  1. Instrumentation ProgramSAC meeting, Dec 13-15, 2006 David Crampton TMT.IAO.PRE.06.046.REL01

  2. This talk • First light instrumentation (including AO) cost estimates • Plan for development of future instrumentation • Silva cartoon of development costs • General comments on instruments 3 - N • Requests to SAC TMT.IAO.PRE.06.046.REL01

  3. First Light Instrument Cost Estimates • Detailed IRIS and WFOS cost estimates were developed for the Cost Review • Based on plan that these first two “construction fund” instruments: • will be built by consortia of “internal partners” working with external collaborators. Shared projects => more mgmt and sys eng • Conceptual designs will be completed before end of DDP • IRIS will be first integrated and tested together with NFIRAOS at NFIRAOS supplier site. • IRIS + NFIRAOS will be commissioned together on telescope when M1 complete • WFOS integration and testing on summit will begin in 2015 before M1 is completely finished TMT.IAO.PRE.06.046.REL01

  4. AO & INST COSTS ($2006)(construction funds only) In addition to this, the cost of the Project Office oversight, systems engineering, commissioning activity & lab equipment is $8.0M, without contingency. The total of all instrumentation and AO activity is $114.5M, without contingency and without AM2 studies. TMT.IAO.PRE.06.046.REL01

  5. Summary: first light instruments • Two instruments (IRIS and WFOS) ready for first light in 2016 • Realistically, two good working instruments are likely to be adequate for the limited amount of science time in first year or so. • An advantage of this plan is that there is no need to commit to detailed requirements for next phase of instruments until after construction begins. • Requirements for next two instruments needed in 2009 • Commission these two starting in 2018 Jan TMT.IAO.PRE.06.046.REL01

  6. Future Instrumentation • Our current strategy is to deliver two instruments from construction funds and fund remainder from operations/development funding • A scenario for this development activity is outlined in “Instrument Development Plan: Post Construction Budget” TMT.IAO.COR.06.005.REL01 http://project.tmt.org:8080/docushare/dsweb/Get/Document-6974/Instrument Dev_OPS_3.doc • Assumptions: • Competitive: project will fund two conceptual designs for each of the instruments that will satisfy the scientific requirements and result in firm price quotations • Cycle time is 8-9 years from initial RFP to end of technical commissioning (although only 5-6 years to “build”). TMT.IAO.PRE.06.046.REL01

  7. Development Plan for Future Instruments • 2009 Dec: SAC redefinition of instrument suite complete • Establish funding envelope for next phase of instruments. • Ideally would need ~$25M per year to fund all the AO and instrument activity requested in SRD • Typical stand-alone instruments cost ~$20-60M; some NFIRAOS instruments are less • 2010 Jan: Begin conceptual design phase of second pair of instruments. • 2012 Jan: Conceptual designs completed • 2018 Jan: Instrument 3 commissioning begins • 2019 Jan: Instrument 4 commissioning begins • Repeat cycle for instruments 5&6 etc., starting in 2013 TMT.IAO.PRE.06.046.REL01

  10. Constraints & Assumptions • Constraints = Board mandates • No new money until 2012 • Total available new money = 200 M$ (2006) • Not certain that all new money will be available for instruments • No more than 20 M$ per year • Assumptions = mutable • First two instruments + NFIRAOS + LGSF from Construction • AM2 not included anywhere • Eight years from preliminary SAC discussion to AIV/Comm • No more than one new start per year • No more than one commissioning cycle per year • Unit cost: 25 M$ TMT.IAO.PRE.06.046.REL01

  12. Cartoon Model – II Integrated: 175 M$ TMT.IAO.PRE.06.046.REL01

  13. Discussion • Support NFIRAOS + LGSF investment • Range of possibilities, range of cost (10 M$ – 50 M$ per thing) • Need Instrument Development Roadmap • SRD vision update • Framework for science case for construction proposal(s) • Framework to attract “instrument donors” and “instrument associates” • Must commit to First Suite this year • Needed for coherent Construction proposals • The roadmap cannot be cast in stone… • Not necessary (or desirable) to lock-in exact future sequence now • Need to be sensitive to developments in astrophysics and technology • Roadmap should be reviewed and revised annual by SAC TMT.IAO.PRE.06.046.REL01

  14. Comments about instrument suite TMT.IAO.PRE.06.046.REL01

  15. Comments on instruments 3 & 4(Start in 2010; commission in 2018-9) • PFI should be able to attract independent funding • $29.4M, largely based on detailed GPI costing • GPI (and ESO equivalent) will be in I&T phase in 2010, first light 2011 - should be a good basis for PFI start in 2010 • Strategically, should build on NFIRAOS + LGSF investment (NFIRAOS will only remain state-of-the-art for ~ decade) • IRMOS-NFIRAOS • Multi-slits like MOSFIRE? • 6 deployable IFUs ($16M for MIFUS) • bNIRES ($11M, smallest and cheapest of all the instruments, very simple to commission, D**4 advantage). If secure outside funding for PFI, might consider both of the following: TMT.IAO.PRE.06.046.REL01

