Abstract

The Advanced Technology Solar Telescope (ATST) project plans to implement thermal control of the primary mirror using jet impingement of temperature controlled air on the backside of the meniscus mirror. This technique will be used to minimize temperature rise of the optical surface due to coating absorption, minimizing mirror seeing effects. The performance of this system has been evaluated using numerical modeling techniques and weather data recorded at the proposed observatory site. To aid in the design of the M1 thermal control system for the ATST, a prototype test bed was designed, fabricated and tested. This paper reviews the progress and results of this development program.
