论文摘要
作为未来的希格斯或Z工厂，已经提出了圆形电子正电子对撞机（CEPC）的构建，以精确测量希格斯玻色子。面向粒子流动的电磁热量表（ECAL）和辐射热量表包括针对CEPC量热法系统的基线设计。 CEPC量热法工作组正在开发闪烁剂 - 刺激性ECAL（SC-ECAL）原型。 SC-ECAL是一个采样量热仪，由交替的吸收层和高粒度活性层组成。从各个方面研究并优化了活动层的每个组件，以满足设计要求。完整的技术SC-ECAL原型将包含30层基于ECAL的单元（EBU）板，并与30层吸收剂交替。原型的前两层已经开发出来，并且已经进行了主要调试以验证其性能。
As a future Higgs or Z factory, construction of the circular electron positron collider(CEPC) has been proposed to precisely measure Higgs bosons. A particle flow-oriented electromagnetic calorimeter (ECAL) and a hadronic calorimeter comprise a baseline design for the CEPC calorimetry system. The scintillator-tungsten ECAL (Sc-ECAL) prototype is being developed within the CEPC calorimetry working group. The Sc-ECAL is a sampling calorimeter consisting of alternating absorber layers and high granularity active layers. Each component of the active layer has been studied and optimized from a variety of aspects to meet the design requirements. The complete technological Sc-ECAL prototype will contain 30 layers of ECAL-based unit (EBU) boards alternating with 30 layers of the absorber. The first two layers of the prototype have been developed, and primary commissioning has been performed to validate their performance.
