  1. C. Irmler (HEPHY), Y. Onuki (IPMU) Belle II – New Collaborators Meeting Ladder Assembly Procedure

  2. Introduction • Overview of the assembly procedure for a Layer 6 ladder. • Drawings and slides without HEPHY header are taken from Y. Onuki’s talk, presented at the14th B2GM in March 2013 • Procedure recently tested @ IPMU • Pictures from test assembly and new ideas added • Modification of some jigs and steps is in progress C. Irmler (HEPHY), Y. Onuki (IPMU)

  3. Ladder Assembly – Organization • Sharing of production: • L3: Melbourne – 7 + spares (2 sensors each) • L4: Tata (at IPMU) – 10 + spares (3 sensors each) • L5: HEPHY Vienna – 12 + spares (4 sensors each) • L6: Tokyo (IPMU) – 16 + spares (5 sensors each) • Contract between Tata and IPMU is being prepared • Interest of Italian groups (ex-SuperB) to join ladder assembly M.Friedl (HEPHY Vienna)
