NGAO Management Update Peter Wizinowich NGAO Meeting #11 November 5, 2007

Project Reports • 4 th & 5 th reports submitted to Directors on 9/19 & 11/2 http: //www. oir. caltech. edu/twiki_oir/bin/view. cgi/Keck/NGAO/System. Design. Phase. Planning • 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 2

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

Schedule & Budget: 64% of System Design Phase budget ($730 k) spent through Sept. – 92% of the $798 k FY 07 budget, excluding $20 k contingency Plan needs to be reviewed to ensure deliverables complete for SDR 5

Schedule & Budget 6

TSIP & ATI Proposals • $2 M TSIP proposal for NGAO preliminary design submitted on Aug. 31 – – • $1. 1 M ATI proposal for deployable near-IR integral field spectrograph system design submitted on Nov. 1 – – • $2 M request to fund ~70% of preliminary design Detailed schedule/budget to be determined during system design 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 7

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 8

WSPS Status All but the following WSPS have been approved: • AO opto-mechanical – 3. 2. 1 AO system architecture • – 3. 2. 2 AO enclosure • – 3. 2. 3. 12 PSF monitoring camera • Revision received, but effort has grown by 20 h Controls (Johansson) – 3. 2. 4. 1 & 2 Non RTC software & electronics • • Revisions requested AO operational tools – • Revisions requested 3. 2. 3 AO opto-mechanical • • ? 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 9

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 10
