I have in the past had bad experiences with synchrotons. They really don't like my presence. (Nor apparently do reactors, but at least 'we' still managed to get data out of the ILL.) YAY!!

I promise to stay away from Geneva. I have in the past had bad experiences with synchrotons. They really don’t like my presence. (Nor apparently do reactors, but at least ‘we’ still managed to get data out of the ILL.)

But seriously, I'm very happy to hear the news. Really, really looking forward to the results! Don’t cross the beams!

Evidently the decision was made to start the beam commissioning next month even though the magnets will only have been commissioned to 2kA, not the 6kA needed for 3.5 TeV/beam. The higher energy will have to wait forJanuary. I don't think CERN has publicly announced this, but the news somehow did make it to the NYT blog... http://topics.blogs.nytimes.com/2009/10/27/the-cosmic-countdown-in-geneva-goes-on/ The latest schedule I’ve seen has collisions only a 1.1 TeV/beam by the end of the year.
