2. News from CTC 18 May 2010 on CLIC tunnel cross section
3. CDR Authors for CES studies
John Osborne : GS-SEM Civil Engineering18 May 2009
Report on behalf of CLIC Civil Engineering and Services (CES) WG
CTC 18 May 2010
CES studies for CDR :
1. Tunnel cross section
2. Injection Complex
3. BDS Layout
4. Experimental Area Layout
5. Summary
John Osborne : GS-SEM Civil Engineering18 May 2009
1.Tunnel cross section
John Osborne : GS-SEM Civil Engineering18 May 2009 4
4.5m tunnel for CDR as agreed in 2009
John Osborne : GS-SEM Civil Engineering18 May 2009 5
Drawbacks with 4.5m tunnel identified in 2009
• Positioning of electronic racks not ideal• Solution : Re-position onto tunnel floor, but possibly means deleting safety barrier
• Difficult to access ‘tunnel wall’ side of modules• Solution : remove entire module for access ?
• Access to Drive Beam dumps • Solution : Local Tunnel enlargement to allow ‘ladder’ access (see next slides)
• Impact from vibration from floor embedded pipes• Solution : Further studies in TD Phase
• Reduced space due to transversal ventilation and perhaps not sufficient cooling power • Solution : Study longitudinal ventilation system during TD Phase
• No space for vehicle powering ‘monorail’ and integration conflict• Inductive powering for vehicle ?

2. Injection Complex :Input mainly from :
L.Rinolfi
B.Jeanneret
F.Stulle

Injection Complex 2009 Layout
John Osborne : GS-SEM Civil Engineering18 May 2009 15
Injection Complex 2010 Layout
• 1.1km extra tunnel for turnarounds
• 500m extra for CR, DR
• Injection cut and cover tunnels lengths increased to 1.4km (from 1km)
‘turnaround’ is now a horizontal cut/cover design
John Osborne : GS-SEM Civil Engineering18 May 2009
‘Spiral descents’ removed
John Osborne : GS-SEM Civil Engineering18 May 2009 17
Surface tunnels / halls for Injection Complex
2010 Layout : Surface buildings added

4. Experimental Area Layout
John Osborne : GS-SEM Civil Engineering18 May 2009
CLIC Detector hall layout developed by :
A.Gaddi
H.Gerwig
A.Herve
CES will now use this as starting point for CE & services design, including cost estimates
John Osborne : GS-SEM Civil Engineering18 May 2009
Machine By-Pass added
Survey gallery added
Emergency escape tunnel
Better to delete cavern ‘technical alcoves’
Gantry crane capacities to be determined
CV being consulted about requirements
John Osborne : GS-SEM Civil Engineering18 May 2009
ILC 3d models developed at CERN using CATIA :
CLIC models to follow once draughtsman is identified

5. Summary
• Will continue to try and ‘freeze’ CE layouts at monthly CES meeting. Next major issue is amount of space required for Power Converters.
• Martin Gastal is gathering input from other technical services for experimental hall (CV,EL etc)
• Costing for CDR required for all technical infrastructure by September with assistance from Amberg consultants (same CE consultants for ILC)
• Draft layout for CDR Chapter ‘Civil Engineering and Services’ has been submitted to Hermann
• Next CTC 22 June specifically about tunnel cross section (4.5m,5.2m or 5.6m)
John Osborne : GS-SEM Civil Engineering18 May 2009
5.6m first DRAFT
