Degree Angular Scale Interferometer

The Degree Angular Scale Interferometer (DASI) is a telescope located in Antarctica. It is a 13-element interferometer operating between 26 and 36 GHz in ten bands. The instrument is similar in design to the Cosmic Background Imager and the Very Small Array. DASI's aim is to study the Cosmic Microwave Background anisotropies and polarization. In 2002 the DASI team reported discovery of the CMB polarization.
