  1. Inner Detector Material Description Stephen Haywood Rutherford Appleton Lab

  2. Status PP0 PPF1 • I thought we were in good shape – various people have worked on Material Description over the years. • Pixels: • Complete in Pixel Tracking volume; need Services from PP0 to PPF1 (|h| > 2.0) • SCT: • Complete up to and including PPF1 • TRT: • Complete up to and including PPF1 • Beampipe: • OK – although could be improved by merging 2 layers into 1 • https://twiki.cern.ch/twiki/bin/view/Atlas/InDetGeometryUpdate Stephen Haywood – Simulation WG

  3. PPF1 Stephen Haywood – Simulation WG

  4. SCT Stephen Haywood, Alessandro Tricoli, Pat Ward Stephen Haywood – Simulation WG

  5. Beyond PPF1 ? This is an ID Responsibility (rather than Pix/SCT/TRT) and is outside the ID volume. Was being looked at by a student (from LAr). There is a note: ATL-LARG-INT-2009-002 Several of us have looked at this note and cannot understand what has been done. The SCT (EC) PPF1’s & Heaters were implemented. There is the possibility that TRT PPF1’s were implemented twice (?!?). Some Cables/Pipes may have been implemented ....but unclear. Author has left ATLAS. In retrospect, not obvious where info was coming from and who was in charge. I have very little confidence in what has been done. Stephen Haywood – Simulation WG

  6. Material distribution for ID services in PPF1 Critical area is PPF1 (triangular section in drawing) Don’t have all Patch Panel numbers! - S. Haywood has provided numbers for SCT end-cap (34501.65 g). Thanks! - Don’t have Pixel and TRT so made a guess based on number of cables with respect to SCT!

  7. What now ? Andrea Bocci needs to understand status of TRT PPF1. I need to speak to Sigi Wenig and Andrea Catinaccio who were responsible for ID Services. Adele asked for Eng Drawings ... Do you really want these ? Who will implement ID Services ? I assume ID ! If we want to improve model of Beampipe (not obvious that it is necessary), Grant would like some help.
