抄録/ポイント： 要約。軌道内機器バックグラウンドの理解と低減は,硬X線天文観測において高感度を達成するために必須である。Hitom衛星搭載の硬X線イメージャ(HXI)の観測データは,異なる原子番号の多層構成によるバックグラウンド成分に関する有用な情報を提供し,HXIは,Si(Z=14)検出器の4層のスタックと,井戸型Bi_4Ge_3O_12活性遮蔽に囲まれたテルル化カドミウム(CdTe)(Z=48,52)検出器の1層から成る。観察データに基づいて,上部Si層のバックグラウンド,三つの下層Si層,およびCdTe層は,それぞれ,低エネルギー電子,アルベド中性子,およびプロトン誘起放射線活性化の,異なる成分により支配されると推論された。HXIの軌道内バックグラウンドのモンテカルロシミュレーションは,各層の観測されたバックグラウンドスペクトルを再現し,それによって上記の仮説を定量的に検証した。さらに,バックグラウンドを低減するために電子遮蔽の包含を示唆した。Copyright The Authors Translated from English into Japanese by JST.【JST・京大機械翻訳】
