Bad Math Causes Explosion at CERN Collider
javipas writes "The Large Hadron Collider at the CERN has suffered a big explosion deep inside that has caused a leak of hellium gas and the quick evacuation of everyone working there. The reason: a mathematical mistake that affected the design of the giant superconductive magnets made by Fermilab. Now the company will have to repair and upgrade the 24 magnets that are installed on the 27 km. circunference of one of the most important research centers on Earth." This story might seem strangely familiar to you.
Talk about missed opportunities. I just listened to an NPR story at around 8:20 eastern time (US) about particle physics and the super collider. They mentioned how a particle zooming around in it would have the force of a bus, and colliding two particles would be an enormous crash. They talked about how particle physics has stagnated for the past few decades, about how the collider was built, and oddly enough, about what a breach of the coil would do. But no mention of an "accident." Hmmm. I guess I need to mail my pledge check.
My user name was a mistake. Input wasn't restricted, my bad.
On a somewhat lighter note (since no one was hurt), an MR tech colleague of mine recounted the story (which I may be mangling a bit) of an intentional quench of an MRI at the facility where she worked previously. (I believe the magnet was either being decommissioned, or at least being moved to a different building -- regardless, they needed to release the helium).
Apparently, they put out an announcement that morning (and earlier in the week), notifying everyone at the facility that the quench would be occurring at some specified time, and not to be alarmed. One of the senior researchers had been away at a conference for a few days, and arrived just as the quench was occurring. As they opened the vents to the roof and released the liquid helium, the suddenly-expanding cold gas shot up in column for a bit, condensing moisture in the air around it, before expanding out, and forming a wider ball.
Needless to say, this researcher was quite shocked to get back to work in time to see a mushroom cloud over the building.
