1 Prototype Review 04-Sept-2008

2 Different side-closeout to allow petal end-insertion concept…self- guided… Only backup from last review in July…

3 First thoughts… End insertion mechanism by self- guided rails would be interesting… How do we assemble the petals in here?

4 New concept… (from David Lynn) We still need to check if the end-insertion is possible with this system… taking into consideration that the petal it is not squared… The main advantages: -CF tubes are supplied by vendor… -Mass and Radiation length advantage… -Others…

5 CF TUBES HOLES FOR POSITIONING-PINS SI SHAPE ALREADY MODIFIED. DUMMY SENSORS WILL BE READY MIDDLE-END SEPTEMBER CLEARANCE BETWEEN HONEYCOMB AND REST OF COMPONENTS INCREASED TO 0,125” IMPROVEMENTS FROM LAST REVIEW…

6 CF TUBES HOLES FOR POSITIONING PINS ASSEMBLY TOLERANCES POCOFOAM & HONEYCOMB… HONEYCOMB THICKNESS STRAIGHT POCOFOAM CURVED POCOFOAM SS TUBE: OD: 0,109” ID: 0,085” FIXED DIMENSION FROM VENDOR CONTINUE IMPROVEMENTS AND MODIFICATIONS…

7 FIRST THOUGHTS FOR TOOLING… (FROM CARL AND GIL TEAM…) http://phyweb.lbl.gov/atlaswiki/index.php?title=ATLAS_Upgrade_RandD_-_Mechanical_Studies#Drawings_and_Procedures HOLES FOR ALIGNMENT VACUUM CHUCK FACING ALIGNMENT HONEYCOMB PLATE NEXT TODO: TECH. DRAWINGS FOR TOOLING
