在欧洲核子研究中心大型强子对撞机上辐照的熔融石英材料的光学透射特性
Optical Transmission Characterization of Fused Silica Materials Irradiated at the CERN Large Hadron Collider
AI总结：
本文系统表征了在LHC高辐射区辐照后、具有不同OH和H₂掺杂规格的熔融石英棒在240–1500 nm波长及最高18 MGy剂量下的光学透射特性，为高辐射环境光学材料选型提供关键数据。
摘要：
中性粒子靶吸收器（TANs）是大型强子对撞机（LHC）中放射性最强的区域之一。由贺利氏公司制造的七根40厘米长、具有不同掺杂规格的熔融石英棒，被中性粒子束流率（BRAN）探测器组安装在ATLAS实验周围的一个TAN中进行了辐照。该辐照活动发生在2016年至2018年之间的Run 2质子-质子数据采集期间。本文报告了对辐照后熔融石英材料单位长度光学透射率的完整表征，该表征作为波长（240 nm - 1500 nm）、剂量（最高达18 MGy）以及制造过程中引入的OH和H$_2$掺杂水平的函数。传递到这些石英棒上的剂量是利用CERN FLUKA团队执行的蒙特卡罗模拟估算的。
英文摘要：
The Target Absorbers for Neutrals (TANs) represent one of the most radioactive regions in the Large Hadron Collider (LHC). Seven 40 cm long fused silica rods with different dopant specifications, manufactured by Heraeus, were irradiated in one of the TANs located around the ATLAS experiment by the Beam RAte of Neutrals (BRAN) detector group. This campaign took place during the Run 2 p+p data taking, which occurred between 2016 and 2018. This paper reports a complete characterization of optical transmission per unit length of irradiated fused silica materials as a function of wavelength (240 nm - 1500 nm), dose (up to 18 MGy), and level of OH and H$_2$ dopants introduced in the manufacturing process. The dose delivered to the rods was estimated using Monte Carlo simulations performed by the CERN FLUKA team.
