摘要
CMB-S4——下一代地基宇宙微波背景（CMB）实验——将显著提升 CMB 测量的灵敏度，并增进我们对宇宙起源与演化的理解，从创世之初的最高能量，到结构的生长，直至今天。在 CMB-S4 所追求的科学目标中，探测原初引力波是实验设计的核心驱动力。本工作详述了一个预报框架的开发，该框架包含一个基于功率谱的半解析投影工具，明确针对在银河系前景和 CMB 引力透镜存在的情况下优化对张标比 的约束。该框架的独特之处在于直接利用当前第 2—3 阶段 CMB 实验已实现的性能信息，以稳健地预报未来 CMB 偏振探测的科学可达范围。该方法允许对实验配置进行快速迭代，并提供了一种灵活的方式，在给定期望科学目标的情况下优化未来实验的设计。为形成闭环过程，我们将此半解析工具与基于图的验证研究相结合，从而能够引入额外的复杂性，并用若干独立的分析方法验证我们的预报。我们记录了使用此过程对 CMB-S4 进行的多轮预报，以及由此确立的第四阶段实验原初引力波分量的当前参考设计，其优化目标为以大于 的置信度探测 的原初引力波，或在未探测到的情况下，以 CL 达到 的上限。
