                                Other possibilities


• Fermilab beam line M-center
       – Is shorter, higher rates at low energies
       – same spill structure
       – MIPP continuation not approved, but other parties show interest,
         too.
       – Details being investigated


• CERN
       – SPS will run in 2006 (May - )
       – Informal contacts
       – Details being investigated

First statements on timeline of GDE

• Snowmass (2nd ILC meeting) is important
       – Fix ILC baseline configuration
       – Yet, keep open for improvements


• CDR target date: end of 2006
       – But: with price tag
       – Site dependent: sample sites
               • Understand geological / political constraints


• TDR in 2008
