摘要
BICEP3 是一台 520mm 孔径的同轴折射望远镜，在 95GHz 观测宇宙微波背景（CMB）的偏振，以搜寻源自暴胀引力波的 B 模信号。BICEP3 的焦平面由天线耦合的过渡边缘传感器（TES）辐射热计模块化瓦片构成。BICEP3 于 2014-15 年南极夏季部署至南极，并自此运行。在 2016-17 年南极夏季，我们对光学元件进行了改动，从而带来更好的噪声性能。我们讨论此次升级，并展示 BICEP3 在 2017 和 2018 观测季以全绘图速度下的性能。与 Keck 95GHz 接收机相比，BICEP3 的绘图速度实现了数量级提升。我们展示了 BICEP3 接收机 的噪声性能。
