1. Project Overview James Fast Pacific Northwest National Laboratory

2. 13-December-20132James Fast, US Belle II Technical Design Review Why we are here From O413.3b: “Complete and review the Final Design or determine that the design is sufficiently mature to start procurement or construction. The FPD will ensure a constructability review is completed as part of the Final Design.”

11. 13-December-201311James Fast, US Belle II Technical Design Review Charge to the Committee Technical Design Review of iTOP already held last week in Tokyo – Reviewed WBS 1.02 (iTOP quartz), iTOP readout portion of WBS 1.03 as well as iTOP integration – WBS 1.04 (KLM modules) already received CD-3A and are completed This review covers the remaining portion of WBS 1.03 (KLM readout system) and WBS 1.05 (commissioning detector). The review committee is asked to address the following: – The quality of the design. – Have the operational and functional objectives been met? – Is the design biddable, constructible, and cost-effective? – Interface compatibility. – Has a detailed, unbiased, analytical approach been used for all of the above items? I would appreciate receiving your committee's report within 30 days of the review's conclusion.
