Outline of Annual Research Achievements

我々は次世代のMeVガンマ線望遠鏡として、電子飛跡検出型コンプトンカメラ(Electron Tracking Compton Camera, ETCC)の開発を進めている。ETCCは従来型コンプトンカメラと異なり反跳電子の飛跡を測定することで、優れた撮像性能に基づく強力な雑音除去性能と、6 strもの広視野を実現している。さらに昨年度までに、100-200 keVで約0.6と優れた偏光検出性能(Modulation Factor, MF)を持つことを、モンテカルロシミュレーションと密封線源を用いた室内実験の両方で確かめた。
本年度は、SPring-8の偏光X線ビームラインBL08Wを利用して高統計での精密測定を行なった。182 keV直線偏光ビームを10 mm厚のアルミ板に照射し、その散乱光をETCCで測定した。ETCCに対する入射光子の偏光方向を変えて測定を行い、そのいずれにおいても得られたエネルギースペクトル及び偏光検出に関わる散乱X線方位角分布は、シミュレーションとよく一致した。得られたMFは0.56-0.61@130 keVとシミュレーションと矛盾せず、既存のコンプトン偏光計より1.5倍程度優れた値であることが確認できた。さらに広視野撮像偏光観測の実証実験として、偏光X線を光軸から約40度傾けて入射させ、撮像情報により精度の高い偏光検出が行える事を示し、世界初のX線撮像偏光検出を成功させた。今後のETCCの有効面積拡張により、気球実験でもかに星雲や明るいガンマ線バースト等について10-20%偏光検出と、衛星観測に匹敵する高精度な観測が期待できる。
