论文摘要
已经进行了一项研究，以了解辐射损伤对考虑升级CMS检测器的强子量热仪的各种塑料闪烁瓷砖的影响。用未辐照的瓷砖和在CMS碰撞大厅被辐照的瓷砖进行测量，达到44 kgy的剂量。根据能量谱，效率，效率与击中每个瓷砖的位置以及光产率的位置有关，对不同形状的瓷砖提出了结果。所有瓷砖的光降低量高达约50％。当前在CMS检测器中使用的形状的瓷砖没有看到光收集的不均匀性增加，而被视为替代方案的瓷砖观察到了显着的不均匀性。
A study has been performed to understand the effects of radiation damage on various plastic scintillator tiles considered for a possible upgrade of the hadron calorimeter of the CMS detector. Measurements were made with unirradiated tiles and with tiles that had been irradiated in the CMS collision hall to a dose of 44 kGy. Results are presented for the tiles of different shapes in terms of the energy spectrum, efficiency as a function of the position at which each tile was hit, as well as light yield. All the tiles showed a light reduction of up to about 50%. The tiles with the shape currently used in the CMS detector did not see increased non-uniformity of light collection, while a significant disuniformity was observed for the tiles considered as alternatives.
