4. Surface Facilities: 904 zone A.Sharma, D. Hay

5. Surface facilities: 678 : 500m2 storage “tent” Critical to the logistics sequence of liberating ISR and re-equipping SX5 Nov 2011: another tent will be needed to clear tooling in ISR

6. ISR: conditions naturally stable enough Cut & fill tunnel-beam & expt slabs --> Floor stability excellent Temperature 21 ± 3 degrees C (for RPC 20 ± 2 is ideal) Relative humidity: 45 ± 10 % (For RPC 40 ± 5 % is ideal) Building mods & HVAC to achieve these conditions in all of 904 VERY expensive: CMS suggestion to use temperature-controlled internal lab enclosures with central HVAC

7. Alignment laboratory: DT , MAB + Link calibration benches No alternative location with similar stability identified so far –becoming urgent Tilt bench Link area Diagonal bench MAB storage area MAB transport box MAB calibration bench Camera calibration bench Chamber Alignment bench Move and re-survey cost estimate: 30k CHF 2009.03.12. Moving calib benches of the Alignment 7

8. 275 Ground floor: present layout

9. Plan for the ground floor Position sensor test bench MAB storage /Bench control Load zone Alignment benches • Remove walls of R-010 and R-006 • Probably keep the platform in the hall • Mobile (rolling, steel frames) MAB storage . • build new personnel door and a small SAS(temperature stability) • Camera bench and Barrel bench controls are in the MAB storage area • Large open space in front of Tilt bench to allow truck to get in to pick up MAB box • Possible location for 4T mini-magnet

10. 1st floor: present layout

11. Plan for the 1st floor • merge 1-008 and 1-006: office • merge 1-001 and 1-004 lab • extend balcony to 1-203 • move door of 1-001 • (if possible) keep platform in hall for storage office office B- sensor + camera Lab BFG (fibre)

12. Complication : Building structue • floor thickness is ~20 cm • floor is built up of independent slabs • ‘bunker’ to be filled up with concrete

13. Measurements and refurbishments • Intrinsic floor stability looks (surprisingly) good but must be measured in detail • Install Survey network • Vibration measurements while heavy vehicles go past the building, exit firestation • See if daytime use of the alignment benches is possible. • Revision of the full electric network • Revision and rethinking the HVAC for better year-round stability ~ ISR (removing the tower, and the piping at the back of the building) • Insulation of the building? • New personnel door near main access door , equipped with small SAS. • Change to faster opening main access door. • TOTAL needed: guess :400kCHF..awaiting estimates
