5. Sensors (1/2)  HPK  Large rectangular sensors:  130% of installed quantity delivered already  Will issue an extra order for ~15% more in 2013  Small rectangular sensors:  Design submission and order by November 2012  Delivery until June 2013  Construction database is being developed  First filled with sensor data (objects, measurements, transfers, …)  Then also other objects 1 October 2012M.Friedl (HEPHY Vienna): SVD Schedule5

6. Sensors (2/2)  Micron  Trapezoidal sensors:  3 wafers with new p-stop design delivered in August 2012, tested OK  Beam test + irradiation + beam test in October 2012  After analysis: series production order by December 2012  Delivery until August 2013 1 October 2012M.Friedl (HEPHY Vienna): SVD Schedule6

8. 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

9. 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

10. 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 2013 1 October 2012M.Friedl (HEPHY Vienna): SVD Schedule10

12. Mechanics  Detailed design for all layers (including L3) completed 1 October 2012M.Friedl (HEPHY Vienna): SVD Schedule12

13. 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!

14. 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: http://indico.mppmu.mpg.de/indico/getFile.py/access?contri bId=2&sessionId=2&resId=0&materialId=slides&confId=1877 http://indico.mppmu.mpg.de/indico/getFile.py/access?contri bId=2&sessionId=2&resId=0&materialId=slides&confId=1877 1 October 2012M.Friedl (HEPHY Vienna): SVD Schedule14

16. 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
