bascule Posted April 8, 2007 Share Posted April 8, 2007 http://www.timesonline.co.uk/tol/news/uk/article1626728.ece “There was a hell of a bang, the tunnel housing the machine filled with helium and dust and we had to call in the fire brigade to evacuate the place,” he said. “The people working on the test were frightened to death but they were all in a safe place so no-one was hurt.” An investigation by Cern researchers found “fundamental” flaws that caused the explosion, close to the CMS detector, one of the LHC’s most important experiments.

Pangloss Posted April 8, 2007 Share Posted April 8, 2007 The last bit of the article with the political angle was interesting, regarding the search for the Higgs boson. Kinda hard to imagine Fermilab would do something like that on purpose, considering what this may cost them in the long run, but I'm sure there will be speculation to that effect around the community.

Sayonara Posted April 8, 2007 Share Posted April 8, 2007 Oooh, that's a bit embarrassing. I wonder if Fermilab will be made to pay compensation? Link to comment Share on other sites More sharing options...
insane_alien Posted April 8, 2007 Share Posted April 8, 2007 i know they were hoping to create mini big bangs but thats just ridiculous Link to comment Share on other sites More sharing options...
bascule Posted April 8, 2007 Author Share Posted April 8, 2007 Looks like this bit is what went boom: Yikes! Link to comment Share on other sites More sharing options...
insane_alien Posted April 8, 2007 Share Posted April 8, 2007 the article said it was one of the magnets on the accelerator tunnel not the detector. although, both are pretty big and could blow up if you made them wrong. Link to comment Share on other sites More sharing options...
Severian Posted April 9, 2007 Share Posted April 9, 2007 To be honest, I think CMS will be rather happy this happened. They are quite a bit behind schedule and this will give them a chance to catch up. CMS's delay may not delay the switch on now. Also, since the explosion was in the tunnel, the work to repair it is decoupled from the work assembling the experiments (the things in the pic bascule showed - that is CMS I think). So it shouldn't delay the switch on much. And Fermilab really need a long time to build luminosity for a Higgs discovery (unless they are very very lucky) so I don't think a few months will give them it. For the official explanation of what happened see: http://user.web.cern.ch/user/QuickLinks/Announcements/2007/LHCInnerTriplet_1.html (Its a bit technical though) Link to comment Share on other sites More sharing options...
GutZ Posted April 14, 2007 Share Posted April 14, 2007 Review of engineering design documentation reveals that the longitudinal force generated by asymmetric loading was not included in the engineering design or identified as an issue in the four design reviews that were carried out. lmao opps. How long have they been in operation for (not full, but test capable)? Link to comment Share on other sites More sharing options...
YT2095 Posted April 15, 2007 Share Posted April 15, 2007 heh, that`s not at All like I excepted a Black Hole to look:rolleyes: Link to comment Share on other sites More sharing options...
Severian Posted April 23, 2007 Share Posted April 23, 2007 lmao opps. How long have they been in operation for (not full, but test capable)? They had just put them in. This was the first test I think. Link to comment Share on other sites More sharing options...
