论文摘要
HADRONIC FORFESS（HF）检测器是CMS的子检测器之一。它在测量正向喷气机和缺失能量中起着重要作用。 HF位于CMS相互作用点的两侧，约为$ \ pm $ 11 m，覆盖CMS的非常前角，在伪范围内（3.0 <| $η$ | <5.0），仅留出光束管道的许可。该量热计由嵌入铁吸收器中的石英纤维组成。由带电颗粒产生的Cherenkov光通过纤维传输到PMT。由于质子 - 蛋白质碰撞而引起的纤维暴露于高辐射。这种辐射会在整个时间内导致纤维恶化。特殊通道被放置在HF检测器中，以观察由于辐射引起的纤维变化。可以使用这些渠道的数据在线监视辐射损坏。在这项研究中，使用2010年运行期间采取的局部数据分析了HF的辐射损伤。为分析方法提出了许多创新和修改。
Hadronic Forward(HF) detector is one of the sub-detectors of the CMS. It plays an important role in the measurement of forward jets and missing energy. HF is situated on both sides of the CMS interaction point, at about $\pm$11 m, covers the very forward angles of CMS, in the pseudorapidity range (3.0 < | $η$ | < 5.0), leaving only clearance for the beam pipes. This calorimeter consists of quartz fibers embedded in the iron absorber. Cherenkov light created by the charged particles is transmitted to PMTs by the fibers. Fibers due to the proton-proton collisions are exposed to high radiation. This radiation causes deterioration of the fibers over the time. Special channels are placed in the HF detector to observe the changes in the fibers due to radiation. It is possible to monitor radiation damage online using the data taken for these channels. In this study, radiation damage of HF is analyzed using the local data which was taken during 2010 run period. A number of innovations and modifications have been proposed for the analysis method.
