The Large Hadron Collider is smashing protons together again
It's been a long wait, but finally CERN's Large Hadron Collider (LHC) is back doing what it does best: smashing protons together. The machine was effectively shut down for two years while engineers in Switzerland carried out important upgrades. Scientists started firing proton beams again back in April, but avoided any collisions while they checked the new components were working properly. Now, CERN has announced that it's carrying out proton-proton collisions again. The beams are being fired at a lower energy of 450 gigaelectronvolts (GeV), however, so that CERN can check its particle detection systems are firing correctly. The plan is to ramp up the LHC so it can handle dual proton beams at 6.5 TeV - almost double what it was operating at before the shutdown -- for 13 TeV collisions later this summer. The Higgs boson was discovered last time, so we're hoping something equally remarkable is uncovered during its sophomore season.
Large Hadron Collider affected by full moon, ocean commiserates
Large Hadron Collider not running properly? If you've read the docs and restarted it, check for a full moon. After noticing fewer particle collisions while on her shift, Pauline Gagnon reached out to a control room operator who casually explained that they adjust beam alignment during full moons. Yes, the tide-producing orbit of Earth's satellite tugs the LHC's inner workings ever so slightly askew. Though minute, the changes add up over the collider's 27km circumference and are picked up by monitoring equipment sensitive enough to measure elementary particles. However, Luna isn't the only thing that affects the accelerator -- the water level in Lake Geneva and passing high-speed rail trains also do the trick. Will your hand react differently to the LHC's beam under a Harvest Moon? Probably not. In any case, hit the source for the scientific details.
Large Hadron Collider to run at half-power until end of 2010
After a series of setbacks, delays, and potential world-ending mishaps, it seems that the scientists at CERN have decided to take it easy with the Large Hadron Collider, and have announced that they plan to operate it at an energy of 3.5 TeV (or trillion electron volts) per beam when they start it up again in November of this year. If that goes well, they'll then cautiously ramp things up to 5 TeV per beam, before starting to shoot for a full 7 TeV per beam by the end of 2010. So, mark your calendars... while you still can.
Large Hadron Collider restart, end of the world pushed back to mid-November
Still undecided about what to do with those precious few months before the biggest doomsday since Y2K? Then you're in luck, 'cause the much anticipated / feared restart of the Large Hadron Collider has now been delayed yet again, almost exactly a month after the last delay. This time it looks like a couple of vacuum leaks are the culprit, and CERN says that the collider is now unlikely to restart before mid-November, which just so happens to coincide with the peak of the Leonids meteor shower. Coincidence? Yes, yes it is.
Large Hadron restart delayed again -- you can relax until October
If you were enjoying these warmer months, taking time away from terrestrial black hole spotting due to the continued deactivation of CERN's Large Hadron Collider, feel free to extend those summer vacation plans a little bit. The particle crasher and supposed non-threat to life as we know it was previously set to restart in September after some damage put it on the inactive list many moons ago. Now CERN's Head of Communications, James Gillies, is saying that the restart is likely to be smashed back a few more weeks into October, meaning New Englanders might just get in one more leaf peeping season before all we know is mashed into an incomprehensibly small ball of matter from which nothing can escape -- not even Gundam robots.
