CES studies for CDR :
1. Tunnel cross section2. Injection Complex 3. BDS Layout4. Experimental Area Layout5. Summary

1.Tunnel cross section
John Osborne : GS-SEM Civil Engineering18 May 2009 3
4.5m tunnel for CDR as agreed in 2009
John Osborne : GS-SEM Civil Engineering18 May 2009 4
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 ?

Injection Complex 2009 Layout
John Osborne : GS-SEM Civil Engineering18 May 2009 14
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

‘Spiral descents’ removed

3. BDS Layout
Input mainly from :Rogelio Tomas GarciaEdda Gschwendtner
John Osborne : GS-SEM Civil Engineering18 May 2009
Main Beam Dumps
John Osborne : GS-SEM Civil Engineering18 May 2009
Tune-Up Dumps added

4. Experimental Area Layout
John Osborne : GS-SEM Civil Engineering18 May 2009
CLIC Detector hall layout developed by :A.GaddiH.GerwigA.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
John Osborne : GS-SEM Civil Engineering18 May 2009Overall layout updated (full symmetry)
John Osborne : GS-SEM Civil Engineering18 May 2009
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

CTC 19 May 2009 Summary
• With a 4.5m diameter tunnel, it appears difficult to accommodate all equipment
• 5.6m recommended by CES working group• More TBM’s of this diameter available will help with Project planning• Reduction in other costs due to more additional working space ? Space for
future requests….• Additional CE cost in the region of 150M CHF
Barcelona Metro under construction 6.6m machine external, inner 5.8m. With 0.1m tolerance on radius = 5.6m internal diameter.
