2005 Near Term Instrument Development Timeline Proposals submitted to Gemini and reviewed by Source Selection Board (SSB) SSB scored proposals and recommended which teams should be funded to carry forward studies for the ExAOC, HRNIRS, WFMOS, and GLAO In the process of putting 8 teams under contract Including one led by AAO to do now GWFMOS feasibility study 2003 2004 2005 Near Term Instrument Development Timeline All design and feasibility studies due end of January 2005

Design studies will be reviewed by expert panels that will recommend a down-select to a single team to go forward with ExAOC and HRNIRS Feasibility studies will be reviewed though no competitive down-select process required Entire process enters a built in hold state to assess options and determine which, if any, of the instruments should be pursued via follow-on contracts 2003 2004 2005 High Resolution NIR Spectrometer Design Requirements Single-slit cross-dispersed mode 0.2 arcsec spatial sampling Slit length ~3 arcsec One-shot wavelength coverage as large as possible Spectral resolution R~70,000 Absorption cell for precision radial velocity measurements Multi-object MCAO-fed spectrometer Spatial sampling 0.05 arcsec
