论文摘要
多用途检测器(MPD)旨在研究在NICA加速器复合物(俄罗斯Dubna)的SQRT(SNN)= 4-11 GEV的重离子碰撞中形成的热和密集的重物。 MPD光谱仪的大型电磁热量表(ECAL)将为| ETA | <1.2的中央伪率区域中的光子和电子提供精确的空间和能量测量。 ECAL的Shashlyk型采样结构已针对光子能量范围从约40 MeV到2-3 GEV进行了优化。量热计的细分分割和投射几何形状可以从Au-au反应中处理高度的二级颗粒。在本次演讲中,我们报告了ECAL的设计,施工状态和预期参数。
The Multi-Purpose Detector (MPD) is designed to study a hot and dense baryonic matter formed in heavy-ion collisions at SQRT(sNN)=4-11 GeV at the NICA accelerator complex (Dubna, Russia). Large-sized electromagnetic calorimeter (ECal) of the MPD spectrometer will provide precise spatial and energy measurements for photons and electrons in the central pseudorapidity region of |eta|<1.2. The Shashlyk-type sampling structure of the ECal is optimized for the photons energy range from about 40 MeV to 2-3 GeV. Fine segmentation and projective geometry of the calorimeter allow to deal with high multiplicity of secondary particles from Au-Au reactions. In this talk, we report on a design, a construction status and expected parameters of the ECal.
