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 cm185 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 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
