Status of the LHC Project Luciano MAIANI CERN Council June 21, 2002

Council, June 21, 2002LHC Status2 1. LHC progress since October 2001 Contract for Cryogenic line: –adjudicated (Nov. 2001) –Signed Super-conducting cable production: –Reviewed by external Panel in Feb (all firms interviewed) –New production schedule defined and agreed Contracts for the assembly of the main dipoles: –Adjudicated ( Dec. 2001) –Defined and signed Civil engineering works – steadily progressing –Hand-over dates of the caverns to experimental Collaborations confirmed (ATLAS: April 2003, CMS: July 2004) LHC schedule redefined according to signed contracts Agreement on M&O costs reached with Funding Agencies

Council, June 21, 2002LHC Status3 LHC Schedule We are very unhappy that the 2006 schedule could not be held; Definite damage for many physicists and students around the world; New schedule is based on official dates in the contracts of the main industrial items, with some reasonable (but not so large) time contingency; Schedule determined by technical rather than financial constraints; Makes possible an overall affordable scheme, for both machine and detectors.

Council, June 21, 2002LHC Status4 LHC Cost to Completion We confirm the Cost to Completion given in 2001; A contingency >100M is included in the Medium Term Plan; The analysis of Manpower, in the framework of new schedule, savings etc. is in progress Attribution of (36) Work Packages to specific groups, responsible towards LHC/CERN Management has been going on and is now almost completed Earned value accounting, FI updated contract follow up are being implemented.

Council, June 21, 2002LHC Status11 Super Conducting cable, last concerns Breakage of one cabling machine has been announced early this week; 3-4 months to repair; CERN has ordered one cabling machine as backup, but it will come into operation in spring 2003 only; We shall ask companies to continue with strand production and use our stored capacity to provide sc cables for dipole cold mass production.
