The Arcminute Cosmology Bolometer Array Receiver (ACBAR).

By K Romer, MC Runyan, RS Bhatia and AE Lange


We describe the Arcminute Cosmology Bolometer Array Receiver (ACBAR) which is a 16 pixel, 240mK multifrequency bolometer array for measuring primary and secondary anisotropies in the CMB at millimeter wavelengths. ACBAR observes from the 2m Viper telescope at the South Pole and has just concluded its second year of CMB mapping observations. In this talk we will discuss the instrument design and performance as well as preliminary results from a blind survey for massive clusters of galaxies using the SZ effect. ACBAR is funded by the Center for Astrophysical Research in Antarctica (CARA), an NSF Science and Technology Center
