3. 3 PX ‘material’ shaft LHCb workshop Visitor area (15% of the 70000 CERN visitors in 2011) Access control Control room

4. 4 Visitor area welcomed 15% of the 70000 visitors at CERN in 2011 The visitor area is shared with access/transport/recreational area. Major developments foreseen by the end of 2012.  The full VELO spare detector will be displayed. It will be the only place were Visitors will see a full LHC detector. Special display zone will be prepared by LHCb.  3D movie cinema room will be installed. The room will isolated from the noisy environment.  Short term LS1: The visitor flow is likely to be limited by the lack of space available  Long term >LS1: Control room will be freed (new building) to enlarge the visitor area

7. 7 4 offices 1 meeting room (20-25p) From 2015, 5 offices will be made available in the new CR building

8. 8 Bldg 156 was used for LHCb detectors assembly Now it is used  For Support to LHCb operation (spare storage and repair lab)  for R&D LHCb Upgrade  Storage of delicate equipment's. upgrade activities LHCb needs to free space in bldg 156 for upgrade activities (R&D and detector assembly).

9. 9 New Lab for upgrade SiPM & Optical test bench Assembly of tracker prototype For LHCb upgrade PH-Safety LHCb detector spares and repair labs Storage LHCb, Aegis, NA62

10. 10 Storage (Long term) LHCb urgently needs decent storage space, preferably at P8  To protect tools and equipment which are currently degrading outside  To fulfill pending requests, LS1 and long term needs  To free space in 156 for LHCb upgrade activities (R&D and assembly). Estimate: 400 m 2, heated, cherry picker access, and crane. Office (LS1) LHCb needs office space at P8, to host LHCb staff, users, and support group At least 5 offices (10p) from 11/2012 to 08/2014
