  1. Experimental area layout : HVAC issues J.Osborne GS/SEM, Mauro Nonis EN-CV and M.Gastal EN/MEF for CES Working Group martin.gastal@cern.ch

  2. First draft concept for the ventilation of the CLIC Experimental Area See M Nonis’ presentation Emergency escape tunnel Machine By-Pass added Survey gallery added martin.gastal@cern.ch

  3. SUMMARY – 5 Ventilation Areas to be considered martin.gastal@cern.ch

  4. Assumption critical for the concept to be validated: → The airtight sealing of both experimental caverns should maintain a leak rate compatible with the establishment of a pressure differential with respect to the interaction region → Use of mobile shielding in conjunction with inflatable seal and fire proof seal (TX54) martin.gastal@cern.ch

  5. Assumption critical for the concept to be validated: → The airtight sealing of both experimental caverns should maintain a leak rate compatible with the establishment of a pressure differential with respect to the interaction region → Major challenge to make the mobile cable chains airtight martin.gastal@cern.ch

  6. The detector would be moved into beam position on a moving slab • Idea: • Area between the slab and the trench hosting the cable chain has to be airtight • Trenches will have to be closed in an airtight fashion martin.gastal@cern.ch

  7. Additional issue for discussion: Add a new machine shaft and cavern Shaft + Cavern would allow: Space for machine equipment Connection with water transfer tunnel Take the bypass off the volume of the experimental cavern Hosting of ventilation ducts for interaction region Installation of heavy vibration equipment Setup and removal of TBMs still being considered Water transport tunnel Lake GVA martin.gastal@cern.ch
