[[%ATTACHURL%/Meeting_5_Action_Items_Status.doc][Status of Action Items]] as of xx/xx/xx. (Tentative) Goals: * Review Project Status * Review recent Trade Studies (Tentative) Agenda: * 9:50 am Telecommunications check * 10:00 am Management Report (*Wizinowich*) [[%ATTACHURL%/filename.ppt][Management Report]] * Review study overall progress, progress against milestones, and summary financial situation * 10:30 am Science Team Report (*Max*) [[%ATTACHURL%/filename.ppt][Science Team Report]] * 11:00 am Systems Engineering Report (*Dekany*) [[%ATTACHURL%/filename.ppt][Systems Engineering Report (.ppt)]] <!-- [[%ATTACHURL%/filename.pdf][(.pdf)]]--> * Review the status of all systems engineering deliverables. * 11:30 am Trade Study Report: K- and L-band science (*Bouchez*) [[%ATTACHURL%/filename.ppt][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*) [[%ATTACHURL%/filename.ppt][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*) [[%ATTACHURL%/filename.ppt][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. * 1:00 pm *Break* * 1:30 pm Trade Study Report: Optical relay (*Bauman*) [[%ATTACHURL%/filename.ppt][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*) [[%ATTACHURL%/filename.ppt][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*) [[%ATTACHURL%/filename.ppt][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. * 3:00 pm Upcoming tasks and milestones (*Wizinowich*) [[%ATTACHURL%/filename][.ppt]] * 3:15 pm Discussion: Issues pertaining to ongoing and upcoming work (*All*) * 4:00 pm Adjourn
