TMT Science and Instrumentation Workshop

• Start preparing for the OCDD (Operational Concept Definition Document).
• MOSFIRE will be shipped to Hawaii around 4/9/2011. FL is targeted around June.
• About modification or redesign from MOSFIRE to IRMS. ″Near″ clone of MOSFIRE.
• Study has started since 2007.
• Interface to the instrument rotator.
• Buffle thermal redesign.
• Configuration of the guider probe near focal plane.
• Thermal treatment of the window.
• Focal plane distortion.
• Scalloping effect?
• Flexure correction system with the instrument hanging downward.
• Flexure control of the grism turret. (Grisms are heavy.)
• Slit transmission.
• Investigate the curvature of the focal plane and slit position.
• Bibration measurement. (CTI 150 single-stage is used in MOSFIRE).
• Nick Konidaris will work on the optical redesign.
• Procurement of window material. CaF2? 1640?
• Need lamp for wavelength calibration? K-band.
• Noise trade off with what? (I can't be heard.)
• Performance at the four corners of 2′ x 2′ FOV.
• Narrow-band filter (in J-band) study by Betsy Barton?
• Modification for IRMS (by Luc, excerpt)

Tokoku: ″InfraRed Multi-Slit Spectrometer (IRMS): Technical Requirement Study″

TMT Science Performance Meeting
Matthias Schoeck +15 people.

• Measure for the NSF proposal.
• The Decadal Survey -> TMT science case mapping.
• AO simulation update.
• Not only comparing with Keck or Gemini, be focused on the TMT's distinctive capabilities.
• Detailed discussion on the observing method (calibration etc...).

2/28/2011 at TMT
TMT Astrometry Workshop
Jessica Lu, Andrea Ghez, Jerry Nelson +30 people.

• Science with the astrometric accuracy of 1 μarcsec.
• Ryuji's memo .

2/8/2011 at TMT
AO Modeling Meeting
Brent Ellerbroek +10 people.

• Met NFIRAOS group people.
• Can't catch up with the abbreviations for NFIRAOS...
• Simulation for wide-field mode in case of 20 and 50 % of seeing are not yet done.
  # At Mauna Kea, 25% and 50 % of seeing means roughly 0.7″ and 0.9″, respectively.
• Luc Gilles is working on the simulations.
• NFIRAOS team want to know IRMS's policy about the OIWFS, fore-optics design,
  required astrometry, and many other things. We have to work together.

2/3-4/2011 at Victoria (via videoconference from UCR)
NFIRAOS Interim Review

• Agenda
• Previous review was held on June 2010.

1/26/2011 at Caltech
MOSFIRE visit
Nick Konidaris, Ryuji Suzuki

• Just after 9th cryogenic test. The dewar was opened.
• CSU under repair by the SCEM engineers.
• Pinhole mask was used in the test.
• Optical performance under cryo-environment goes as designed.
• Detector noise. Striped pattern but uncountable.
• Next thermal cycle will be a final.
• Will be shiped to Hawaii by the end of the year.
• CSEM people feel like trying to make another CSU for IRMS.
• Pictures.
