The TMT Enclosure System is a dome structure housing the telescope. The three principal enclosure moving components are the rotating base, cap and shutter structures. Combined rotation of the rotating base and cap provides a range of required azimuth and zenith angles. The shutter is a rotating structure enabling opening and closing of the telescope aperture.

The TMT design utilizes a calotte-style enclosure, which minimizes the size and footprint of the facility, while allowing full movement of the telescope and optical systems.

Fabricated by TMT-Japan, MSIT recreates a subset – approximately 1/70th - of the TMT primary mirror cell, and the segments it carries accurately recreate the unique hexagonal forms of the seven segments that will exist in the telescope in the same positions. Mirror segments in TMT are of 82 types – each one very slightly different – arranged in six identical sectors. MSIT contains segments from sectors D and E of the primary mirror.
