summary
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
