In the last posting<\/a> I linked to the web-site for next week’s LHC Performance workshop at Chamonix, where the state of efforts to recover from last September’s accident and plans for this year will be discussed. As in many previous cases, linking to an authoritative information source about what is going on at the LHC had the effect of it being quickly shut off to the public. I guess CERN really is serious about the idea that information about problems at the LHC is now only supposed to come from the DG’s office.<\/p>\n

So, from now on, I’m sorry to have to do this, but I won’t be linking to any such information sources that people point me to or that I run across. Instead, I’ll try to continue to post here authoritative information that comes my way, without indicating its source. Today, I’ll just note that I’ve heard from an authoritative source about the current informed guesses for when the LHC will be able to start doing physics. The current hope is for first usable collisions at 5 TeV (per beam) in October, with two months for a physics run at that energy before winter shutdown. Peak luminosity would be a few times 1031<\/sup>, integrated luminosity a few tens of pb-1<\/sup>.<\/p>\n

Update<\/strong>: CERN does seem to be making an effort to put out more information about the status of the LHC through their press office. Yesterday there was this update<\/a> posted as “breaking news”, not waiting for the next issue of the weekly bulletin. The news in the update is uniformly good, telling us about how it has been “a good week”. What will be interesting to see in the future is whether less encouraging news makes it out to the public…<\/p>\n

Update<\/strong>: The web-page denying access to the Chamonix slides has been changed, it now reads:<\/p>\n

This site is temporarily password protected during the duration of the LHC workshop but will be re-opened immediately after the workshop.<\/p><\/blockquote>\n

I guess that CERN still wants the news of whatever is presented at Chamonix to first come from their press office, but realizes that making available the detailed technical discussion behind this news is a good idea.<\/p>\n","protected":false},"excerpt":{"rendered":"
