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

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 ?

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

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

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
