Dear Colleagues, The cost of the ILC has been in the news recently. The University of Chicago Magazine, in its Nov/Dec 2007 issue, has an article titled "Fermi's x factor." It discusses both Project X and the ILC in the context of the future of Fermilab. It characterizes the ILC as a "... long-range, worldwide plan to build a $15-$28 billion 35-kilometer accelerator...". You can read the full article at: http://magazine.uchicago.edu/0701/chicago_journal/fermi.shtml In a Letter to the editors of Physics Today which is titled "The true cost of the ILC", Dr. Michael Riordan questions not only the cost, but also the costing process. You can read this letter online at: http://scitation.aip.org/journals/doc/PHTOAD-ft/vol_60/iss_11/10_1.shtml It is not clear where the two writers got their information. The ILC value estimate and the costing process which was used has been very clearly and publicly stated.
