LiteBIRD是JAXA领导的大型战略卫星使命，旨在测量2020年代后期L2整个天空中34至448 GHz的宇宙微波背景和宇宙前景的偏振。该使命的主要重点是在大角度尺度上测量原始产生的B模式偏振。除了其主要的科学目标之外，LiteBIRD还将生成一个能够探测包括中微子质量总和在内的许多科学问题的数据集。美国的主要责任是为使命制造三个飞行模型焦平面部件。这些焦平面单元的设计和制造是由来自地面实验的遗产驱动的，并且将包括小透镜耦合的正弦天线像素和喇叭耦合的正交模换能器像素。该实验将有三个光学望远镜，称为低频望远镜，中频望远镜和高频望远镜，每个望远镜都覆盖了使命的一部分频率范围。日本宇宙航空研究开发机构负责建造低频望远镜，欧洲联盟负责建造中高频望远镜。由于空间环境的原因，频率覆盖范围广，光负载低，因此需要开发和改造最近由其他宇宙微波背景实验采用的探测器技术。这种设计、制造和表征将在加州大学伯克利分校、NIST、斯坦福大学和科罗拉多大学博尔德分校进行。我们向LiteBIRD使命介绍了美国可交付成果的当前状态。
LiteBIRD is a JAXA-led strategic Large-Class satellite mission designed to measure the polarization of the cosmic microwave background and cosmic foregrounds from 34 to 448 GHz across the entire sky from L2 in the late 2020's. The primary focus of the mission is to measure primordially generated B-mode polarization at large angular scales. Beyond its primary scientific objective LiteBIRD will generate a data-set capable of probing a number of scientific inquiries including the sum of neutrino masses. The primary responsibility of United States will be to fabricate the three flight model focal plane units for the mission. The design and fabrication of these focal plane units is driven by heritage from ground based experiments and will include both lenslet-coupled sinuous antenna pixels and horn-coupled orthomode transducer pixels. The experiment will have three optical telescopes called the low frequency telescope, mid frequency telescope, and high frequency telescope each of which covers a portion of the mission's frequency range. JAXA is responsible for the construction of the low frequency telescope and the European Consortium is responsible for the mid- and high- frequency telescopes. The broad frequency coverage and low optical loading conditions, made possible by the space environment, require development and adaptation of detector technology recently deployed by other cosmic microwave background experiments. This design, fabrication, and characterization will take place at UC Berkeley, NIST, Stanford, and Colorado University, Boulder. We present the current status of the US deliverables to the LiteBIRD mission.
