  3. SRT DESIGN GOALS • Large Diameter: 64 meters • Multiple Feeds • 300MHz to 100GHz • Receive and Transmit • Versatile Configuration – Can be used for: • Radio Astronomy • VLBI • Deep Space Probes (such as Cassini) • Use State-of-the-Art Technology • Minimum Technical Risks • Can be implemented in two stages: • Stage 1: Up to 22GHz  HOMOLOGY • Stage 2: Up to 100GHz  ACTIVE SURFACE

  4. SRT SCIENTIFIC MOTIVATIONS CONTINUUM RADIATION • Continuum Sky Mapping • VLBI • Improved Sensitivity • Space VLBI • Variability • Cosmic Microwave Background • Small-Scale fluctuations • Sunyaev-Zeldovich Effect • Galactic Background Polarization • Pulsars • Searches and Discovery • Fundamental Physics, Neutron Stars • Interstellar Medium studies • Support for Space Mission • Radio Stars • Flare Stars, RS CVn, Algol, X-ray, Novae • Solar System • The Sun • Planetary Radar • Spacecraft Tracking

  5. SRT SCIENTIFIC MOTIVATIONS SPECTROSCOPY • Extragalactic CO Studies • Evolution of Galaxies • Structure of Individual Galaxies • Extragalactic Molecules (other) • Normal Emission and Absorption • Masers • Galactic Studies • The Stellar Disk • Evolved Stars • Methanol • Diffuse Clouds • Dark Clouds Astrochemistry • Isotopes of Cosmological Interest • Solar System • Comets (OH, H2CO, HC3N, Urea) • HI: Extragalactic • Large-Scale distribution of Galaxies • Low-Luminosity Galaxies • High-Redshift HI Absorption • HI in Galaxies and Clusters • HI: Galactic • The Magellanic Stream Gas • High-Velocity Gas • Halo Gas • The Galactic Center • The Disk of the Galaxy • High-Latitude HI Mapping • Magnetic Fields via the Zeeman Effect
