Total rack space available 63

Enough space for all power supplies, vacuum, controls and beam diagnostics racks needed for CLEX beamlines

Space for two S-band modulators and klystrons

Neighboring CTF2 gallery has space for one or two more modulators and klystrons and for more electronic racks (i.e. for 30 GHz receivers for two beam test stand and drive beam test beam line)

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 !

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 inphases (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
