  1. ESAC Review of the high field dipole designMagnet structure design, manufacturing, assembly procedure and testsMarch 2012for EuCARD-WP7-HFM J.C. Perez on behalf of SMC collaboration team J.C. Perez

  2. Outline • Magnet structure design • Manufacturing status • Assembly procedure • Preparation for cold tests J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN)

  3. Magnet design J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN)

  4. Manufacturing status • Price inquiry for the structure launched in September 2011 • The order placed in November 2011 has been split between 3 European companies • Cold-mass to Aratz (Spain) • Coil-pack (& dummy coil) to Boessenkool (Netherland) • Axial compression system to Mectalent (Finland) • All detailed drawings have been approved in December 2011 • Delivery of all components is expected by middle of April 2012 J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN)

  5. Work in progress on components J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN) 2 sets of Bladders (60 and 75 mm *1600mm)will be produced @ CERN by end of May

  6. Assembly Procedure Coil layer 3-4 Fiber glass cloth filler J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN) Coil layer 1-2

  7. Gap Impregnation • 2 facing surfaces of the coils will be mold released • Gap between coils will be filled with 0.9 mm fiber glass cloth • Impregnation of the fiber glass using the coils as cavity • This will guarantee a perfect contact between the 2 coils • This technique will allow to separate the coils in case of failure of one coil J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN)

  8. J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN) Coil lifting tool Coil rotation tooling

  9. J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN) Assembly sequence of the coils in the vertical pads

  10. Coil-Pack assembly J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN) Coil-pack assembly Horizontal pads Coil-pack assembly lifting tool

  11. J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN) Coil-pack rotating tooling

  12. J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN) Coil-pack lifting tooling

  13. A CERN standard rotating device will be used to turn the magnet J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN) ½ yoke weight: 2400 kg

  14. Positioning the yoke J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN) The 2 half yokes will be aligned with no gap in between

  15. J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN) Sliding the aluminum shell

  16. J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN)

  17. An aluminum support structure will be used to clamp the magnet to the rotating device J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN)

  18. The flat surfaces of the two 1/2 yokes are in contact J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN)

  19. Two bladders will be used to push the ½ yokes towards the shell inner radius to allow gap keys insertion J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN) Standard hydraulic jacks can be used instead of bladders

  20. Gap keys will be inserted in the yoke gap J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN)

  21. The assembled parts will be rotated to horizontal position J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN)

  22. Yoke and shell will be transported to an assembly table J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN)

  23. INA type bearing rollers will be used to slide the coil-pack into the yoke J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN)

  24. The coil-pack will be transported to the assembly table J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN)

  25. The coil-pack will be pushed into the yoke aperture J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN)

  26. Detailed view of the coil-pack inserted in the yoke J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN)

  27. 3 vertical bladders will be used to lift the coil-pack and remove the rollers J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN)

  28. Coils loading operation Temporary keys will be inserted to center the coil –pack into the yoke aperture J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN)

  29. Horizontal bladders insertion J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN)

  30. Pumping horizontal bladders & insertion of horizontal keys J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN)

  31. Vertical bladders insertion J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN)

  32. Pumping vertical bladders & insertion of vertical keys J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN)

  33. Final configuration after loading operation J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN)

  34. Axial compression system J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN) Bladders operation to change coil pre-stress remains possible after assembly of the end plates

  35. Coils interconnection J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN)

  36. J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN) Magnet ready to be transported

  37. From horizontal to vertical position in SM18 J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN)

  38. J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN) Magnet in the cryostat

  39. Aluminum dummy coil assembly • The first mechanical assembly will be performed using aluminum blocks replacing the real coils • This will qualify the support structure, the assembly and loading procedure and validate the FEM • The aluminum dummy coils will be instrumented with strain gauges in the aperture • The way to cool-down the structure to 77 K in LN2 is under investigation J.C. Perez TE-MSC-MDT EuCARD WP7-HFM ESAC Review (CERN)
