Ladder Production Sites Discussion among all parties during summer 2012 B2GM Plan for sharing of production: L3: Melbourne L4: Tata (at CERN due to export restrictions) L5: HEPHY Vienna L6: IPMU We also agreed that it is important to keep some flexibility in our plan, so that one site can help another if trouble/delay occurs 1 October 2012M.Friedl (HEPHY Vienna): SVD Schedule8
Origami Prototype Modules Single Origami modules (HEPHY, 2010 and 2011) Double Origami module (IPMU, 2012) Both: collaborative effort of HEPHY, IPMU and Tata 1 October 2012M.Friedl (HEPHY Vienna): SVD Schedule9
Ladder Production Schedule Full ladder prototypes (L5 & L6) by February 2013 Followed by final optimization of jigs Series production for ~1 year starting summer/autumn October 2012M.Friedl (HEPHY Vienna): SVD Schedule10

Mechanics Detailed design for all layers (including L3) completed 1 October 2012M.Friedl (HEPHY Vienna): SVD Schedule12
Mechanics: Minor Open Issues Ladder mount on end rings Not finalized yet, but converging Prototypes being prepared Cooling for L3 hybrids heat pipes look promising, now investigating 1 October 2012M.Friedl (HEPHY Vienna): SVD Schedule13 Acknowledging help from MPI & DESY engineers!
Mechanics Schedule Overview: Overall design is completed Ladder mounts to be finalized by end of 2012 Carbon fiber rib prototypes now being produced Support cone prototypes in August 2013 End flange prototype by March 2013 Detailed SVD mockup by March 2013 See slides from recent SVD-PXD meeting for more details: bId=2&sessionId=2&resId=0&materialId=slides&confId= bId=2&sessionId=2&resId=0&materialId=slides&confId= October 2012M.Friedl (HEPHY Vienna): SVD Schedule14
1 October 2012M.Friedl (HEPHY Vienna): SVD Schedule15 Sensors Ladder Production Mechanics Cooling Electronics Summary
Cooling CO2 system in Belle II does not need inspection by Japanese government (capacity is too small) Will be operated by the KEK cryogenics experts Cooling Mockup at DESY Operated with XFEL CO2 unit (similar to MARCO which will become available by the end of 2012) Distribution & Routing of cooling pipes Number of lines is defined First design for manifolds and routing exists 2 options for transfer lines (3 pipes in larger one or pipe-in-pipe) APV25 cooling contact is converging 1 October 2012M.Friedl (HEPHY Vienna): SVD Schedule16
