(3) ATF2 organization (Tauchi) http://lcdev.kek.jp/ILC-AsiaWG/WG4notes/meeting/2005/0126/tauchi.pdf - ATF2 WG's in KEK were proposed: (a) Optics, tuning and commissioning ; lead by S.Kuroda (b) Magnets and vacuum ; lead by T.Tauchi (c) Alignment and supports ; lead by R.Sugahara (d) Instrumentation ; lead by Y.Honda (e) Conventional facility ; lead by J.Urakawa (f) Optional facility ; lead by T.Takahashi - Each WG consists of a few sub WG's. [Discussion] - We have to consider our schedule of design and production.
