ILD Magnet & calorimeters integration meeting Questions to be addressed

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. 1St session : Experimental Hall & Japanese site

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

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)

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

 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) 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 3rd session : Calorimeters assembly and integration studies

4th session : endcaps studies Tilt of the Ahcal ( 22.5 °) (because of self load deformation) Segmentation of the Ecal endcap

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…)
