Fp420 versus dfb atm

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

FP420 Manchester Workshop - December 2006


Pre design version 1

Pre-design Version #1

  • Dipole cold foot to replace compensation system

  • Couple two DFB ATM

  • Allow contraction of the BB line

FP420 Manchester Workshop - December 2006


Pre design version 2

Pre-design Version #2

  • Redesigned supporting beam

  • Double cold feet to free space for line X

FP420 Manchester Workshop - December 2006


Version 2 displacement analysis

Version #2 – Displacement analysis

VACUUM CONDITION

FP420 Manchester Workshop - December 2006


Version 2 displacement analysis1

Version #2 – Displacement analysis

VACUUM CONDITION + INTERCONNECTION at cold (operation conditions)

FP420 Manchester Workshop - December 2006


Version 2 reaction analysis

Version #2 – Reaction analysis

Cold condition

(vacuum, bellow force)

Bellow force

- 10’000 N

Reaction y

55’000 N

Reaction z

70’000 N

Reaction z

- 32’500 N

FP420 Manchester Workshop - December 2006


Pre design version 3

Pre-design Version #3

  • Two lowered supporting beams

  • One single piece

FP420 Manchester Workshop - December 2006


Version 3 open issues next steps

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

FP420 Manchester Workshop - December 2006


Construction processes involved

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

FP420 Manchester Workshop - December 2006


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

FP420 Manchester Workshop - December 2006


Cost drivers what helps cutting them

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

FP420 Manchester Workshop - December 2006


Cern ts mme experience on dfb atm

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

Results:

Early deliveries and costs below expectations after the 3 first units

Conclusions

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
