Cosmic Background Imager, Radio interferometer at Llano de Chajnantor Observatory, Chile
The Cosmic Background Imager consists of 13 antennas operating at frequencies between 26 and 36 GHz across ten bands at 5,080 meters elevation point.
The instrument started operations in 1999 and continued until 2008, measuring cosmic microwave background radiation with resolution exceeding one-tenth of a degree.
The California Institute of Technology constructed this instrument using radio amplifiers from the National Radio Astronomy Observatory, fostering international scientific partnerships.
The observatory location in the Chilean Andes offers minimal atmospheric interference and enhanced conditions for microwave observations through its high altitude position.
The telescope detected the first detailed E-mode polarization spectrum and found variations from expected patterns in high-l multipoles measurements.
