| Outline of Final Research Achievements |
I improved the performance of the telescope for the CMB experiment, "GroundBIRD", by RT-MLI which I invented. RT-MLI is a new-type IR filter which is cooled by a similar principle to conventional multi-layer insulation. I success to cool down the super-conducting detector at 0.20 K with the optical loading from a 300-K black body.
I also evaluated the performance of the telescope using a detector fabricated by SRON. I confirmed that GoundBIRD has enough performance to the original design. Now, GroundBIRD telescope is almost ready to start the observation in Spain.
