  1. NGAO ManagementUpdate Peter Wizinowich NGAO Meeting #11 November 5, 2007

  2. Project Reports • 4th & 5th reports submitted to Directors on 9/19 & 11/2 http://www.oir.caltech.edu/twiki_oir/bin/view.cgi/Keck/NGAO/SystemDesignPhasePlanning • Emphasis during this report period has been on: • System architecture evaluation & selection (June – Aug.) • Functional requirements (Aug. – Dec.) • Subsystem design (Sept. – Dec.) • Proposals to TSIP & ATI • Plus: completion of two performance budgets, incorporation of additional atmospheric characterization data, & summary reports for the performance budgets & trade studies

  3. System Design Milestones Requirements  Performance Budgets + Trade Studies  System Architecture + Functional Requirements  Subsystem Design + Functional Requirements  Management Plan 4 milestones completed since June SSC meeting

  4. Schedule & Budget Schedule: 53% of System Design Phase work complete through Oct.

  5. Schedule & Budget Budget: 64% of System Design Phase budget ($730k) spent through Sept. • 92% of the $798k FY07 budget, excluding $20k contingency Plan needs to be reviewed to ensure deliverables complete for SDR

  6. Schedule & Budget

  7. TSIP & ATI Proposals • $2M TSIP proposal for NGAO preliminary design submitted on Aug. 31 • $2M request to fund ~70% of preliminary design • Detailed schedule/budget to be determined during system design • $1.1M ATI proposal for deployable near-IR integral field spectrograph system design submitted on Nov. 1 • Proposed to ATI program because • Most complex NGAO instrument, with longest lead time • Advanced nature of key components made it suitable for ATI • System design scheduled from May/08 to Dec/09 • Proposal writing in both cases led by Adkins with support from WMKO management & NGAO EC

  8. Design Teams • AO opto-mechanical (Lead - Gavel) • AO wavefront sensors (Velur) • AO operational tools (Neyman) • Laser facility (Chin) • Controls (Johansson) • Science operations (Le Mignant) • Work scope planning sheets (21) produced for all major design tasks • Define tasks, approach, inputs, products & personnel • Ensure agreement on scope • Some approvals are still pending

  9. WSPS Status All but the following WSPS have been approved: • AO opto-mechanical • 3.2.1 AO system architecture • ? • 3.2.2 AO enclosure • Revisions requested • 3.2.3 AO opto-mechanical • Revisions requested • AO operational tools • 3.2.3.12 PSF monitoring camera • Revision received, but effort has grown by 20h • Controls (Johansson) • 3.2.4.1 & 2 Non RTC software & electronics • Revisions recently received • Science operations (Le Mignant) • 3.4.2.1 & 2 AO-Instrument operations architecture & optimization • Low priority since WSPSs for currently active WBS approved

  10. Summary • Major milestones, except for science/system requirements, are being met • Good progress on functional requirements & database to maintain them • Schedule is starting to slip. • EC will be reviewing schedule & deliverables to ensure SDR is held on schedule & within budget
