背景圆形正负电子对撞机（CEPC）被认为是未来的Higgs/Z工厂。在电磁量能器（ECAL）的选择中，选择了一种钨芯夹层结构（ScW）的取样量能器。其有源层由厚度为2 mm、尺寸为5 × 45 mm 2的闪烁体塑料条组成，由硅光电倍增管（SiPM）读出。为了提高光输出的均匀性，我们对闪烁体单元进行了优化，包括不同SiPM耦合结构的闪烁体条的光输出分布，研究了耦合槽形状和尺寸对光输出均匀性的影响。在带的底部中心处具有跑道形耦合槽的闪烁器单元的均匀性可以达到4%而不降低光输出。与优化前的非均匀性情况相比，基于Higgs → γγ重构的均匀性优化后的玻色子质量分辨率提高了约23%，与完全均匀情况相当。
BackgroundThe circular electron positron collider (CEPC) was proposed as a future Higgs/Z factory. A sampling calorimeter with scintillator-tungsten sandwich structure (ScW) is selected as one of the electromagnetic calorimeter (ECAL) options. Its active layers consist of plastic scintillator strip units with a thickness of 2 mm and a size of 5 × 45 mm2, read out by silicon photomultipliers (SiPM).PurposeThe light output has non-uniformity along the length direction of the scintillator strip, which affects the resolution of the ScW ECAL. It is necessary to control the non-uniformity to a low level.MethodsWe present the optimization of the scintillator units to improve the uniformity of the light output, including the light output distribution of the scintillator strips with different SiPM coupling configurations, and the impact of the coupling groove shape and dimension on the light output uniformity.Results and conclusionThe results show that the non-uniformity of the scintillator unit with a runway-shaped coupling groove at the bottom-center of the strip can achieve 4% without reduction in the light output. Compared to the case of non-uniformity before optimization, the optimized uniformity improves the boson mass resolution about 23% based on the reconstruction of Higgs → γγ, which is comparable to the perfect homogeneous case.
