BEGINRELEASENOTES

  • FCCee_o2_v03: Copy of FCCDetectors FCC_o2_v03, and renaming of XML files to make diff with existing models easier, this model is obsolete

  • FCCee_o2_v04: Copy of FCCDetectors FCC_o2_v04, and renaming of XML files to make diff easier

  • CLD_o2_v05: New implementation of the CLD detector with small beampipe design according to latest standard design; modified vertex detector to fit into the beampipe constraints (reduced length of all barrel layers, based on FCCee_o2_v02 from k4Geo); fixed overlaps in Inner and Outer Tracker

ENDRELEASENOTES

Todo:

  • Create a CLD_o2_v05
    • with more accurate current beam pipe design
    • updated Vertex Detector Geometry
    • and removed overlaps
  • Waiting for the correct Paraffin material for the Beampipe

Do we still need an ID for the HOMAbsorber if we no longer have a HOMAbsorber?

Hi @andresailer

I also agree with @armin-ilg that the central chamber should be described as 3 layers, but if it is technically challenging I think also the mixed material could work.
The overall dimensions seems ok to me, but I would like to suggest to keep the tungsten shielding in a separated file.

I am also working on the CAD model import for the beam pipe, I will try to make a PR this week, so that we have also the copper cooling sections and a more realistic profile for the conical/trapezoidal section (which now is circular, but in reality should be elliptical).

…umical and beampipe design with parafin cooling
The geant version in LCG_103 prints some verbose warnings about the
fourth TA Shield, this seems to be spurious and due to a faulty check
of rmin vs rmax? This only happens when the detector is drawn.
Overlap check is clean
Fix overlap of modules going outside the envelope by reducing the inner clearance to 149 mrad half opening angle
The number of modules around phi has to be the same for all radii, use the correct module to cover the complete phi angle
