Kurt KrempetzBoulder Workshop 9/15/083 SiD Engineering Group-History Formed in the summer ’07 Meet via Webex on Wednesdays @10:00 (US Central Time Zone) ~ every other week If interested send me mail (Krempetz@fnal.gov) to get on meeting notice list.Krempetz@fnal.gov Meetings/Workshops –IR Workshop - Sept ’07 –ALCPG – Oct ’07 –SLAC SiD Workshop – Jan ’08 –RAL SiD Workshop-April ’08 –Warsaw Meeting-June’08

4. Kurt KrempetzBoulder Workshop 9/15/084 Pre-Engineering Meeting Well attended –~10 growing to ~20 people Many Ideas and Concepts Discussed Conceptual Design Phases –LOI Design Consistent with Simulation Studies –Baseline Design Latest ideas that have been put on paper –Optimized Design Ideas and work that still needs to be done and is a process that continues until a final design is required.

24. Kurt KrempetzBoulder Workshop 9/15/0824 Axial Displacements of Endwall for 11-200 mm Plate Geometry – Assumes endwall plates are azimuthally continuous mm “bumpers” provide load path for all endwall plates to innermost barrel plates, reducing endwall plate span. Bumpers occur every 45 degrees total axial force on endwall is ~117 MN
