先进的阿塔卡马宇宙学望远镜偏振仪是阿塔卡马宇宙学望远镜的升级接收器，阿塔卡马宇宙学望远镜已经开始使用四个新的多色超导探测器阵列中的第一个来测量宇宙微波背景中的小角尺度极化各向异性。在这里，我们回顾了第一个阵列的优化和表征的所有细节，该阵列采用了工作在150 GHz和230 GHz的2012年AlMn过渡边缘传感器测辐射热计。我们给出了阵列的临界温度、热导率、饱和功率、时间常数和灵敏度。测试结果表明，150 mm硅片表面具有较高的均匀性和良好的现场应用性能。
The Advanced Atacama Cosmology Telescope Polarimeter is an upgraded receiver for the Atacama Cosmology Telescope, which has begun making measurements of the small angular scale polarization anisotropies in the Cosmic Microwave Background using the first of four new multichroic superconducting detector arrays. Here, we review all details of the optimization and characterization of this first array, which features 2012 AlMn transition- edge sensor bolometers operating at 150 and 230 GHz. We present critical temperatures, thermal conductivities, saturation powers, time constants, and sensitivities for the array. The results show high uniformity across the 150 mm wafer and good performance in the field.
