CERN Successfully Brings Large Hadron Collider Back Online


Hooray!:  courtesy CERN

Much beset by magnet quenches, birds, bread, black holes, evil time travelers, and fools, the Large Hadron Collider successfully came online and orbited a proton beam today!

Photographs of the triumphant moment are within.

Following Baguette Incident, Large Hadron Collider Set for Restart This Week

CERN scientists hope to finally get some particle smashing done, after more than a year of delays and repairs

A bird dropping a baguette temporarily shut down the $5 billion Large Hadron Collider earlier this month. But scientists have a good feeling about the restart, which is slated for Friday, the The Guardian reports.

Baguette Dropped From Bird's Beak Shuts Down The Large Hadron Collider (Really)

The Large Hadron Collider, the world's most powerful particle accelerator, just cannot catch a break. First, a coolant leak destroyed some of the magnets that guide the energy beam. Then LHC officials postponed the restart of the machine to add additional safety features.

How To Fix a Broken Collider: the LHC's Restart Checklist


Before scientists can put the Large Hadron Collider back to work this month solving the mysteries of particle physics, the LHC’s engineers face critical repairs to the $5-billion device. First up: Fix the 53 superconducting magnets trashed in September 2008 when a power cable broke, causing the magnets to warm above their –458˚F operating temperature and lose conductivity, or “quench.” Then pipes for helium coolant melted, further damaging the magnets.

LHC Reawakens, Sending Proton Beams Running at the Speed of Light


Over the weekend, Cern ran particle beams through the Large Hadron Collider for the first time since it was shut down last September. After a helium leak caused magnets to overheat, operations at the LHC were suspended for cleanup and repairs. After tests on October 23 and 25, scientists hope to have the LHC running again in full by November.

LHC Test Could Lead to Hyperdrive Space Propulsion (Well, In Theory)


Add one more thing to the list of mysteries, theories, and unsubstantiated ideas that will be confirmed/denied/debunked if CERN ever gets the Large Hadron Collider up and running: hyperdrive spacecraft propulsion.

In 1924, German mathematician David Hilbert published a paper noting a pretty amazing side effect to Einstein's relativity: a relativistic particle moving faster than about half the speed of light should be repelled by a stationary mass (or at least it would appear to be repelled, to an inertial observer watching from afar).

The Race to the Higgs Boson: LHC Versus Tevatron

It's on!

While the LHC's in the shop for repairs from its massive breakdown last September, an older particle accelerator might beat them to finding the Higgs boson, the fundamental particle thought to give matter mass.

At a conference last week, Tevatron physicists threw down the gauntlet, vowing that by 2011, the Tevatron accelerator (located at Fermi National Accelerator Lab outside Chicago) will be able to definitively prove or disprove the existence of the Higgs boson.

Dormant Supercollider Generates Star Power

Is there such a thing as excessively popular science?

The troubled Large Hadron Collider, switched on last fall and then off again when its magnets broke, has a bright future.

Tom Hanks, star of Big and The Polar Express, has been invited to turn on the system when its repairs are complete, in what may be history's first celebrity restarting of a particle accelerator.

Delay (Anew) for the LHC Restart

Waiting for the LHC online-again date with bated breath? May want to inhale again

All those planning for the end of the world in July, rest easy and enjoy the summer.
The European Organization for Nuclear Research (CERN) is delaying the Large Hadron Collider (LHC) startup another two months. According to CERN, the LHC will go live in September and collisions will begin in October.

Threat Watch, LHC?

A new report has people insisting the LHC's miniscule black holes might be more dangerous than previously believed

After decades of work, the Large Hadron Collider went live 143 days ago and went down 139 days ago. Its being offline, however, has hardly put an end to speculation over what exactly will happen when the repairs are completed and the switch is flipped on the world's largest particle accelerator. Scientists from the Universities of Bologna and Alabama recently submitted a paper to Cornelll's arXiv.org exploring the possibility that those (harmless) microscopic black holes we'd heard so much about could stick around longer than previously believed. No matter that their conclusion was basically, still: "so what? Ain't gonna do nothin." News outlets,as SciAm notes, jumped over the story and the anti-LHC kook-contingent resurfaced.

So here's to you, naysayers and doomsdayers alike. After the jump, a very special episode of "Science of YouTube," wherein the LHC goes online and the Earth is destroyed. Enjoy!
