论文摘要

对宇宙微波背景的观察依赖于带有冷探测器，读数和光学的低温仪器，提供了低噪声性能和仪器稳定性，以进行更敏感的测量。因此，至关重要的是，优化低温设计的所有方面，以低温组件和可接受的系统冷却要求，以实现必要的性能。特别是，我们将专注于使用热过滤器和冷光学元件，从而减少了传递到低温阶段的热载荷。为了测试他们的性能，我们进行了一系列原位测量，同时集成了二头肌阵列望远镜的第三个接收器。除了表征该接收器的行为外，这些测量值还继续完善用于为未来仪器做出设计选择的模型。

Observations of the Cosmic Microwave Background rely on cryogenic instrumentation with cold detectors, readout, and optics providing the low noise performance and instrumental stability required to make more sensitive measurements. It is therefore critical to optimize all aspects of the cryogenic design to achieve the necessary performance, with low temperature components and acceptable system cooling requirements. In particular, we will focus on our use of thermal filters and cold optics, which reduce the thermal load passed along to the cryogenic stages. To test their performance, we have made a series of in situ measurements while integrating the third receiver for the BICEP Array telescope. In addition to characterizing the behavior of this receiver, these measurements continue to refine the models that are being used to inform design choices being made for future instruments.
