FP420 versus DFB ATM Pre-design Version #1 Pre-design Version #2 Mechanical analysis Pre-design Version #3 Open issues

Advantages with CERN TS/MME Required framework conditions

Main processes involved Schedule and possible lead times Cost drivers DFB ATM assembly experience



FP420 versus DFB ATM

Continuity of the X and C lines Higher contraction of the busbar lines Fixed point to be relocated Longer interconnection bellow length Detector constraints (accessibility, precision) Radiation shielding

ArcTerminationModule

DistributionFeedBox

FP420Cryostat



Pre-design Version #1

Dipole cold foot to replace compensation system Couple two DFB ATM Allow contraction of the BB line




Redesigned supporting beam Double cold feet to free space for line X



Version #2 – Displacement analysis

VACUUM CONDITION



Version #2 – Displacement analysis

VACUUM CONDITION + INTERCONNECTION at cold (operation conditions)



Version #2 – Reaction analysis

Bellow force

- 10’000 N

Reaction z- 32’500 N

Reaction y55’000 N

Reaction z70’000 N

Cold condition(vacuum, bellow force)




Two lowered supporting beams One single piece



Version #3 – Open issues & next steps

Detector supported by the cryostat: need to deal with movements during cooling down and operation

Need of additional central fixed point and supporting jack

Use the transport buggies and the lifting beams of the DFBAs

Pre-design v#3 approval awaited



Construction – Processes involved

Machining (both heavy and accurate) Sheet metal forming (vacuum tanks, piping) MIG/TIG welding Thermal treatments / Surface treatments Mechanical fitting (Beam screen integration) Metrology / Alignment Vacuum test / x-Ray inspection Thermal super-insulation Electrical insulation assembly and test

Schedule projection attempt

Green light needed on time to allow the design work to start

The production cannot start before the design is fully

approved



Cost drivers – What helps cutting them

Re-use existent designed parts (cold feet, jacks, dished heads, etc)

Experienced and multi-skilled workforce Avoid specific tooling Optimize the logistics between operations



CERN TS/MME experience on DFB ATM

Design and mechanical analysis Full production and assembly of 16 ATM Budget and time constraints sealed in a

interdepartmental workpackage agreement

Conclusions

Advantages with CERN/TS/MME– Design and construction synergy benefits– Shortened learning curve (skilled resources and appropriate

equipment available)– Highly responsive multi-technological environment– Reduction of the logistics time and cost– Design and construction traceability (CDD/ EDMS / MTF)

Required framework conditions– Obtain the formal approval of the pre-design– Obtain the final version of the technical specification– Adopt a workpackage oriented approach combining the

mechanical design and the construction



The CERN TS/MMEMechanical and Materials

Engineering group received the

Golden Hadron Award(LHC best suppliers)

Fair and efficient partnership with CERN Member States

(here: Bulgaria)



Thanks for their contribution …
