This cartoon model highlights the constraints, assumptions, and discussions related to the Instrument Development Office of the Thirty Meter Telescope project. It covers funding mandates, available finances, instrument development timeline, and the need for a coherent roadmap for construction proposals. The importance of flexibility and sensitivity to advancements in astrophysics and technology is emphasized, with a call for regular review and revision of the roadmap by the Scientific Advisory Committee.

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.OPS.PRE.06.011.DRF01

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.OPS.PRE.06.011.DRF01
