抄録/ポイント： LUX ZEPLIN(LZ)実験は式そう器クライオスタット内の10トン液体キセノンの全検出器を用いた暗黒物質粒子相互作用を探索している。活性検出器体積にクライオスタットの大きな質量と近接は極端に低い固有放射能材料の使用を必要とする。適切な金属,radiopure生産を制限する因子の決定,LZクライオスタットと他の検出器成分の構築のためのチタンの選択を同定し放射能測定キャンペーンを報告した。チタンは~238U_<1.6mBq/kg,~238U_<0.09mBq/kg,~232Th=0.28±0.03mBq/kg,~232日L=0.25±0.02mBq/kg,~40K<0.54mBq/kg,~60Co<0.02mBq/kg(68% CL)の活性で測定した。チタンのこれまで報告された最低のいくつかは,このような低い固有活性は将来の暗黒物質と他の珍しいイベント検索のためのその使用を可能にする。モンテカルロシミュレーションは,この放射能とのLZクライオスタットから期待されるバックグランドの寄与を評価するために実施した。5.6トン基準質量のWIMP探索曝露の1,000日では,クライオスタットは0.160±0.001(stat)±0.030(sys)数の平均バックグラウンドに貢献すると思われる。Copyright 2018 Elsevier B.V., Amsterdam.
