STATEMENT OF PROBLEM
Transport and transfer/install :
• 20,000 modules and their supports along the
CLIC tunnel
• Install magnets etc on tunnel roof
• Install magnets etc between main beam line and
tunnel roof
• Install magnets in turn arounds
• Install other things like dump lines and services
• WHAT WE NEED NOW IS TO RESERVE SPACE AND
DEFINE INTERFACES
CLIC – Typical Cross Section
CLIC – CV issues
Monorail ?
No. & Diameter
of CV pipes
needs to
modified
Floor stability to
be studied
Transversal Ventilation ?
Overall module dimensions (April 2008)
New configuration
Alexandre.Samochkine @ cern.ch
MB: sealed acc. structures in disk
DB: PETS with “mini-tank”
Quadrupole - updated 3D model
Schematic CLIC Module layout
Accelerating structures:
based on CLIC-G disk
damped and sealed long
version
- in-out WG for 4 structures
- 980 mm, including 20 mm for
interconnection
MB front cradle hidden

tables
LHC cryodipole installation with
transfer table -2
LEP Installation “Lobster”
LEP installation “Lobster” 2
However
• No room for transfer tables or lobster frame
below modules

However
Lose a lot of height below monorail for:
• Rolling chassis
• Rotation elements
• Depth of lift arm structure
Centre of gravity of load MUST be under centre
of rail during transport (this is an unknown for
the modules)
Collimator installation with trailer
mounted crane
DUMONT
HERA Tunnel section with TRAM
However
• No room for stabilisers below modules
• Need space above handled loads for spreader
beams and arm structure

Summary - 1
• Need to determine module / support transport
configuration
• Transport zone needs to be wider than modules
/supports in transport configuration
• Need to consider transport and installation
• Transport solution should not require space under
modules (simple interfaces and passage zone)
• Need to reduce cycle times
• Consider transfer lines, turn arounds and beam dump
lines
Summary - 2
HERA TRAM – type solution
• Transport and transfer/installation combined
• Deals with roof-mounted magnets
• Possible to adapt for transfer over modules to
beam dump line?
