Outline of Final Research Achievements

We have studied the methods to solve the four main challenges in realizing a TES-type microcalorimeter with 57Fe thin film as a solar-axion converter by elemental prototyping and electromagnetic field simulation. We then designed and fabricated a TES microcalorimeter based on the solutions, and evaluated it by X-ray irradiation. As a result, it was found that the waveform at the rising edge of the signal varied greatly, and the cause of this variation was investigated by simulating the thermal response of the detector. As a result, it was suggested that the thermal conductivity of the gold thin film was insufficient, and a fabrication method was developed to improve it. Based on these results, we designed an 8x8 format array element and prepared for signal readout by microwave frequency-space signal multiplexing.

Academic Significance and Societal Importance of the Research Achievements

TES型マイクロカロリメータアレイ検出器は優れたエネルギー分解能が特徴であり,宇宙X線観測に加えて,高エネルギー分解能で得られる低バックグラウンドを生かした稀事象探査への応用が特に期待される。本研究は稀事象探査の一つとして太陽アクシオン探査を目標とする。本研究により64画素の検出器を実現する基礎的な知見が得られた。本格的な探査には千以上の素子が必要である。信号読み出し回路を含めたシステム全体はスケーラブルであるので,時間と経費をかけることで実現の可能性は高い。また,今回研究した熱への変換物質をTESの横に配置する方式は応用性が高く,他の稀事象探査への応用も期待される。
