摘要
SPIDER 是一种气球载仪器，旨在在银河系前景存在的条件下，以角度尺度绘制宇宙微波背景图。SPIDER 利用 2000 多个超导转变边缘传感器（TESs）在南极大陆上方的两次 NASA 长续航气球飞行中绘制了大面积的南天天空。在 2015 年 1 月的首次飞行中，SPIDER 在 95 GHz 和 150 GHz 频段进行观测，对原初引力波的 B 模式特征施加了约束。其 2022–2023 年的第二次飞行新增了 280 GHz 接收机，每个接收机使用由硅片叠层形成的馈源喇叭耦合到天空的 TES 阵列。这些接收机经过优化，可在大面积天空上产生偏振银河尘埃发射的深度图，为该领域提供具有持久价值的独特数据集。本文描述了 SPIDER 第二次飞行期间仪器的性能，重点关注 280 GHz 接收机的性能。内容包括飞行细节、浮空时的带内光学负载以及探测器噪声的早期分析。
