A two day checkout period is now underway, which should have the LHC ready for beam at 17:00 Friday.  Friday evening and night should see beams threaded around the machine in both directions.  Saturday the plan is to capture a circulating beam in one direction, Sunday in the other direction.  Celebratory drinks are scheduled for 17:00 Monday in the CERN Control Center.<\/p>\n<p><strong>Update<\/strong>:  Up-to-date news about beam commissioning is <a href=\"http:\/\/lhc-commissioning.web.cern.ch\/lhc-commissioning\/news\/LHC-latest-news.htm\">here<\/a>, and hopefully CERN won&#8217;t shut off outside access to it.
