TSIP & ATI Proposals
•
$2M TSIP proposal for NGAO preliminary design submitted on Aug. 31
–
–
•
$1.1M ATI proposal for deployable near-IR integral field spectrograph
system design submitted on Nov. 1
–
–
•
$2M 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

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

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 20h

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
