1. Stavelet 09 and Storage/Assembly/Survey Frame Progress Report Brookhaven National Laboratory David Lynn, Susan Duffin, Anatoly Gordeev, Ken Sexton Yale University Paul Tipton, Thomas Hurteau, William Emmet 3/6/2016BNL/Yale1

2. Stave Frame Design Design by Yale with consultation from M. Gibson (RAL) and BNL via frequent phone meetings Design accommodates RAL approach (frame is just for assembly) and BNL/Yale approach (one frame per stave). More details of differences in approaches is described in ID strips Wed session at last AUW (D. Lynn) RAL targets in frame, BNL targets on stave We need information on EOS and BBC interferences. For example, size and placement of connectors on EOS Frame designed for z-insertion (end insertion) Stave frame structure is MIC-6 aluminum precision jig plate Details follow in next few slides RAL Frame Target 3/6/20162BNL/Yale

3. Clearances BNL Targets at corners EOS Proposed to now be 120 mm wide 3/6/20163BNL/Yale

4. Clearances (example) Example of clearance for PPB Need clearances for BBC and EOS Power Protection Board and clearances Height of main components (blue rectangles) in mm 3/6/20164BNL/Yale

7. Stave Storage/Survey Frame Details Frame structure is MIC-6 aluminum jig plate 19.1 mm thick (alodined); Two removable covers: top is clear anti-static polycarbonate (1.6 mm thick)- bottom is aluminum, also 1.6 mm thick; Survey fiducials are located on an 82.55 mm pitch along both sides; Stave is inserted along Z-axis following removal of plastic closeout and cooling tube strain relief bracket and is located in Z via tooling ball; Frame is designed to be used by both BNL/Yale and UK simply by switching from vee-pins (US) to “block” pins (UK); Cabling penetrations still need to be defined. 3/6/20167BNL/Yale

10. Stavelet09 Core Assembly 3/6/201610BNL/Yale Assembly of first core is underway: Dimensions are per June 2009 meeting at BNL (STAVE-09) We are using Allcomp carbon foam in lieu of POCO Thermal properties are closer to isotropic Easier to machine (more uniform) Assembly and QC should be completed by 12/18/09 Allcomp FoamPOCO Foam
