  1. ILC CFS update for Europe J.Osborne / A.Kosmicki/ B.List – March 22th2012

  2. TDR progress for Klycluster Scheme on the CERN Site • Several machine lattice files received from DESY EDMS (Benno List) February 2012 • CERN draughtsman (Antoine Kosmicki) has spent 2 weeks putting these files together in order to generate a 3d model for the 500GeV machine • Using this 3d model and Autocad files from FNAL for Kycluster scheme, an attempt has been made to size the underground enclosures, optimised for the CERN geology. • Once ‘approved’ this new civil engineering layout will be costed by AMBERG Engineering (same company costed RDR for Europe, CLIC and also works on XFEL) • Interaction Region Studies by ARUP for CERN site are now finished. Final report today.

  3. Only e- side fully modeled (Positron Source). Impossible to model the entire machine in CATIA, which is ‘limited’ to 15km. Local co-ordinate systems needs to be created to have the entire machine into one model. ILC Project

  22. Typical Main Linac Cross Section for Klycluster Scheme on the CERN Site 1153mm Beam to floor = 1100m

  23. Most important drawing for CFS costing : Needs checking !

  24. CERN TDR efforts for Klycluster Scheme… Next Steps • These layouts will be used for ILC Europe civil engineering costing purposes and for : • Europe Scheduling exercise (Martin Gastal & Katy Foraz) • Handling & Installation studies (Keith Kershaw) • Survey & Alignment (Helene Mainaud Durand) • Safety requirements (Fabio Corsanego) • Exact Scope of what is to included in these chapters needs to be defined. • Environmental Impact Studies are ongoing for a LC at CERN (with the help of a technical student Caroline Waaijer).

  25. BACK-UP SLIDES

  26. STEP file imported into Catia from DESY to CERN thru EDMS (Courtesy of Benno List and Don Mitchell) Even such large models can now be downloaded and put in other 3D programs

  27. Just like in the LHC UJ22 cavern, The magnets will have to be lifted Over the beam lines

  28. Environmental Impact Assessment (EIA) • Required by French and Swiss law • Feasibility issue • 3 phases • Screening: establish necessity for EIA ( ) • Scoping: conduct EIA • Review: before submission • Required knowledge • Legal framework • Policies & decision-making • Engineering • Environmental impact criteria • Biophysical, socio-cultural, socio-economical

  29. Environmental Impact Assessment • Major issues for ILC: • Civil Engineering • Excavations, spoil dumps, soil swelling, hydrology, release pollutants geothermal drillings, hydrocarbons, visual impact… • Energy consumption • Focus on renewable & sustainable energy • Water consumption • Where discharged? • Focus on renewable & sustainable energy • Social acceptance • Impacts during and after constructions, fear • Waste • Radiation Feasibility threats

  30. Environmental Impact Assessment • Next steps • Planning • Task division • cost estimates EIA • Land acquisition • Start • Work together with Swiss / French authorities • In-depth studies • Identify knowledge gaps • Address feasibility threats
