NGAO Project AO Budget

• AO Cost Estimate 35M ? 10M
• Estimation approach 1 Comparison to other
  systems
• Gemini-S MCAO - 18M in 03 dollars.
• Add 7M for 2 additional lasers 4 inflation ?
  29M
• Gemini-S GPI - 19M 6M reserve
• Add 15M for LGS subtract 5M for instrument ?
  35M
• TMT NFIRAOS - 25 for AO 24M for LGS
• Subtract 10M for simpler system ? 39M
• Estimation approach 2 Bottoms-up cost estimate

Estimation methods agree
7
NGAO Project Instrument Budget

• Cost Estimate 20M ? 4M for 1st three
  instruments

Instrument ROM Cost Anchor
Near-IR Imager 3M G-S NIR imager 3.5M 1 vs 4 H2-RG
Visible Imager 3M LRIS-R upgrade 1.5M camera/filters 1M SW 0.5M
Deployable NIR IFU 14M TMT IRMOS 42M for 10 IFU AO 1.6M/IFU for 6
Near-IR IFU 7M OSIRIS 5.5M new detector
Visible IFU 4.5M OSIRIS without full cryo, 4x4K deep depletion CCD, slicer
Thermal NIR Imager 3M Similar to NIR, smaller but more expensive detector

System Design Objectives

• Establish design approach that meets the
  scientific user requirements
• Establish discipline integrated engineering plan
  for the proposed design
• Understand technical risks, trade-offs,
  performance estimates, cost to completion
• Key deliverables
• Systems Requirements Document
• System Design Manual
• Systems Engineering Management Plan
• Systems Design Report

9
System Design Project Schedule

• Plan based on delivery of 4 key documents
• Plan includes schedule person-hours

10
System Design Project Schedule

• System requirements need science team effort
• Budget includes 3 graduate students 1 postdoc

11
System Design Project Schedule

• System design will utilize expertise resources
  at CIT, UC WMKO

12
System Design Project Schedule

• System Engineering Management Plan

13
SD Risk Assessment Management

• Detailed risk assessment spreadsheet produced
• 40 items identified during initial point design
  development
• Severity probability of each item indicated
  along with risk mitigation plan
• During system design each risk area will be
  further addressed as either part of the planned
  trade studies /or as part of risk assessment
• Risk management process includes balancing
  scientific technical performance, cost
  schedule

14
System Design Budget

• Cost Estimate 980k
• Basis
• 12400 hrs or 6.4 FTE eng/scientist 120k/yr
  770k
• 5500 hrs for 3 grad students postdoc 150k
• 40k for travel 20k for procurements
• Only 3 of total NGAO budget ? system design
  phase budget may be low
• Believe we have properly identified path forward
  have a clear idea of how to proceed
• A more detailed estimate will be prepared as
  individuals identified next level of detail
  added to plan

15
Management Status

• Observatory Directors plan to define the NGAO
  management structure
• More detailed NGAO system design phase planning
  awaits management structure resolution
• NGAO ready to become a real project

16
NGAO Project Next Steps

• NGAO is ready to become a real project
• Ready to begin system design phase
• The project needs the following key personnel
• Principal Investigator
• Project Scientist Science Team
• Project Manager
• Systems Engineer
• NGAO Project Scientist science team lead
  development iteration of science requirements
• Volunteer model unsustainable
• Need to take advantage of expertise resources
  at CIT, UC WMKO in system design
• Form NGAO Science Advisory Committee to provide
  high level science guidance
