TMT’s telescope structure subsystem (STR) recently completed two successful Production Readiness Reviews (PRR2 and PRR3) to assess the availability of adequate resources and planning for production, and later for assembly, integration and verification. The STR’s design and future fabrication are activities led by NAOJ and their prime contractor...
The teams working on TMT’s Segment Handling System (SHS) and utility system design received some good news following a series of critical review meetings earlier this spring. The TMT Telescope Structure Subsystem (STR) and Summit Facility (SUM) groups conducted the reviews and based on the outcome, the teams mays now proceed independently with the final design of their systems toward production preparation.
TMT’s Wide-Field Optical Spectrometer (WFOS), one of its three first-light instruments, successfully completed its Conceptual Design Review in February 2022. This review completed the conceptual design phase and ushered WFOS into its Preliminary Design Phase.
A virtual meeting was conducted on April 5, 2021 between representatives of the National Astronomical Observatory of Japan (NAOJ, TMT Japanese Partner Institution) and the TMT Project Office (TMTPO) Telescope Structure Subsystem (STR), Systems Engineering (SE) and Project Management (PM) teams. The goal of this closeout meeting was to verify closure of all major actions from the STR Production Readiness Review (PRR) 1 which was conducted...
TIO recently celebrated the completion of another eight newly polished roundels produced for the TMT primary mirror by Canon in Japan. The TIO and NAOJ teams responsible for the mirror polishing held a face-to-face meeting virtually on April 27, 2021 to confirm that the polishing results met the demanding requirements for these parts.
The Thirty Meter Telescope Optics Group recently reached a critical production milestone, with the approval of the first polished roundel (# SN023) for TMT’s Primary Mirror (M1). Teams at TIO, NAOJ, and Canon reviewed the manufacturing operations required to turn a meniscus mirror blank into a polished roundel, and the roundel was confirmed to meet all requirements set by the TMT Project. This approval obtained in December 2020 validates years...
As an extremely complex organization of systems all interacting together, TMT will require an elaborate Telescope Utility Services (TUS) infrastructure to enable operations within the observatory, across the summit facilities, enclosure, and telescope. The first tier of TMT’s TUS successfully passed its Final Design review, covering elements of the design that pertain to the Telescope Structure and its various interfaces, via video...
TMT Optics and Systems Engineering teams recently conducted a technical evaluation of the primary mirror optical cleaning system, marking a major milestone in its design. The Optics Cleaning System (CLN) for TMT’s segmented primary mirror (M1) as well as the secondary (M2) and tertiary (M3) mirrors successfully passed Preliminary Design Review (PDR) on August 19 and 20, 2020 during a remote conference meeting.
Scientists recently attended the first joint TMT-GMT Science Advisory Committee (SAC) meeting. Due to the COVID-19 pandemic, the meeting was held virtually to ensure the safety of all its members. The meeting was of historical importance, as it was the first of its kind to be commonly organized with the Giant Magellan Telescope (GMT) Science Advisory Committee.
Coherent Inc., one of the world’s leading providers of lasers and laser-based technology, is now ready to polish all of the TMT primary mirrors segments to be manufactured in the United States.
