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

Integration of beamlines with building (N. Chritin) Goal is to integrate beam-lines, waveguides, optical lines, ventilation ducts, connecting holes between building etc. in a single 3D drawing (CATIA).

Milestones and Summary Building ready for installation of beamlines by mid 2007 TL2, TL2’ and TBTS to be ready for beam by April 2008 First experiment after commissioning is high power production with PETS in summer 2008 CALIFES can be commissioned in parallel Second experiment is two beam acceleration of CALIFES beam with high frequency structure powered by PETS in autumn 2008. 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 and we should foresee space for a deflecting magnet in CALIFES beam line CLEX is quite CompLEX
