TMT’s main cooling units REFR-A, REFR-S and REFR-H are installed at ground level in the summit observatory utility room. The Refrigeration Cooling System (REFR) also provides all of the CO2 piping that supplies the hydrostatic bearing system heat exchanger, as well as the REFR-A and REFR-S client systems located on the telescope structure.
TMT’s APS includes all the necessary hardware, software, and interfaces to the Telescope Control System and M1, M2, and M3 control systems required to accomplish precise alignment of all TMT’s mirrors. The APS will have the capability to phase the 492 M1 segments so they behave as one unique single mirror of 30 meters in diameter.

Stylized view of the Thirty Meter Telescope with the telescope tube structure suppressed to highlight instruments and the segment handling system. On the far side of the segmented primary mirror is the adaptive optics enclosure in blue that supports the MODHIS First Light instrument on top (also in blue, inside the safety rails). The charcoal colored structure immediately to the left of the adaptive optics system is the telescope optics Alignment and Phasing System (APS). The tertiary mirror in the center of the primary mirror is oriented to send light to the Wide Field Optical Spectrograph, the light gray structure located on the instrument platform on the right foreground of the image. At the rear right is the part of the mirror segment handling system that transfers segments up and down to the observatory floor and on and off the segment handling system above the primary mirror (not shown).

The Thirty Meter Telescope is shown at a very low elevation angle. The segmented primary mirror reflects the convex secondary mirror. The tertiary mirror in the center of the primary mirror is oriented to send light to the Wide Field Optical Spectrograph, the gray structure located on the right side of the image. The left and right instrument platforms are seen and the dark blue adaptive optics enclosure is seen on the upper left on the instrument support structure.

TMT Segment Support Assemblies (SSA) are opto-mechanical systems that provide the support for each individual piece of mirror segment. During transport and storage within their container, SSAs are entirely wrapped in a zipped closed Intercept fabric bag for protecting the delicate electronic features from moisture and corrosive environment. Data loggers are mounted into the container and on the SSA to monitor and collect information on shock amplitude, temperature and humidity.
