Pour one out for the Tevatron particle accelerator, because it's shutting down today
The eyes of the physics community are collectively fixed upon Illinois today, where, later this afternoon, researchers at Fermilab will shut down the Tevatron particle accelerator... for good. That's right -- the world's second-largest collider is being laid to rest, after a remarkable 25-year run that was recently halted due to budgetary constraints. Earlier this year, Fermilab's scientists and a group of prominent physicists pleaded with the government to keep the Tevatron running until 2014, but the Energy Department ultimately determined that the lab's $100 million price tag was too steep, effectively driving a nail through the accelerator's subterranean, four-mile-long coffin. First activated in 1985, the Tevatron scored a series of subatomic breakthroughs over the course of its lifespan, including, most notably, the discovery of the so-called top quark in 1995. Its groundbreaking technology, meanwhile, helped pave the way for CERN's Large Hadron Collider, which will now pursue the one jewel missing from the Tevatron's resume -- the Higgs boson. Many experts contend that the collider could've gone on to achieve much more, but its ride will nonetheless come to an inglorious end at 2PM today, when Fermilab director Pier Oddone oversees the Tevatron's last rites. "That will be it," physicist Gregorio Bernardi told the Washington Post. "Then we'll have a big party."
Large Hadron Collider smashes beam intensity record, inches closer to discovering God particle
Already a record holder for mashing protons together at 7 TeV (trillion electron volts), the Large Hadron Collider can now add world's brightest beam to its list of accomplishments. Beam intensity is a way of measuring the number of collisions in its 17-mile-long track, and a higher intensity means more impacts -- which, in turn, means more data, increasing the likelihood that the elusive Higgs boson will rear its head (should such a thing exist). The LHC smashed the previous luminosity record set last year by the Tevatron collider. What's next for the CERN team, with two world records under its belt? Largest beard of bees.
