Sardinia Radio Telescope
From Wikipedia, the free encyclopedia
The Sardinia Radio Telescope is a large, fully steerable radio telescope recently completed near San Basilio, province of Cagliari in Sardinia, Italy. It is a collaboration among the Istituto di Radioastronomia di Bologna, the Cagliari Observatory (Cagliari) and the Arcetri Astrophysical Observatory (Florence). It has been completed in 2011.
The main technical points are:
- A 64 meter primary mirror with a 7.9 meter secondary;
- A Gregorian configuration with shaped surfaces
- An active surface: Primary mirror adjustable with 1116 actuators;
- 0.3-115 GHz continuous frequency coverage
- Three main focal points: Primary, Gregorian, and Beam Wave Guide
- Primary surface accuracy: ≈150 μm RMS
- Maximum antenna efficiency: ≈60 %
- Pointing accuracy (RMS): 2-5 arcsec
