Primed: The smashing science behind particle accelerators
Primed goes in-depth on the technobabble you hear on Engadget every day -- we dig deep into each topic's history and how it benefits our lives. You can follow the series here. Looking to suggest a piece of technology for us to break down? Drop us a line at primed *at* engadget *dawt* com. Long before the Large Hadron Collider (LHC) could smash its first atoms, researchers manning the Tevatron collider at Fermilab, in a quiet suburb 40 miles west of Chicago, raced to find evidence that the Higgs boson exists. After roughly three decades of service, the Tevatron shut down for good in late 2011, dealing the city of Batavia's largest employer a significant blow. Less than 18 months later, the LHC (the Tevatron's technological successor) also went offline - albeit temporarily. Only four years after recording its first proton collisions, the team at CERN is already scrambling to upgrade the staggering LHC, which lies under parts of no less than five cities in both France and Switzerland. With the world's largest particle colliders smashing a whole lot of nothing together for the next two years at least, the field of high-energy physics research is starting to look resource-starved. Of course, many might ask why exactly we need giant atom smashers like this, or even how they work. It turns out that first part is quite a bit easier to answer than the second. During the last several decades, particle accelerators have revealed the existence of elementary particles such as quarks, led to the discovery of antimatter and generally helped us unlock the mysteries of the universe. And once they were done splitting atoms and probing the darkest corners of theoretical physics, accelerators often led to breakthroughs in medical imaging and cancer research. So, as massive colliders seem ready to land on the endangered species list, it seems as good a time as any to explain what a particle collider is, how it works and what we as a society have to gain from the research.
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.
