CERN L.Evans & C.WyssINFN CSN1 Napoli September Magnet Installation Installation is progressing in sectors 8-1 and 4-5. More than 100 superconducting magnets have been installed. The installation rate must now ramp up to 20 magnets per week (16 dipoles and 4 SSSs) in the next few weeks. At the end of October, sector 7-8 will be liberated for magnetic installation. From then on there will be no shortage of slots.

CERN L.Evans & C.WyssINFN CSN1 Napoli September Conclusions Main objectives: –terminate installation in February 2007 –first collisions in summer 2007 The industrial production of standard components is compatible with this objective. The ramping up of QRL activities and magnet installation is critical to maintain this schedule. Additional actions have been implemented to ensure proper QRL production and installation rates. The installation and interconnection of cryomagnets have started in the tunnel. The commissioning of technical systems will take place in two adjacent sectors in parallel. Main next actions: –partial test of sector 7-8 in autumn 2005 –commissioning test of the two first sectors (7-8 and 8-1) in summer 2006 –find external collaborators to help with commissioning. => many thanks to INFN for its support !
