Sharper Focus, Part 2 - How TMT’s Adaptive Optics Will Work
April 19th, 2018 Associate Project Manager Blog

In an earlier companion post (Sharper Focus, Part 1), I introduced the concept of adaptive optics and talked about some of the ways astronomers and engineers have used those techniques to sharpen the images we capture. Now I’d like to show you some of the specific adaptive optics solutions that will enhance TMT’s vision.

Sharper Focus -Part 1- The Why and How of Adaptive Optics
April 11th, 2018 Associate Project Manager Blog

The Atmospheric Lens TMT’s unprecedented ability to peer into the depths of the Universe means it will have a phenomenal impact on many areas of astronomy. But in this age of space-based telescopes, you may have wondered how a ground-based observatory like TMT (or some of the other next-generation large terrestrial telescopes) will get past the challenges of being on the ground instead of up in orbit. One of the major challenges is...

Thirty Meter Telescope’s Refrigeration Cooling System Passes Conceptual Design Review
March 19th, 2018 Engineering & Technology

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...

China's Contribution to TMT's Primary Mirror
February 22nd, 2018 Associate Project Manager Blog

Until recently, eyeglass lenses were actually made of glass-remember the "Coke-bottle-bottoms" some people had to wear? Given the fragility and other quirky qualities of glass, you can imagine the delicacy with which the optician had to grind every lens blank to achieve exactly the right specifications. Now picture 492 glass pieces - actually, mirror segments once they have the reflective coating added -each weighing as much as a dozen car...

Stressed Mirror Polishing
February 12th, 2018 Associate Project Manager Blog

“Wax on, wax off,” said Mr. Miyagi to "The Karate Kid" (1984), to help the kid develop efficiency of movement, attention to detail, and grace—while also polishing Mr. Miyagi’s classic car. What could this possibly have to do with TMT?

Segment Support Assembly Production in the USA
February 1st, 2018 Associate Project Manager Blog

As I’ve explained elsewhere in this blog, segment support assemblies are what hold in place each of TMT’s primary mirror segments. They also let each segment be positioned in real time to provide the best possible imaging capability. Staff at the TMT Project Lab in Monrovia, California, are building six segment support assemblies to determine whether the design can be manufactured in a repeatable, problem-free manner.
