A major milestone for the international Thirty Meter Telescope project (TMT) was reached in October 2020, as TMT selected California-based Coherent, Inc. for the Hexagonal cutting of the US allocation of its Primary Mirror (M1) segments. Coherent is one of the world’s leading providers of photonic solutions, including lasers and custom optics,...
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 have reached another major milestone, with a successful “gate” review of the TMT optical Test INstruments System (TINS) preliminary design.
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.
One of TMT’s three “Early Light” instruments, the Wide-Field Optical Spectrometer (WFOS), recently underwent an interim Conceptual Design Review via Zoom. The review’s purpose was to assess the instrument’s progress to date and to provide guidance on potential work needed to successfully complete the technical and scientific aspects to bring the overall design to a full Conceptual Design level.
Recently, the TMT Engineering Sensors System (ESEN) successfully passed its Preliminary Design Review (PDR) and is now ready to enter the Final Design phase. Chris Carter and Scott Michaels, TMT telescope control and software engineers, led a team of four people in presenting the design to the review panel.
The Thirty Meter Telescope recently reached another critical development milestone with the successful Conceptual Design Review close-out meeting of the Cryogenic Cooling System (CRYO). The online review, held on May 19, 2020, focused on the completion of the recommendations that arose from the CRYO Conceptual Design Review held in August 2018.
The first TMT primary mirror (M1) metrology frame has been built and delivered to TMT’s technical laboratory near Pasadena. TMT will use the metrology frames, which are auxiliary equipment tools, to accurately locate the M1 mirror segments during installation.
TMT’s Enclosure System has achieved its final design milestone, successfully passing a series of Production Readiness Reviews (PRR) in March 2020.
