The Large Hadron Collider is built to speed the subatomic particles called protons to nearly the speed of light and then smash them together in search of new forms of matter and energy that cannot be produced in smaller machines. Two weeks ago, the center for nuclear research, which is outside Geneva, sent the first beams of protons around the machine’s 17-mile-long underground racetrack. But last Friday the machine was shut down after an electrical connection between two of the superconducting electromagnets that steer the protons suffered a so-called quench, heating up, melting and leaking helium into the collider tunnel. Liquid helium is used to cool the magnets to superconducting temperatures of only about 3.5 degrees Fahrenheit above absolute zero. Stray heat can cause the magnets to lose their superconductivity with potentially disastrous consequences. To make repairs, it will be necessary to warm the magnets up and then cool them back down again, which takes at least two months, engineers say. And that leaves scant time to run the collider before it has to shut down for the winter in early December to save money on electricity. Engineers at the European Center for Nuclear Research have already scheduled a series of tests and other activities intended to bring the collider up to its full potential of delivering protons with energies of 7 trillion electron volts to their deaths in primordial fireballs.
In a statement released by the center’s press office, Robert Aymar, the director-general of the laboratory, acknowledged that the delay “is undoubtedly a psychological blow,” but that the success of putting the first beam through the $8 billion machine was testimony to the skill and dedication of the center’s team. “I have no doubt that we will overcome this setback with the same degree of rigor and application,” he said.
It's time to find something else to blame for all the recent strange occurrences in your life: The Large Hadron Collider, which had become a favorite culprit for everything from lost keys to lost jobs, will remain shut down until spring.
