17 September 2012 Recent performance improvements for the Large Binocular Telescope primary mirror system
Author Affiliations +
Over the last several years the primary mirror cell systems for the Large Binocular Telescope have been upgraded to improve on-sky performance and observing efficiency. We describe improvements made to the support actuators and mirror positioning system and explain how those changes have led to better performance and contributed to increased reliability. Both systems have been substantially redesigned and remanufactured to allow the LBT primary mirror systems to meet extremely precise performance requirements over a very broad temperature range. We also discuss the mirror ventilation and thermal monitoring system and review its current status and potential upgrades to improve its performance.
