摘要

AMiBA', as a dual-polarization 86-102 GHz interferometer array, is designed to measure the power spectrum of fluctuations in the cosmic microwave background (CMB) radiation, and to detect the high-redshift clusters of galaxies via the Sunyaev-Zel'dovich Effect (SZE). The operation of AMiBA is about to begin after installation of the first two receivers and correlators onto the 6-meter diameter platform by the end of 2005. The initial setup of the array will consist of 7 antennas with 60 cm diameter reflectors in a hexagonal configuration, aiming at multipoles / ~ 3000. Signals from receivers are cross-correlated in analog lag correlators. The initial operation will focus on characterizing the systematics by observing various known objects on the sky. The expansion to 13 elements with larger dishes will commence once the 7-element array testing is completed.
