Outline of Annual Research Achievements

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.
