  • The Degree Angular Scale Interferometer (DASI) was a telescope installed at the U.S. National Science Foundation's Amundsen–Scott South Pole Station in Antarctica. It was a 13-element interferometer operating between 26 and 36 GHz (Ka band) in ten bands. The instrument is similar in design to the Cosmic Background Imager (CBI) and the Very Small Array (VSA). In 2001 The DASI team announced the most detailed measurements of the temperature, or power spectrum of the Cosmic microwave background (CMB). These results contained the first detection of the 2nd and 3rd acoustic peaks in the CMB, which were important evidence for inflation theory. This announcement was done in conjunction with the BOOMERanG and MAXIMA experiment. In 2002 the team reported the first detection of polarization anisotropies in the CMB. In 2005, the vacant DASI mount was used for the QUaD experiment, which was another CMB imager focussed on the E-mode spectrum.In 2010, the DASI mount was again repurposed for the Keck Array, which also measures CMB polarization anisotropy.

  • Degree Angular Scale Interferometer (DASI) ialah sebuah teleskop yang dipasang di milik A.S. di Antartika. Teleskop ini merupakan sebuah interferometer dengan 13 elemen yang beroperasi di frekuensi antara 26 and 36 GHz dengan sepuluh frekuensi. Instrumen ini mirip rancangannya dengan (CBI) dan (VSA).Pada tahun 2001 team DASI mengumumkan pengukuran temperatur paling rinci, atau spektrum tenaga dari (CMB). Hasil ini berisikan deteksi pertama dari kedua dan ketiga dalam CMB, yang merupakan bukti kuat dari teori inflasi. Pengumuman ini dilakukan bersama dengan dan eksperimen . Pada tahun 2002 tim ini melaporkan deteksi pertama dari polarisasi anisotropi didalam CMB. Pada tahun 2005, dudukan DASI yang sudah kosong digunakan untuk eksperimen , yang merupakan pengindra CMB lainnya dengan fokus spektrum E-mode.Pada Tahun 2010, dudukan DASI ini kembali digunakan ulang untuk menaruh ,yang juga bertugas untuk mengukur anisotropi CMB.

  • Il DASI (dall'inglese Degree Angular Scale Interferometer) è un telescopio situato in Antartide. È uno strumento composto da 13 interferometri operanti in 10 bande tra i 26 e i 36 GHz. Il design dello strumento è simile ad quello di altri due esperimenti il CBI (Cosmic Background Imager) e il VSA (Very Small Array). Lo scopo del DASI è di studiare le anisotropie di temperatura della Radiazione cosmica di fondo (CMB) e la sua polarizzazione. Nel 2002 il team del DASI effettuò la scoperta della polarizzazione della CMB. (it)
