摘要
时分复用是许多地面与空间实验首选的读出架构，因为它是一项非常成熟的技术，具有经证实的出色低频噪声稳定性，而这正是复用中的核心挑战。完全部署后，两台分别观测于 150GHz 和 220/270GHz 的 BICEP 阵列高频接收机每台将在焦平面上排布 7776 个 TES 探测器。这两台接收机的约束条件要求重新设计温端读出电子学。此处首次展示由不列颠哥伦比亚大学开发建造的标准多通道电子学（Multi Channel Electronics）的新版本。BICEP 阵列将时分复用读出技术在复用率、噪声与串扰方面推向能力极限，并将其应用于对噪声性能和系统误差控制有极严苛要求的严谨科学观测。未来如 CMB-S4 等实验计划使用带时分/SQUID 基读出的 TES 辐射热计，探测器数量将更为庞大。
