  3. Current Status & Activities • Observer since June 2007 • Collaborating Institution since Nov 2008 • Goal: Equal Partner (~25% Contribution) • NAOJ Budget in FY2010 (Apr~Mar): $1M for R&D (M1, M3, etc.) • 2010 June: Submitted R&D Budget for FY2011 (~$10M including M1, M2/M3, Instruments) • 2011 June: Submission of Construction Budget plan from FY2012 to 2020 (TBD: ~$350M including 1st & 2nd instruments) • Call for Proposal of TMT-J Instruments on June 2008 Four Instruments were selected and have been studied • Internal review meetings (Panels: F.Iwamuro, T.Kodama, N.Takato, T.Usuda) for Key technologies, Science cases, Budget, etc.)

  4. TMT-J Four Instruments High Priority & Feasibility • MICHI (Mid-IR Camera, High-disperser, and IFU) (Y.Okamoto+): Modified MIRES ← COMICS, TAO • NIR High Dispersion Spectrograph(N.Kobayashi+): NIRES-b and NIRES-r ← IRCS-HRU, WINERED & IRDI (Immersion Gr., Astro-Comb, fiber) Medium Priority & Feasibility • NIR Multi IFU spectrograph with MOAO (M.Akiyama+): IRMOS ← RAVEN, SIRMOS • Optical High Dispersion Spectrograph (W.Aoki+): HROS ← HDS, HIDES (I2 cell, image slicer, fiber)

  5. MICHI (Mid-IR Imager & Spectrometer) • Imaging & Spectroscopy @7~25um • FOV=27.5x27.5” / 0.”08@10um w/ MIRAO • IFU (R=300@N / 600@Q), Long-slit (900 / 1800), Echelle (120,000 / 60,000) • Options: Polarimetry @N-band • Key sciences • Planet formation & Biomarkers • Material lifecycle in the universe • AGN & Cosmology • Collaborations w/ UH & Florida team (Tokunaga/Chun/Packham) • R&Ds • Image slicer etc. MIR slicer

  6. NIR High Dispersion Spectrograph • R=40,000 (80,000 max) • Short arm (0.9~2.5um) & Long arm (1.9~5.5um) • Slit: 0.”02 x 0.5~1” • Options: Long slit (15~30”) / MOS (5~10 targets) • J~20, H~20, K~19.5(10σ) R~50,000, 1hr • Key sciences • IGM at 2.5<z<6(metallicity), and z>6 (re-ionization) • Atmosphere of exoplanets • Collaborations with UH NIRES team (J.Rayner/A.Tokunaga) • Prototype: WINERED, IRCS-HDU, & IRDI • ZnSe & Si immersion gratings • Molecular gas cell, Laser comb.

  7. NIR Multi IFU spectrograph w/ MOAO • NIR IFU spectroscopy of 10~20 objects simultaneously (cf. IRMOS) • FOV 5arcmin w/MOAO, spatial resolution 0.”02@2um • 20 IFU units, R=1,000~20,000 • Key sciences • Search for galaxies in formation-phase at 7<z • Physical properties of galaxies in growing-phase at 2<z<7 • Collaborations w/ U.Victoria, HIA for RAVEN on Subaru Telescope • R&Ds • Large stroke (>20um) MEMS-DM • tomography algorithm • Fiber IFU • …

  8. Optical High Dispersion Spectrograph • “Ulitimate” Optical Spectrograph focusing on the accuracy and stability (e.g., CODEX, ESPRESSO) • Key sciences • Detection of terrestrial exoplanets around solar-type stars • Direct measurement of cosmic expansion • Required accuracy of radial velocity ~10 cm/s (e.g. 1m/s accuracy is attained with current ESO HARPS) • R&Ds • Stabilities of inst. Temperature, air pressure, opt. alignment • Laser comb • Image Slicer

  9. Current Activities: Instrumentation • Schedule (TBD due to budgetary condition and negotiation): • 2010 Summer: Submission concept design to TMT-J project • 2010 Fall: First two J-instruments selection • 2010 Dec: Submission two proposals to TMT • 2012: TMT Design Review process (see table) • 2019: Commissioning on site and test observations

  10. Summary • Various activities to make a concrete business plan including the telescope optics (M1/M2/M3), instruments, etc. • Four 2nd generation instruments have been proposed. • We would like to submit the Construction Budget plan from FY2012 to 2020 (TBD: ~$350M) on June 2011 →Need agreements and negotiation with TMT & partners • Activate TMT science symposium and science cases → Invitation of TMT SAC & partner members for such meetings in Japan
