摘要
在这项工作中，我们描述了为第二次飞行做准备而对 Spider 气球载望远镜进行的升级，目前计划于 2021 年 12 月进行。Spider 仪器经过优化，用于在度角尺度上搜寻宇宙微波背景中的原初 B 模偏振特征。在 2015 年的首次飞行中，Spider 在 95 和 150 GHz 绘制了约 10% 的天区。第二次南极飞行的载荷将包含三个新的 280 GHz 接收机，以及来自 Spider 首次飞行的三个翻新的 95 和 150 GHz 接收机。在这项工作中，我们讨论了这些新接收机的设计与表征，其采用了超过 1500 个馈源喇叭耦合的跃变边缘传感器。我们描述了探测器特性的飞行前实验室测量以及已完成接收机的光学性能。这些接收机将在 280 GHz 绘制广阔天区，提供关于偏振银河系尘埃发射的新信息，有助于将其与宇宙学信号分离。
