| 研究実績の概要 |
Most of the past year research has been devoted to the design of new TES bolometers for the low frequency end of the spectrum for CMB observations (<100 GHz). The first iteration of fabrication is now ongoing and a first batch of detectors is expected for early JFY 2024.
In parallel I have focused on implementing various tools for science forecasting that take into account systematic effects and to attempt to mitigate them with several collaborators. A handful of papers have been written (or are in an advanced state) on various topics related to detector non-linearity, HWP non-idealities, detector gain, detector cross-talk, correlated noise and more.

現在までの達成度 (区分)
1: 当初の計画以上に進展している
理由
The research project has been moving ahead rather smoothly and while the pandemic disrupted some activities at the beginning. The impossibility of spending much of the fundings at the beginning has allowed us to focus on different details and freed more resources that can be used in this coming year to boost international collaboration.
|
| 今後の研究の推進方策 |
In the coming year I plan to focus on characterizing the detectors that are being fabricated and implement changes to the design for future fabrication iterations. In parallel I want to develop scaled model of some of the critical RF components to test them thoroughly and study possible solutions for improvement.
I will also continue pushing the development of new computational tools for science forecasting, data analysis and systematic effect mitigation.

| 次年度使用額が生じた理由 |
Most of the remaining budget is going to be used to foster international collaboration.
