Thirty Meter Telescope

Astronomy's next generation observatory.


Foundation Documents

TMT has created a number of foundation documents to guide the design and implementation process. All of these documents are reviewed, revised, and reissued as necessary within a structured configuration control process.

The Detailed Science Case (pdf)

The Detailed Science Case (DSC) is the highest level statement of the TMT science case. The DSC was developed by members of the TMT International Science Development Teams and an editing team composed of members from all TMT partners. The DSC provides examples of the kinds of exciting, groundbreaking science that will be enabled by a 30m telescope. Wherever possible, synergies with other major new and upcoming facilities (e.g., the James Webb Space Telescope, the LSST and the Atacama Large Millimeter Array) are discussed. As appropriate, performance numbers (often conservative) are provided (e.g., sensitivities, integration times, spatial resolutions).

The Science-based Requirements Document (pdf)

The Science-based Requirements Document (SRD) describes the science-driven requirements for the Thirty Meter Telescope (TMT) project. TMT will be the first of the next-generation giant optical/infrared ground-based telescopes and will be a flagship facility for addressing the most compelling areas in astrophysics: the nature of Dark Matter and Dark Energy, the assembly of galaxies, the growth of structure in the Universe, the physical processes involved in star and planet formation and the characterization of extra-solar planets.

The Observatory Requirements Document (pdf)

The Observatory Requirements Document (ORD) contains the highest level system requirements for the observatory. Top level requirements are defined for the telescope and instrumentation, summit and support facilities, environmental health and safety, and high level software. The ORD also defines site specific environmental parameters and constraints.

The Observatory Architecture Document (pdf)

The Observatory Architecture Document (OAD) defines the high-level design for the observatory, including system wide implementation details, and the subsystem decomposition. It partitions function and performance requirements among the subsystems, as necessary, to ensure the integrated systems level performance of the observatory.

The Operations Requirement Document (pdf)

The Operations Requirement Document (OPSRD) contains high-level site-independent operations concepts and requirements science and technical operations. Science operations concepts are grouped into a minimum cost baseline service model and a more expensive enhanced service model. It is expected that each major TMT sub-system will have a separate operation concept document that describes operations, calibration, and maintenance processes.

TMT Construction Proposal (pdf)

In May 2007, an initial TMT Construction Proposal was created by the project and reviewed by an external advisory panel (EAP). The EAP membership is nominated by the TMT Board. This Construction Proposal will be revised and updated as TMT design and development proceeds.
