CFS Introduction and Regional Overview• Overall Siting Approach was to Initially Identify a “Sample
Site” in Each of the Three Global Regions• Americas and European Sites Still Considered “Sample
Sites”• Asian Region has Identified Two “Candidate Sites”• All Regions Used the Same Beamline Lattice Design• Underground Enclosures were Tailored to Meet Local Site
Geologic and Topographical Conditions• Local Conditions Also Affected the Type of HLRF System
Used Americas and Europe Used the Klystron Cluster System (KCS) Asia Used the Distributed Klystron System (DKS)

1.7.1 Civil Engineering – Americas and European Regions (8)
• Tunnel Lengths for Both Regions are the Same Based on the Same Machine Lattice
• The Americas Region Used the Same Diameter TBM for Main Tunnel Drives and Drill and Blast Methods to Enlarge Enclosure Areas as Needed
• The European Region Uses a Larger Diameter TBM where Technical Equipment Requires a Larger Dimensional Space
• All Service Tunnels for Both Regions Use a Uniform Diameter TBM

Americas Region Areas of Refuge are Provided All Non-TBM Construction is
Considered a Cavern Fire-Protected Connections are
Required for Shaft Access Volumes for Sources are Mostly
Considered BDS Americas Interaction Region
has a Larger Footprint Shaft Construction Extends to
Tunnel Floor Level Shaft Base Caverns do not
Include Shaft Volumes
European Region Areas of Refuge are Not Needed Some Minor Tunnel Widening is
not Considered a Cavern Protected Shaft Access is not
Required Volumes for Sources are
Considered as a % of Total European Interaction Region is
More Compact Shaft Construction Extends to
Top of Base Cavern Shaft Base Caverns does Include
Shaft continuation Volumes

1.7.3 Air Treatment – Americas Region (1) • Two Separate Ducted Air Supply Systems Provide Conditioned
Air to the Tunnel Enclosures General Supply Air with 20% Fresh Air Emergency Supply Air to Areas of Refuge (AOR) When Needed
• The Tunnel Enclosure Serves as the Air Return to Ducted Returns at Each Shaft
• Conditioned Supply Air will Maintain Tunnel Air Temperatures at 86oF (30oC) – Temperature Stability +/- 1oC
• Damping Ring and BDS have Additional Fan Coil Units to Maintain Tunnel Temperature Due to Addition Heat Loading and Stricter Temperature Tolerances +/- 0.1oC

Summary• Regional Conditions have had a Large Impact on the
ILC Conventional Facilities Design• In Both the Americas and European Regions Civil
Design was Primarily Completed by In-House CFSPersonnel Supported by Outside A/E Consultants
• In the Americas Region a Complete Mechanical and Electrical Design was Completed by Outside
A/E Consultants Supported by CFS In-House Personnel
• Compared to the RDR the Overall Design Maturity has Greatly Improved in All Regions
