 Official information still very limited  Last press release (Sept. 23) refers to “large helium leak”  No pictures.  Logbook entries noticeably terse. 9/7/2015 Eric Prebys - All Experimenters' Meeting

 Italian newspapers are very poetic (at least as translated by “Babel Fish”): "the black cloud of the bitterness still has not been dissolved on the small forest in which they are dipped the candid buildings of the CERN" “Lyn Evans, head of the plan, support that it was better to wait for before igniting the machine and making the verifications of the parts.“*  Or you can Google “What really happened at CERN”: 9/7/2015 Eric Prebys - All Experimenters' Meeting * “Big Bang, il test bloccato fino all primavera 2009”, Corriere dela Sera, Sept. 24, 2008 ** **

 Tunnel secure, and safety systems up and running  Crew went in today for first inspection of interconnect at “ground zero”.  No details yet  Level of visible damage not clear  Still no pictures released, but those that have seen them describe them as “dramatic”.  Estimates are that “on the order of a dozen” magnets will need to be replaced:  Unconfirmed Lyn Evans quote: “8 dipoles and 4 quadrupoles”.  Big questions:  Why didn’t quench protection system work?  What went wrong with the pressure relief system?  Is there a simple fix to make it work in the future?  Assuming the answer to the third question is yes, the current schedule for beam is May 1 or June 1, 2009  If the answer is no, it’s too early to come up with a schedule. 9/7/2015 Eric Prebys - All Experimenters' Meeting
