Experimental validation of a CO2 refrigerant-based thermal control system for the Giant Magellan Telescope (GMT) primary mirror (M1) segments
The Giant Magellan Telescope (GMT) employs seven 8.4m diameter borosilicate primary mirror segments whose optical performance depends on maintaining them at thermal equilibrium with ambient air during operations to minimize local seeing effects and to prevent figure distortions caused by temperature gradients. To meet...
