CLEX Building key numbers
CLEX-A (Accelerator housing)Inside dimensions L x W x H = 42.5 m x 8 m x 2.55-2.65 m, no pillars inside building !
CLEX-G (Equipment Galery)Inside dimensions L x W x H = 22 m x 8 m x 3.45-3.54 m
Bottom line: July 2007, Building with infrastructure ready for move-in !

Estimate of number of 19” racks required for CLEX equipment
Equipment type Number of racks
Magnet power supplies 30
Ion pump power supplies 5
Vacuum gauges, valves and interlock controls 4
Low power 3 GHz RF 4
Modulator mains distribution 2
Controls, beam diagnostics, timing 3
Total estimate 48
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
