| Outline of Final Research Achievements |
Simons Observatory is the project to observe cosmic microwave background (CMB) using four millimeter-wave telescopes. The telescopes have been built at the Atacama dessert (altitude of 5,200 m) in Chile. Japanese group is in charge of cryogenic optics tubes set in the telescope receivers. We succeeded in development them. The first telescope which is installed the optics tube is under commission towards "the first light" (starting observation) in 2023. Based on our design studies and laboratory test results, we obtained prospects to achieve the best sensitivity to date for detecting primordial gravitational waves from the cosmic inflation, and for measuring a sum of neutrino masses.
