The frame members ended up being passively cooled by enclosing Simple man eagles guitar Lynyrd Skynyrd shirt in two concentric PVC pipes and adding little RC-servo controlled vents to ventilate the outer and/or inner space as needed (my contribution). It all worked in closed loop and stabilized the off-axis deflections of the frame to well under a micron. The non-straight frame elements were enclosed in custom styrofoam coolers, again passively vented. The mirror thermal stability was done with slowly circulating water – one from a well (cold), through a storage tank, another from a solar-heated hot storage tank. The mirror had 40 thermal control zones. A buddy of mine built a clever shape sensing system for the mirror that was completely based on mechanics of materials and did not need to use an interferometer for reference – although it was interferometer validated of course. Another gal was in charge of smart optics and IIRC made some contributions to the field while developing her solution, although she didn’t really work in the field very long. The main mirror stability was needed since one design goal was to have maximum performance possible even when the adaptive optics were off line.

After the “non-adaptive” optics saw first light and the sensor was all sorted out, Simple man eagles guitar Lynyrd Skynyrd shirt were totally out of power for the artificial star for adaptive optics, so that took some further savings in various subsystems. I had to learn how to design switching regulators, for one thing, and to rework the power supplies to use 48V and 96V instead of the original 24V that proved inefficient. Replacing the drive motors a scary experience – almost dried up the budget.
