Abstract

The Advanced Atacama Cosmology Telescope Polarimeter (AdvACT) is an upgraded instrument for the Atacama Cosmology Telescope, which uses transition-edge sensor (TES) detector arrays to measure cosmic microwave background (CMB) polarization anisotropies in multiple frequency bands. We review the integration and characterization of the final polarimeter array, which is the low frequency (LF) array, consisting of 292 TES bolometers observing in two bands centered at 27 GHz and 39 GHz. This array is sensitive to synchrotron radiation from our galaxy as well as to the CMB, and complements the AdvACT arrays operating at 90, 150 and 230 GHz to provide robust detection and removal of foreground contamination. We present detector parameters for the LF array measured in the lab, including saturation powers, critical temperatures, thermal conductivities, time constants and optical efficiencies, and their uniformity across the entire wafer.
