Action Items from the meeting. Status of Action Items as of xx/xx/xx.

(Tentative) Goals:

(Tentative) Agenda:

9:50 am Telecommunications check
10:00 am Management Report (Wizinowich) Management Report
- Review study overall progress, progress against milestones, and summary financial situation

11:00 am Systems Engineering Report (Dekany) Systems Engineering Report (.ppt)
- Review the status of all systems engineering deliverables.

11:30 am Trade Study Report: K- and L-band science (Bouchez) Report (.ppt)
- From the WBS Dictionary: Consider the relative performance, cost, risk, and schedule of different strategies for K and L-band science optimization. Compare a Nasmyth relay, an ASM & a separate lower-order Nasmyth AO cryo-system. Complete when performance estimates & strategy for K- & L-band observing documented.
12:00 noon Trade Study Report: GLAO for non-NGAO instruments (Flicker) Report (.ppt)
- From the WBS Dictionary: Consider the relative performance, cost, risk, and schedule of GLAO compensation using an ASM as a wide-field optical relay for non-NGAO instruments. Complete when expected performance benefit for each instrument documented.
12:30 pm Trade Study Report: AM2 (Wizinowich) Report (.ppt)
- From the WBS Dictionary: Consider relative performance, cost, risk & schedule of an NGAO implementation based on an ASM. Quantify the benefit of an ASM to both NGAO and non-NGAO instruments. Complete when NGAO baseline architecture selected.

1:30 pm Trade Study Report: Optical relay (Bauman) Report (.ppt)
- From the WBS Dictionary: Consider the relative performance, cost & risk of OAP, general 2-mirror & Offner relays. Consider image quality vs. FoV, pupil image quality & the flowdown of requirements onto the (variable distance) LGS wavefront sensor(s). Evaluate science path and wavefront sensor paths to 150? radius, while optimizing the design over a 90? radius (after confirming that these are the correct radii to consider). Complete when an NGAO baseline optical design is selected.
2:00 am Trade Study Report: NGAO vs. Keck AO upgrades (Wizinowich) Report (.ppt)
- From the WBS Dictionary: Consider the feasibility of upgrading one of the existing Keck AO systems incrementally to meet NGAO science requirements. Consider opto-mechanical constraints & upgradeability of embedded & supervisory control systems. Consider impact on science operations during NGAO commissioning. Complete when option assessment documented
2:30 am Trade Study Report: Interferometry Support Options (Neyman) Report (.ppt)
- From the WBS Dictionary: Consider the relative performance, cost, risk & schedule of feeding KI with NGAO or a repackaged version of the current AO system. Decoupling of NGAO from interferometer support may simplify & improve performance of NGAO. The feasibility of maintaining a version of the two current AO systems for KI use should be evaluated. Complete when NGAO baseline architecture selected.
