项目摘要

The instrument development for the Simons Observatory (SO) CMB experiment has continued throughout the 2019 fiscal year. The optics design of the small aperture telescopes (SATs), that Japan and USA will develop and deploy by 2021, has completed and fabrication of the first SAT is in-progress. We, along with the SO Japanese collaborators, have been fabricating the optics tube which contains the optical lenses of the SAT instrument. The first optics tube is near completion and will be integrated with the SAT receiver in the near future. The second and third optics tube fabrication has also started in Japan. The fabrication of the SAT platform and shields, that reduce stray light systematics, has also been proceeding.The SO Japanese collaborator meetings have also taken place regularly throughout the fiscal year. We have organized four quarterly face-to-face meetings within Japan in the 2019 fiscal year, and participated in a full (world-wide) collaboration meeting which took place in the USA. The SO Japanese collaborators have been regularly presenting and updating on the SO development progress at the bi-annual JPS and ASJ conferences in Japan.The planning for the next generation CMB-S4 experiment, which will start instrument development in the 2020s, has started. Some of the SO Japanese collaborators are also part of the CMB-S4 R&D team, and we have been working on the reference design concept of the next generation small aperture telescope array. A world-wide CMB-S4 collaboration meeting was also held in the 2019 fiscal year in the USA.

西蒙斯天文台（SO）CMB实验的仪器开发在整个2019财年持续进行。日本和美国将于2021年开发和部署的小孔径望远镜（SAT）的光学设计已经完成，第一个SAT的制造正在进行中。我们与SO日本合作者沿着一直在制造光学管，其中包含SAT仪器的光学透镜。第一个光学管已接近完成，将在不久的将来与卫星接收器结合。第二和第三个光学管的制造也已在日本开始。减少杂散光系统的SAT平台和防护罩的制造也在进行中，SO日本合作者会议也在整个财政年度定期举行。2019财年，我们在日本国内组织了四次季度面对面会议，并参加了在美国举行的全面（全球）合作会议。SO的日本合作者定期在日本举行的JPS和ASJ会议上介绍和更新SO的开发进展。计划于2020年代开始仪器开发的下一代CMB-S4实验已经启动。SO的一些日本合作者也是CMB-S4研发团队的一部分，我们一直在研究下一代小口径望远镜阵列的参考设计概念。2019财年还在美国举行了全球CMB-S4合作会议。
