8. Ladder Assembly 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 24 September 2012M.Friedl (HEPHY Vienna): SVD Status8

9. Ladder Assembly  Single Origami modules (HEPHY, 2010 and 2011)  Double Origami module (IPMU, 2012)  Both: collaborative effort of HEPHY, IPMU and Tata 24 September 2012M.Friedl (HEPHY Vienna): SVD Status9

10. Ladder Assembly Milestones  Prototype  December 2012/January 2013: full L5 prototype ladder  Thereafter: final optimization of jigs  Series Production  L3 starts in July 2013  L4-6 start in September 2013  Duration 1 year for each layer  SVD Assembly  Starting in September 2014 @ KEK 24 September 2012M.Friedl (HEPHY Vienna): SVD Status10
