Outline of Research at the Start

本計画研究は、技術基盤として極低温技術を新たに取り入れることで、ニュートリノを放出しない二重ベータ(0νββ)崩壊探索の検出器の高感度化と暗黒物質探索の範囲拡大を図る。極低温下での温度上昇によるエネルギー測定を行う原理を利用した蛍光熱量計を開発し、0νββ崩壊のQ値領域でエネルギー分解能として20keV以下を実現する。標的材料として極低温下で超伝導状態になったアルミニウムなどを使用し、内部のクーパー対解離を検知することで、O(10eV)の低エネルギー信号測定を目指す。低温技術を利用して、強磁場超伝導共振空胴の開発を行い、通常よりも2桁以上高い共振空胴の増幅度(Q値)を実現する。

Outline of Final Research Achievements

We firstly realized CaF2 scintillating bolometer using a superconducting sensor (MMC) for signal readout from cryogenic temperatures (around 10 mK). We achieved an energy resolution of less than 0.5% at the energy of 4.3 MeV, where is the Q-value of 48Ca double beta decay, and a particle discrimination ability of 5.5σ between α- and β-ray events when position dependence is eliminated by analysis using sequential α decay events in the CaF2 crystal.
A high magnetic field (9T) environment was utilized and Q-values were measured for cavities manufactured using ultra-high purity copper/photonic assist technology and so on. The target Q-value of 1.0E+5 was achieved in the cavity using photonic-assist technology and high purity alumina crystals.
The development of a KID made of Al was successfully performed by measuring the quasiparticle number counting to be able to detect the target below 10eV signal.

Academic Significance and Societal Importance of the Research Achievements

CaF2蛍光熱量検出器のエネルギー分解能が4.3MeV付近において0.5%以下になることを実証できたことで、48Caのニュートリノレス二重ベータ崩壊事象探索においてバックグラウンドを無視できるレベルまで低減でき、高感度探索に道が拓けた。強磁場(9T)環境下で目標としたQ値1.0E+5以上の共振空胴の開発に成功し、高感度アクシオン探索実験への道を拓いた。研究期間内にアクシオン探索実験のエンジニアリングランにも成功し、当初を上回る成果を得た。10eV以下の信号を検出できる超伝導検出器(KID)の開発に成功し、B01,B02が実現した暗黒物質探索の探索範囲を低質量領域まで広げることを可能とした。
