Progress on CDR module design


2

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.


7

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)


8

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


9

(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


10

Alternative DB Magnet

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


11

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


12

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.


13

Summary

Many issues still exist and will be addressed during TDR phase

- 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- Mech. design of CC & On-Off mechanism to be revised. Actuator and its interface to be integrated.- Recent modification of CMF to be integrated. The WG length must be optimized consequently.
