CLEX building Construction on schedule 31.8.2006 June 2006 25.10.2006 Construction on schedule Equipment installation from May 2007, Beam foreseen from March 2008 Jan 2007

Floor and Beamline Heights Tue to difference in construction technique CLEX floor is ~50 cm lower than combiner ring building and DB Linac building Beam height above floor DB Linac, delay loop, TL1 and combiner ring 135 cm 135 cm + 50 cm=185 cm seems too much for CLEX G Vertical bends needed in TL2 All beamlines inside CLEX are at the same level but CLEX G floor has a 1.5% slope for water evacuation therefore beam height above floor varies from 1.25 to 1.35m ! DB Linac 50cm CLEX

Refurbished from TSL, LURE and some new QL3 2 dipole magnets either refurbished from LURE Beam diagnostics (~6 BPM, 1 BPR, 1 WCM, 2 OTR) to be provided by CERN BPM electronics LAPP ? Vacuum systems to be provided by CERN (or RRCAT) Power supplies and cabling to be provided by CERN Mechanical design and supports to be provided by CERN Installation foreseen from October ’07 to March ’08 Interface definition to TBTS still required !

Milestones and Summary Building ready for installation of beamlines by mid 2007 TL2, TL2’ and TBTS to be ready for start-up spring 2008 CALIFES can be commissioned in parallel First parts of TBL to be tested in 2008 but construction will happen in phases (see Steffens talk). ITB is for time being an option for which we reserve floor space
