The most closely held numbers in the report have been the cost estimates (see <a href=\"http:\/\/www-ilcdcb.fnal.gov\/cost_estimate_status.pdf\">here<\/a> for a document about the status of cost estimates that warns &#8220;don&#8217;t post cost estimates on public web or wiki sites!&#8221;).<\/p>\n<p>The cost estimate comes out to $4.87 billion for the technology components, $1.78 billion in site-specific costs, 13000 person-years of labor, and two detectors (no cost estimate for these).  In round numbers, roughly $10 billion.   The machine would consist of two 11km linacs end-to-end, with an interaction region in which two detectors could be moved in and out.  The biggest part of the cost is the cost of the linacs, which would accelerate electrons and positrons to tunable energies with collisions at center of mass energy between 200 and 500 Gev.    A possible future upgrade of the machine would take it to 1 Tev.<\/p>\n<p>The plan for the future is to start working on a &#8220;Technical Design&#8221;, a much more detailed design that would show exactly how to build the machine.  The hope is to make a decision on whether to build the ILC around 2010, based on what the LHC has found, and on how much progress CERN has made on the much more ambitious CLIC design.  Construction would take 7 years, so the earliest such a machine could be in operation would be around 2017.<\/p>\n<p>The full report is <a href=\"http:\/\/media.linearcollider.org\/rdr_draft_v1.pdf\">here<\/a>.<\/p>\n<p><strong>Update<\/strong>:  More at <a href=\"http:\/\/www.sciencemag.org\/cgi\/content\/full\/315\/5813\/746\">Science<\/a> magazine and the <a href=\"http:\/\/www.nytimes.com\/2007\/02\/08\/science\/08cnd-collider.html\">New York Times<\/a>.<\/p>\n<p><strong>Update<\/strong>:  Joanne Hewett has an excellent detailed <a href=\"http:\/\/cosmicvariance.com\/2007\/02\/08\/designing-the-next-big-machine\/\">posting<\/a> about this over at Cosmic Variance.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The &#8220;Reference Design Report&#8221; for the ILC was released today, and here&#8217;s a presentation about this from Barry Barish, the director of the ILC GDE (Global Design Effort).
