论文摘要
中性物质(TAN)的靶吸收器代表了大型强子对撞机(LHC)中最放射性区域之一。由Heraeus制造的七个40厘米长的二氧化硅杆,在Atlas实验周围的一个TAN中,由中性(BRAN)探测器组辐射。这项活动发生在2个P+P数据获取期间,该数据发生在2016年至2018年之间。本文报告说,辐射的融合二氧化硅材料的单位长度的光学传输是波长(240 nm -1500 nm)的函数(240 nm -1500 nm)的函数,剂量(最多18 mgy),以及在制造过程中引入的oh和h $ _2 $ _2 $ dopant的水平。使用CERN Fluka团队进行的蒙特卡洛模拟估算了输送给杆的剂量。
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.
