| 摘 要： | 本文报道了我们采用改进的Bridgman法为欧洲核子研究中心(CERN)大型强子对撞机(LHC)上的紧凑型μ子螺线管(CMS)实验生长的大尺寸掺Y3+钨酸铅闪烁晶体,给出了晶体的光学和闪烁性能,如光致发光谱、X射线致发光光谱、纵/横向的透射光谱、光产额以及辐照硬度.测试结果表明,掺Y2O3的钨酸铅晶体光产额很高(>13pe/MeV),且全为100ns以内的快发光,其辐照硬度已接近CMS电磁量能器(ECAL)端帽晶体的要求,同一批晶体彼此间的性能一致性好.

| Abstract: | In this paper, we presented the study of large-size Y~(3+)-doped PbWO_4 crystal grown using a modified Bridgman method for the CMS experiment at the Large Hadron Collider at CERN. The optical and scintillation properties of the crystal were given, including photo-luminescence and X-ray stimulated luminescence spectra, longitudinal and transverse transmittance spectra, light yield, and radiation hardness. The measurement results indicate that the crystal has very highlight yield values (>13 pe/MeV), fast scintillation within 100ns, and the radiation hardness close to the need for CMS-ECAL End Cap crystals. A good consistency is shown among the same batch of crystals. |
