Anyone who has struggled to change a fuse in their home should pity the scientists at the CERN laboratory in Geneva. Last Friday, just nine days after celebrating the successful test run of the largest particle accelerator ever constructed, a tiny electrical connection between two magnets overheated and caused a minor meltdown...
...however, repair work can't begin because the machine is still too cold; it will take about a month to warm up the area to a temperature at which replacement parts can be inserted. It will take another month to cool it back down, and given that CERN has pledged not to run its giant machine - which requires as much power as the entire city of Geneva - during winter months when Europe's energy needs are highest, Friday's breakdown could delay the actual smashing of atoms until early next year...
...CERN spokesman James Gillies called the fault a "teething problem" and said that previous accelerators that used superconductivity - i.e., low temperatures that allow metals to conduct electricity without resistance - also faced early problems before "running pretty smoothly after they were sorted out." Even so, "it's certainly a disappointment," he added...
...which cosmologists and theoretical physicists can extrapolate. But they have less exalted reasons to hope for the LHC's success: After a glut of funding for particle physics in the '80s promised the building of several particle accelerators of equivalent power to the LHC, recent funding cuts mean the CERN experiment is now the only game in town. If it fails to provide results, physicists worry they will have to struggle to justify new, even more powerful machines, not to mention the salaries of thousands of scientists needed to build and operate them. Already, the LHC has been delayed several...
Gillies says that Friday's breakdown released a "large amount" of helium into the tunnel but that CERN's safety protocols ensured there was no risk to staff. Scientists are not allowed into the tunnel when the machine is running, he says, and first responders after the fault all wore respiratory equipment. All scientists working in the underground ring also carry portable respirators, which they are instructed to use within seconds of a helium leak...
