  1. F.Videbaek PXL geometry update

  2. PXL ladder • For realistic simulation it is essential to get the proper layout of ladders. • Starting point • SW model • Material budget from Leo

  3. Si-layer with inactive frames Al-Kapton Cable Carbon backing Layers of adhesive F.Videbaek; HFT structures and geometry

  4. Si 2 mil (0.0529%) 0.0677% sensor acrylic 2 mil (0.0148%) Al 0.7 mil (0.0124%) Al 0.7 mil (0.0124%) kapton 1mil (0.0073%) kapton 1mil (0.0073%) Al 0.7 mil (0.0124%) Al 0.7 mil (0.0124%) 0.079% 0.223 mm acrylic 2 mil (0.0148%) cable acrylic 2 mil (0.0148%) 10 mil carbon composite open weave (0.0587%) backer 0.2221% 4 mil silicon adhesive (0.0469%) 9.6 mil carbon composite sector beam (0.1017%) support beam TOTAL = 0.3688 % X0

  5. Cable • Note that cable layout is slightly different 2 layer Al with total 0.073%. • Implemented Cable si component in my scripts using TGeo. • Materials for this have proper Radlenght, there is more work to do on the proper materials for Geant.

  6. Ladders as implemented

  7. End and top view

  8. Radiation Length at 2, 3 and 9 cm radius