  16. NFIRAOS supports 3 instruments • NFIRAOS is a dual conjugate AO system • Order 61x61 DM and TTS at h=0 km • Order 75x75 DM at h=12 km • Better strehl and larger field than current AO systems (typically S < 0.37 in K band) IRIS Other NIRES • NGS WFS sensors are within IRIS • Completely integrated system • Fast (<5 min) switch between targets TMT.IAO.PRE.06.046.REL01

  17. NFIRAOS Widefield Performance LAOS simulations for 5 LGS TMT.IAO.PRE.06.046.REL01

  18. IRMOS-NFIRAOS • IRMOS-NFIRAOS (MCAO, not MOAO) • UF: 6 probes/spectros • $22M (SE, May 17, 2006) • $16M for simpler, non-upgradeable version (SE, Dec 5, 2006) • IRMOS studies demonstrated that there are lots of targets within 2’ • 6 probes/spectros selected for cost with still reasonable multiplex advantage TMT.IAO.PRE.06.046.REL01

  19. IRMOS-NFIRAOS • MOSFIRE - multislit NIR MOS • 45 slits • IRMOS studies demonstrated that there are lots of targets within 2’ TMT.IAO.PRE.06.046.REL01

  20. Instruments 5&6(Start in 2013; commission in 2021-2) Options: • HROS • UCSC version ~$25 - 40M (no contingency). CASA version $20M • Will HROS be competitive without LTAO? If not, add equivalent of MIRAO ($8M, no contingency). Could be added later (or wait for AM2) but what should the design be optimized for? • MIRES • Attractiveness is dependent on site and whether we have queue scheduling • ~$21M with MIRAO, no contingency • IRMOS-MOAO (= “IRMOS-SRD”) • MOAO concept still risky; no full demonstrator yet • ~$40-60M TMT.IAO.PRE.06.046.REL01

  21. New AO systems(2015-25) • AM2 studies will not be included in construction funds • Probably implies a later implementation of AM2 • Can make decisions later based upon improved knowledge of probable or actual telescope performance • Should have more knowledge about performance of other adaptive secondaries and of GLAO (LBT, VLT & Gemini) • DLIRAOS upgrade to NFIRAOS (to achieve 120nm wfe)? • As experience accumulates and as technology develops, a completely different approach is perhaps more likely than a direct upgrade to NFIRAOS (some sort of AO feed for IRMOS-SRD, for example) • Should plan for AO upgrades of at least $50M beginning in ~2015 • Implementation of a new capability every 3-5 years (AM2, DLIRAOS, IRMOS-SRD,…) • Supporting component development activities (detectors, DMs, MEMS, lasers, RTC processors…) TMT.IAO.PRE.06.046.REL01

  22. Needed from SAC • Priorities and Requirements for first light Instruments • IRIS, WFOS-July06 • Plan to start conceptual designs late in 2007 • Priorities for successive instruments • Data reduction SW requirements for instruments? • SAC subcommittees for each instrument? • 2-3 experts to engage in discussion? • Or continue “SAC liaisons”? TMT.IAO.PRE.06.046.REL01

  24. INST Oversight (Construction funds) • Overall manager for INST and AO starting in 2009 • Manager and Systems Engineer for INST starting in 2009 • Oversee contracts, develop interfaces, • Above three available to initiate future instrumentation activity • But that effort is outside the construction funding, included in development funding • More specialized engineers added to support I&T of IRIS and WFOS • Optical, mechanical, controls, SW • Instrument teams reassemble instruments at summit and participate in integration and commissioning • More details for this development activity are outlined in “Instrument Development Plan:Construction Budget” TMT.IAO.COR.06.006.REL01 TMT.IAO.PRE.06.046.REL01

  25. Instrument Development Office • Joint AO and INST engineering team that provides oversight for all instrumentation activities (except routine support) funded by both construction and operations funds. • Does not develop instruments in-house • Manages and provides systems engineering support (including commissioning) for AO systems and instruments • Initially primarily occupied with IRIS and WFOS and associated AO systems (CONS budget) • Increasing shift of effort towards support for future instruments and AO systems TMT.IAO.PRE.06.046.REL01

  26. IDO staff(preliminary - needs to be critically reviewed) • Led by an experienced astronomer/manager • Supported by AO and INST group leaders (engineers) and an overall instrumentation systems engineer • More specialists added as first light AO/instruments mature and as additional phases of instrument development begin • Optical • Mechanical • Controls • SW • AO • Laser • Based in North America • Initially co-located with project office • Most of activity involves interaction with instrument teams TMT.IAO.PRE.06.046.REL01

  27. INS FTE Profiles The instrumentation team builds up during the construction phase and then becomes the Instrumentation Development Office. The latter, and a small amount of activity to initiate future instruments before 2016, is funded by an on-going development budget TMT.IAO.PRE.06.046.REL01
