  1. ILD Magnet & calorimeters integration meetingQuestions to be addressed 01-02 /02/2012 @LLR-LAL

  2. 1St session : Experimental Hall & Japanese site • Experimental Hall design status • New considerations induced by Japanese site specifications : • Incidence on the design of the hall, on the assembly of the detector, on its design. • Influence of seismic considerations : predominant effects of vibrations over mechanical deformations.

  3. 2nd session : Coil and Magnet System • Vacuum tank : • Thickness of the vacuum tank skin ( 60 mm continuously?) • Fixation to return yoke (suspension and tie rods) • Hcal rail support : welded on vacuum tank? • FEA calculations • Construction

  4. 2nd session : Coil and Magnet System • Vacuum tank : • Thickness of the vacuum tank skin ( 60 mm continuously?) • Fixation to return yoke (suspension and tie rods) • Hcal rail support : welded on vacuum tank? • FEA calculations • Construction • Coil : • conductor, winding, • Internal instrumentation • Return Yoke design( shape, thickness, Muons chambers…) • Update of stray field calculations ( FSP aera, no compensating coil)

  5. 3rd session : Calorimeters assembly and integration studies g • FEA : • Self load and in load deformations. • Definition of attachment points in the coil (azimuth and sizing) • TPC support emax = 1.69 mm

  6. 3rd session : Calorimeters assembly and integration studies • FEA : • Self load and in load deformation. • Definition of attachment points in the coil (azimuth and sizing) • SDHcal = room for these rails. ( also place for services)

  7. 3rd session : Calorimeters assembly and integration studies • FEA : • Self load and in load deformation. • Definition of attachment points in the coil (azimuth and sizing) • TPC support : • Azimuth, • fixation to Ecal/Hcal/Vaccum tank ? • Needed space ( on the face of TPC and on the other fixation point) • if time : • Not to forgot that 700 cables coming from the inners : way out in each case ( AHCAL/DHCAL/TPC endplate), connecting boxes

  8. 4th session : endcaps studies Segmentation of the Ecalendcap Tilt of the Ahcal ( 22.5 °) (because of self load deformation)

  9. 5th session : Hadronic calorimeters , design report Update of the design of the Calos Tooling SDHcal : dimensioning of the gap Calo/coil ( overlap of service, rails…)
