New developments within the TMT Quality Assurance program include the acquisition of an advanced metrology system to measure to very high precision the telescope primary mirror assemblies.
Pasadena, CA (June 06, 2019) – A Segment Support Assembly (SSA) “pre-build” meeting at the Coimbatore facility of Larsen & Toubro (L&T) was successfully completed on May 22, 2019. The meeting was aimed at assessing the readiness of the L&T team to start manufacturing their first SSAs. Participants included India TMT Coordination Centre (ITCC) and the TMT Project Office team.
The India TMT Optical Fabrication Facility (ITOFF), being constructed at the Indian Institute of Astrophysics campus in Hosakote, near Bengaluru, is rapidly approaching completion. The world-class optical facility was built by India-TMT as part of its contribution to the TMT partnership.
Pasadena, CA – February 6, 2019 – The Indian Institute of Astrophysics (IIA), on behalf of India TMT, recently signed a contract with Larsen & Toubro (L&T) to manufacture 100 Segment Support Assemblies (SSA) for the TMT. L&T is one of the largest leading construction engineering companies in India.
Pasadena, CA - Sept. 25, 2018 – The TMT Project Office recently held a conceptual design review to evaluate the design study for the TMT’s Adaptive Secondary Mirror (AM2) system.
PASADENA (July 26-27, 2018)– The Thirty Meter Telescope Optics Group recently achieved a critical milestone by passing its Primary Mirror Optics System (M1S) final design review. The review board, comprised of international reviewers and observers from various institutions including ESO, ITCC, JPL, JWST/Ball Aerospace, KECK, NAOJ, NIAOT, and the TMTPO*, met at TMT headquarters in Pasadena.
PASADENA July 11, 2018 – The conceptual design of TMT’s Cryogenic Cooling System (CRYO) has passed its conceptual design review. Engineers from the Technical Institute of Physics and Chemistry (TIPC) of the Chinese Academy of Sciences (CAS) joined TIO engineers at the project office to present the system that will be used to maintain parts of TMT’s first-light science instruments at cryogenic temperatures of 77 K.
On July 16, 2018, a workshop about TMT's Mid-Infrared Camera, High-disperser, and Integral field spectrograph (MICHI) was held at the National Astronomical Observatories, CAS (NAOC), Beijing.
Pasadena, March 16, 2018 - The conceptual design and scope of TMT’s Refrigerant Cooling System (REFR), which was executed and developed by a close Chinese-North American collaboration, successfully passed a recent conceptual design review. This system will be used to provide cooling to electronics enclosures mounted on the telescope structure. The system also maintains several TMT instrument enclosures at subzero temperatures to reduce thermal...
The shipment of TMT’s first meniscus-shaped primary mirror segment to the Indian Institute of Astrophysics (IIA) in Bengaluru (Bangalore) has just been completed.
The Real-Time Controller of TMT’s Narrow Field InfraRed Adaptive Optics System (NFIRAOS) successfully passed its final design review and is ready to proceed to the fabrication phase, which is expected to last approximately four years.
Following a successful second IRIS Preliminary Design Phase Review (PDR-2) at the TMT Project Office in Pasadena, IRIS is proceeding into its Final Design phase. The focus of the second review, held in September, involved an assessment of the IRIS software (including its data reduction system) and electrical design (including its detectors) as well as programmatic aspects spanning project cost and overall schedule.
Marking a major production milestone, TMT has entered into a contract with Coherent Inc., one of the world’s leading providers of lasers and laser-based technology for scientific, commercial and industrial customers, to polish its U.S. manufactured primary mirrors (M1) segments.
