Interferometer in Equatorial Mount at Dome C • Fork mount for Dome C since 75° latitude and excursions limited to ± 30° • Open frame tower, open structure and open telescope
Accessing Free Atmosphere Seeing 0.3" ➥ Open Frame 30 m Tower • Open frame towers' designs have been studied for the facility at Dome C (30 m tower), double height of DOT tower (15 m), to overcome TGL • Open dome and open telescope • Slow wind on tower (3-6 m/s) is a priori sufficient for mirror and telescope seeing control • Free platform/telescope 10xØ8 m 3 (winter-summer change/maintenance) • Tower stiffness is excellent (double structure: hexagonal hearth), 0.2" @ 7 Hz, and could be further improved by damping and frequency control ("elastics" between booms and bars to shift frequency like on DOT; or DVA to achieve better than 0.1")
