for a fraction of a second. The hope is that these transitory particles will shed new light into the nature of the universe. While the endeavor is certainly another in the line of masculine, explosive attempts to understand our condition, it is exciting none the less to see the world come together in an attempt to figure this mess we call the universe out. It may be misguided and a bit dangerous but I think that we could gain some cool new insight which could effectively rip open the rather (experimentally) dormant realm of theoretical physics in the near future. Hopefully it brings a new golden age of progress and enlightenment instead of the destruction and terror that some foresee. Oh and by the way, the internet was invented at CERN for the analyzation of particle physics experiments and The Grid (internet 2.0) was spawned to make calculations for the new collider more streamlined and accessible worldwide. Cool.
