Progress on CDR module design

Lots of issues appear often during integration !
CLIC Two-Beam Module Systems
The baseline solutions were defined for each technical system and a solution for CDR is available
The module design and integration has to cope with challenging requirements from different technical systems.

- Detailed RF design of WFM is needed (CEA collaboration)- “S-AS” – “S-AS” interconnection to be revised and arranged in accordance of RF design with module length

PETS Design & Integration
28-Feb-2011 From A. Cappelletti:Hi Alexandre,here is the final design of the coupler (step file, full geometry).
Mech. design of CC & On-Off mechanism to be revised. Actuator and its interface to be integrated.

RF Network Layout
Requirements:tolerance on RF phase change between DB and MB: ± 0.12 degWG interconnections between PETS and AS via CMF:X – shift: ± 0.25 mm, Y ± 0.5 mm, Z ± 0.5 mm, Twist: < 5°
Longitudinal cut-out of CMF
Recent modification of CMF to be integrated. The WG length must be optimized consequently.
CMF design (latest version, less sensitive to mech. Displacement)

Baseline: classical electro-magnetic design
(MB) IC – BPM – Vac. Chamber – Dipole – IC
Longitudinal cut-out of MB Quad region
MB BPM
DIPOLE CORRECTOR
Longitudinal space constrain for BPM and Dipole corrector integration and interconnections !!! (Qty: MB: ~151000 units.) - MB BPM mech. design to be finalized- MB Quads must be “re-designed” according to space availability.
VAC. CHAMBER

(DB) IC – BPM – Vac. Chamber – IC
ALTERNATIVE: DB tuneable permanent magnet solution is under investigation (Cockcroft Institute)
- DB Q support design must provide fast precise positioning and fixation of the magnet.- The overall check of the region must be done after implementation of recent PETS CC RF design

Alternative DB Magnet
- A few conflicts exist for the alternative Quad design.(Cockcroft and alignment group)

Supporting, pre-alignment & stabilization.
The main components of both beams are supported on girders linked to one chain all along the linac.
Lab test setup. B162/R-011
- Modification of cradle & actuators layout in order to provide a pure transversal plane for transport and installation.- Finalization of structures fixations design.- Design of transport fixtures and development of installation sequence.
MB Quad / cam movers / stabilization
Version for T1 (shortest) magnet

Vacuum Layout
- The alternative solution to be studied. Mini-Pumps fixed directly on each structure. No lateral stress on RF structures. - Sectorisation to be implemented into general layout.
