The plan for an &#8220;International Linear Collider&#8221;, or <A href=\"http:\/\/www.interactions.org\/linearcollider\">ILC<\/A> is now in its design phase, with work proceeding on a detailed design for a .5-1 Tev collider.  No one has yet figured out where this would be sited or how it would be financed.  The agencies responsible for this funding seem to have agreed to <A href=\"http:\/\/www.interactions.org\/linearcollider\/documents\/LCreport_2004.html\">put off a decision<\/A>  about going ahead with the project until 2010.  <\/p>\n<p>By that time there should be a couple years of data available from the LHC, and if the Higgs particle or superpartners are found, it would be clear whether the ILC design would have enough energy to study them usefully.  Also around that time is should be clear whether CERN&#8217;s more ambitious design for a linear collider, called &#8220;CLIC&#8221;  and perhaps capable of reaching 3-4 Tev, is really a feasible one.  If the decision is made to build the ILC design, the hope would be to have construction finished in 2015   (although this sounds overly optimistic to me), allowing several years of joint running of the LHC and ILC.  If no Higgs or superpartners are found, or their mass is too high, the decision would be made to concentrate on CLIC, with construction done at the earliest in 2021.<\/p>\n<p>Back in the present, the Tevatron at Fermilab is now seriously <A href=\"http:\/\/www.fnal.gov\/pub\/now\/tevlum.html\">back in business<\/A> after a long shut-down, recently reaching record values of luminosity.
