The production of TMT鈥檚 primary mirrors in North America is progressing very well. Several polished glass-ceramic roundels are currently in production at the Coherent manufacturing facilities; three were recently finished and shipped to the TMT storage facility in the Bay Area.
The TMT Laser Guide Star Facility (LGSF) has successfully completed the first phase of its Preliminary Design Review (PDR1). The LGSF will be responsible for generating artificial laser guide stars that will be used with TMT鈥檚 Adaptive Optics (AO) systems, including NFIRAOS, the Observatory鈥檚 first-light AO facility.
The optical metrology and test set for TMT鈥檚 primary mirror segments has arrived at its warehouse in California. It was sent by Arizona Optical Systems (AOS) in Tucson, Arizona, on May 11 and arrived safely the day after at the TMT storage facility after a 500-mile journey. All fabrication and test tooling for the complete metrology system were also included in the freight.
The handling equipment for TMT primary mirror (M1) segment recently passed its Preliminary Design Review. The custom-designed equipment and tooling will be used to safely handle mirrors within the observatory during operational activities.
TMT is deeply saddened by the passing of TMT Systems Engineer Hugh Thompson on May 7, 2021. Hugh was a colleague, good friend and inspiration to many of us who were fortunate to interact with him over his career.
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.
TMT鈥檚 Science Advisory Committee (SAC), which has been meeting bi-monthly since the start of the Covid-19 pandemic, recently met to address the project status, its scientific potential and suitable instrumentation. The SAC is composed of representatives from each TMT partner who advise the Project on TMT鈥檚 design, strategies and operational matter that can have a significant impact on TMT science.
TMT and Coherent reached a new milestone this month with the completion of the first two roundels for TMT鈥檚 Primary Mirror (M1). Coherent precisely contoured and polished the optical surfaces of the roundels under the direction of TIO. They are the first of 231 roundels Coherent will provide for the TMT primary mirror array, nearly half of the total of 492 required to complete the telescope.
